For the Netherlands, shipping costs are €6,75.
From €150,= we deliver free of charge in the Netherlands except on the Wadden Islands.

All products are packed in sturdy boxes. We use packing material to ensure your products don't move or get damaged too much inside the boxes. The packing material we use is biodegradable.

We also try to reuse the filling material that we receive from our suppliers as much as possible.

To protect the environment as much as possible, we try to reuse boxes. Therefore, you may receive a product from us in a box from one of our suppliers. We only reuse boxes that still meet our strength standards.

We ship battery packs with GLS. To keep total costs as low as possible, the batteries are shipped in their original packaging. This also minimizes the risk of slipping and tearing.
It's possible that GLS will deliver your order's boxes on two different days during sorting at the shipping hub, meaning your order will be completed the next day. If your order isn't complete on the second day, please call us immediately, and we'll resolve the issue: 085-401 92 30

For shipping to Belgium we charge €10 per shipment.
From €150,= we deliver free of charge in the Netherlands, Belgium and Germany, except for the Wadden Islands.

It's very good that you're asking yourself (and our FAQ) this question; there are plenty of online shops that cannot be trusted.
That's why we've partnered with Kiyoh, a highly reputable review platform. Here, you can read more than 400 reviews about our online store and the service we provide.
It is not without reason that we score an 8,8 at Kiyoh.

We have been around for 10 years and supply to several very large companies in the Netherlands.
Our details can be checked with the Chamber of Commerce -> 63967588.

Shop4power/Shop4networks ships with GLS, DHL, and sometimes PostNL. This guarantees reliable delivery within 1 to 2 business days. To ensure same-day shipping, place your order before 15.00:1 PM and avoid bank transfer as the payment method, as this will result in a 2-XNUMX day delay. Track & Trace information will be provided as soon as possible, so you'll always be updated on your order's status.

For heavier battery packs, we use a regular carrier. In these cases, standard parcel delivery services are unable to deliver the order undamaged. Unfortunately, this regular carrier does not have track & trace information. You pay a €6,75 contribution to the shipping costs per shipment; for shipments to Belgium, this contribution is €10. Orders over €150 are shipped free of charge in the Netherlands and Belgium.

All battery pack orders are shipped with extra strapping and tear-resistant tape. This prevents the boxes from tearing during shipping. Because we ship these batteries with UPS or our own carrier, we can be sure the boxes will be handled properly. Should a box accidentally fall during transport, this extra tape will ensure you receive your product. Scooter batteries and heavy UPS battery packs are shipped with a regular carrier, so we don't have track & trace information for you. The carrier will leave a note in your mailbox if you are unexpectedly not home.

Your products are packed in sturdy boxes with environmentally friendly padding so that even if they experience heavy handling during shipping, you'll still receive an undamaged and fully functional product. You may also encounter packaging sent to us by our suppliers. We strive to reuse all shipping materials as much as possible to be as environmentally friendly as possible. If your delivery arrives in a (severely) damaged box, please take a photo of the box immediately and make a note for the driver. This way, we can file a damage claim with the carrier on your behalf later. If you accept your package without any comment, it will be virtually impossible for us to subsequently file a damage claim with the carrier and/or reimburse you for any damage.

If you would like to know what we do to minimize our impact on the environment, you can always call us or send an email to info@shop4power.nlWe'd be happy to tell you more about this. If your delivery unexpectedly doesn't arrive within two business days, please contact us so we can take action! Paying by credit card can result in a delay of up to one day. The credit card company must release the invoice before we can process the payment.

To replace the batteries, you will find some helpful tips below!

We assume that replacing the battery of your eScooter is necessary. If you are not sure, you will find a few tips to find out in the FAQ "Do I need new batteries for my eScooter?"

We assume you've purchased the correct battery. If you're unsure, or haven't purchased the battery yet, you can find some tips on purchasing the right battery under the FAQ "How do I determine the right battery for my eScooter?"

You've now purchased the correct battery. There are two options:
1. The complete battery set is in a cassette
2. The batteries are built into your scooter without a cassette.

1. The complete battery set is in a cassette.
If possible, take precautions: Wear work gloves and safety glasses.
Disconnect the cassette from the scooter.
Carefully unscrew the cassette, normally the cassette consists of two parts, the part where the screw heads are located is usually a “lid”.
If you've exposed the batteries, I recommend taking photos of the wiring with your smartphone or digital camera. This way, you can easily trace the wiring. If you see a fuse, check it. If you don't have a multimeter, you can use a simple battery (AA or AAA) and a bicycle light. (Of course, make sure it's disconnected from the four blocks!)
Remove the wiring from the terminals. While doing so, check that all connections are still clean.
Remove the old batteries and install the new ones in exactly the same manner as the old batteries.
Reattach the cassette and connect the charger, or place the cassette in the scooter and connect the charger. The batteries will be approximately 70% charged upon receipt. Let them charge thoroughly overnight, and they'll be ready to use.

2. The batteries are built into your scooter without a cassette.
If possible, take precautions: Wear work gloves and safety glasses.
An eScooter with batteries installed without a cassette always has a DC switch to disconnect the batteries from the motor. Open this switch. If you can't find the switch, make sure you don't turn on the ignition!
Before removing the batteries from the scooter, I recommend taking photos of the wiring with your smartphone or digital camera. This way, you can easily trace the wiring. If you see a fuse, check it. If you don't have a multimeter, you can do this with a simple battery (AA or AAA) and a bicycle light. (Of course, make sure it's disconnected from the blocks!)
Remove the wiring from the terminals. While doing so, check that all connections are still clean.
Remove the old batteries and install the new ones in exactly the same manner as the old batteries.
Make sure all cables are routed exactly the same way and don't get pinched or damaged by chafing. Secure them in the same way and connect the charger. The batteries are approximately 70% charged when you receive them. Let them charge thoroughly overnight, and they'll be ready to use.

Why am I not allowed to put old and new batteries together in a remote control? The explanation is below.
In the case below, it concerns a customer with a scooter with 5 12Volt batteries, so a 60V scooter.

To give a short example: The charging voltage of a 60Volt lead-acid charger is: 73,5 Volt.
So if there are 5 identical batteries in series, each battery will be charged with: 73,5 / 5 = 14,7 Volts.
The recommended charging voltage for cyclic batteries is 14,5 – 14,9 Volts, so that's fine.
Because the batteries are connected in series, the same current will flow through all of them.

Ohm’s law is U = I x R – voltage = current x resistance.
Because the resistance is fixed and the current is the same everywhere (series connection), the voltage across the different blocks will vary.

The internal resistance of a CPC33-12 is approximately 12 mΩ, of a CPC38-12S it is approximately 8 mΩ
The voltage distribution over the batteries is then: 12+12+12+8+8 = 52
The CPC33-12 battery – 73,5 / 52 * 12 = 16,96 V
The CPC38-12S battery – 73,5 / 52 * 8 = 11,31 V

So one battery breaks down because it gets a WAY too high charging voltage and the other one goes
broken because it never gets fully charged.

Unfortunately we don't have any manuals for the eScooters.

The main reason for this is that eScooters often entered the Netherlands in different ways. Normally, they didn't come with batteries, which were installed in the Netherlands.
Each dealer had their own preference for batteries and installation methods, making it impossible for us to say with certainty what the battery configuration of your eScooter is.

We can assist you with installation. If you send us photos, we can show you how the batteries should be installed. We can also replace the scooter batteries for you. We can provide a cost estimate based on photos showing how the batteries are installed.
We can also replace batteries in a battery cassette for you if desired.

In principle you can replace the batteries yourself, if you are careful this is really not a problem.

Determining the right battery pack for your eScooter or other electric device isn't that difficult. Here are a few tips:

1. Determine the number of batteries. It's crucial to know how many batteries your device has. Sometimes this is difficult to tell, so you can measure them. If you measure around 48 volts, there will be 4 batteries, and if it's closer to 60 volts, there will be 5. If you can't measure, you can check whether the DC/DC regulator (usually a metal box measuring 15 x 6 x 4 cm or something similar) has a voltage reading on it. Ultimately, your batteries will have to be removed from the scooter for replacement!

2. Determine the battery capacity. The capacity is usually indicated on the blocks. If the capacity isn't indicated on the blocks, you can measure the blocks and send this measurement to us at info@shop4power.nl. We can then tell you the battery capacity.

3. Check the size of your battery. While it's good to use a battery of approximately the same capacity, the size is more important. Check that the dimensions of your current blocks match the dimensions of the new set on our website. This information can be found under the "Technical Information" tab for the products.

The data, especially the capacity, doesn't always match. While we're talking about a 33 Ah block, your current one might actually have 35 Ah. Such differences aren't a big deal. It mainly has to do with the measuring method and the data you're using.
The most important thing is that the dimensions and quantity are correct.

To ensure that you can enjoy your batteries for as long as possible, we have put together a number of tips for you.
To make it a bit clearer, we have divided the tips into two types of rider.

– Intensive user (long distances, daily use)
Charge immediately after a long drive

– Regular rider (short distances, daily use)
Do not charge daily, at least once a week

For short distances, only charge the batteries when the battery indicator shows 50% or at least once a week!
DO NOT interrupt charging and do not disconnect the charger until the green LED lights up.

When should you replace the batteries in your eScooter, Golf Trolley or other electrical device?

You'll often notice your eScooter's range decreasing. This is the best indicator of a battery pack that's aging. As long as the decrease is acceptable, it's fine. If the decrease is no longer acceptable, you'll need to replace the pack.

If you still have a dead battery after charging overnight when you want to drive away, do the following:
– Take a DC voltmeter/multimeter. Measure the voltage across the battery terminals on the charger connection. The voltage will be around 12-13 volts; if you don't measure anything at all, a fuse might be blown. Note this measured voltage and connect the charger to your battery. Let the charger charge for a minute and measure the voltage across the terminals again. If the voltage increases slightly, your charger is still working. In that case, you'll need to replace the charger.

If the voltage at the connections is 0 volts, you'll need to locate the fuse and test it. If it's defective, replace it, charge it, and test again. If the problem is solved, enjoy! If the voltage is still 0 volts, a fuse block is defective, and you'll need to replace the set.

If your current scooter batteries are GEL batteries, then your current charger is also a GEL battery charger. It's best to buy a GEL battery charger as well.

A GEL battery has a lower maximum charge voltage than regular lead-acid batteries. If you replace the GEL batteries with regular cyclic lead-acid batteries and charge them with a GEL battery charger, the blocks will never be fully charged. This means the range is lower and the batteries will fail more quickly.

So there are two options:
1. Buy GEL batteries again (available in the webshop
2. Purchase regular cyclic lead-acid batteries in combination with a regular cyclic lead-acid battery charger, available in the webshop

Batteries cannot be returned as we cannot verify whether they have been used or not.

A gel battery is a more robust version of a lead-acid battery because the acid in the battery is more viscous. This makes the gel battery more resistant to deep discharge. A scooter has a controller that prevents the battery from being discharged too deeply. Therefore, using a gel battery is actually unnecessary. Our importer recommends using "regular" lead-acid batteries. PLEASE NOTE! If you are replacing gel batteries, then you have a gel charger; in that case, you must purchase gel batteries.

The difference between the two Li-Ion versions, T1 and T2, is only in size. At the same Ah, of course.

A set of batteries, purchased immediately, also ages immediately. As batteries age, their internal resistance changes and increases.

In an aging set the following things can happen:

– The capacity decreases. Often, the voltage across the blocks is still the same when measured, and the decision is made to replace the entire set.

– Blocks are getting thick – A 12-volt lead block consists of six cells, so 6 x 6 volts = 2 volts. At some point, lead plates in a block can make contact. This causes a cell to fail.
This reduces the voltage across this block, as there are now 23 cells instead of 24. This means that the 6-cell blocks receive 12,5 volts instead of 12 volts.
(values are different for charging voltages, this is easy for the calculation example).
So if you measure the blocks, you will measure 3 blocks that have actually recently received TOO high a voltage, those blocks therefore appear to function perfectly.

The choice is clear! Add one new block and go!

So now we have 3 “old” blocks and 1 new block with a lower resistance.
The same current flows through all 4 blocks (series chain), Ohm's law U = I x R means that the voltage across the old blocks is higher than across the new block.
The old blocks are now really having problems because they are constantly overloaded and therefore break down. Often, plates then collide, causing one block to lose voltage and the rest of the
Blocks will become even more tense. They often become bulging and actually break.
Then you still have to replace 3 old blocks.

If you're lucky, the "new" block hasn't sustained any damage from the events. Then you can connect the three new blocks in series with the relatively new block.

If you are unlucky, this new block will have suffered a blow and you will need four new blocks.
If you are very unlucky, you think you are done with three new blocks, but then the worse new block still destroys the other three.

Is that number with the S after it important or not? Yes, it is very important. The charger and battery must have the same S number to function properly. A lithium battery is actually made up of many small cells connected together to achieve the required capacity and voltage. The cells can be connected from + to -, in series, and a row of serial cells can then be connected from + to + and from - to -. Serial connection increases the voltage, and once you have the correct voltage, you can connect several cells in parallel to achieve sufficient capacity. The 13S and 14S models are for 48-volt scooters, and the 16S and 17S are for 60-volt applications. It is therefore important to choose the correct charger for the number of cells in series, otherwise the battery will overcharge or not fully charge. The technical specifications of each charger state how many cells are connected in series.

Almost all electric scooters are equipped with 4 or 5 batteries. Many customers are misled because they only see 3 batteries when they open the scooter. However, there's usually another battery hidden underneath the others. To check how many batteries you have without opening the entire scooter, you can check the charger. If the charger says 48V, 48VDC, or 48Volt, then there are 4 batteries in the scooter. If it says 36V, then there are 3 batteries. The metal box, which you can often see when you remove the seat, often also shows the motor voltage. If you're still unsure or haven't been able to find it, please feel free to contact us: 085-4019230 or info@shop4power.nl

Driving distance depends on the number of Ah (ampere-hours). This is the capacity of the battery pack. If you have lead-acid batteries, you can choose batteries with a larger capacity, but you must carefully consider the size, as a higher capacity also means a larger battery. If the larger battery doesn't fit, you have another option: switch to lithium. Lithium has a much higher energy density, so you can store many more Ah lithium batteries in the same space than with lead-acid batteries. Keep in mind that switching to lithium also requires a different charger. In fact, a 30Ah lithium battery can travel much further than a 30Ah lead-acid battery. An electric scooter can operate without problems with either lead-acid or lithium batteries.

Shop4power supplies batteries from various manufacturers. For cyclic batteries, we often supply batteries from the same supplier. Below, we've compiled a table with the dimensions of each battery type in mm for this supplier, Intercel.

The difference between the Normal Cyclic battery and the Extreme version is the number of discharge cycles. The Extreme is capable of delivering even more discharge cycles than the Normal Cyclic battery, which was specifically designed for these applications.

The 38Ah S* has a capacity of 38Ah with a 20-hour discharge! The capacity of the other blocks is based on a 10-hour discharge.

The network cable may be a maximum of 100 meters long after a PoE injector. After that, the voltage drop across the cable is so high that proper operation of the connected PoE equipment can no longer be guaranteed.

WHY?
A copper cable (or other material) always has a resistance of Ω (ohm). When current flows through a cable I, some of the total voltage Ut across the cable, Uv, will be lost due to the cable resistance R.
This is because the voltage Uv is created by I x R.
The longer the cable, the greater the resistance.

In order to have an acceptable voltage at the end of the cable, it should not be longer than 100 meters.

If you need a cable longer than 100 meters, you'll need a PoE extender, such as the PoE-E101 or the PoE-E201. Using a PoE extender, you can increase the maximum distance several times. These PoE extenders can be ordered from our webshop.

Your PoE device must comply with an IEEE802.3a standard, such as the IEEE802.3af or at standard. You can find this information in your device's specifications. Sometimes a brand uses its own PoE standard, and in that case, it's not entirely certain we can supply it. Our Planet products comply with internationally established standards.

There are a few things you need to pay attention to:
– The network speed
– The required power
– Injector, splitter or extender
– Normal use or industrial application

The Network Speed:
We have 10/100Mbps but also 10/100/1000Mbps injectors and splitters in the package.

The required power:
We offer standard PoE systems, as well as High Power PoE and Ultra Power PoE. These can be used, for example, for dome cameras with pan, zoom, and tilt functions.

Injector, splitter, or extender:
This is often a mistake because a splitter is cheaper than an injector. An injector is placed at the beginning of the network cable, after which the network cable is extended to the user. If the user uses PoE, the cable can be connected directly. If not, the splitter can be used to split the Data-PoE signal into a data and a power connection. If you want to use a Data-PoE signal for distances exceeding 100 meters, you'll need an extender after 100 meters, either the PoE-E101 or PoE-E201.

Normal use or industrial use:
At home or in the office, you can simply use standard Planet solutions, but if you want to install equipment outside or in factories or other damp, cold, or warm locations, you're better off choosing an industrial Planet POE solution.

If you want to use Power over Ethernet, there are a number of things you need to pay attention to:

First, you'll need to check whether the equipment you're connecting is PoE-compatible. Next, it's important to check whether the PoE device complies with the IEEE 802.3af/at standard.

If the equipment is suitable, you've completed the output side. Then you need to add PoE to the network cable on the power side. This can be done using a PoE switch (802.3af or at, depending on the standard the user complies with) or an injector. If you already have a switch or modem/router that doesn't inject PoE, it's useful to use an injector (single-port or perhaps multiple-port). Note that if you have 802.3at users, the injector/switch must also be 802.3af. If you only have 802.3af users, an 802.3af switch/injector is sufficient, but you can also use an XNUMXat switch/injector, perhaps with future consideration.

The length of the cable is also important. A standard network cable should not exceed 100 meters. If the cable is longer, you can use a PoE extender. Again, make sure you're using 802.3af or at.

The Hikvision or any other camera can normally be powered in two ways:

– 12V 1A or
– PoE (IEEE802.3af)

The IEEE802.3af standard indicates that you can use a fast ethernet solution.
It does not necessarily have to be a gigabit POE solution.

The misconception is that PoE power is 12 volts. That's not true. PoE voltage is much higher, around 48 volts.

For your application, that doesn't matter. There are roughly three ways to do this:

– Do the data cables come from one central point and do we still have to switch?
– use a POE Switch
– Do the data cables come from one central point and no switching is required? – use a PoE injector hub.
– Do the data cables come from different starting points:
– use PoE injectors.

You already indicated that a Switch was not necessary.

If you're connecting multiple cameras from a single point and you already have a switch, you can use a PoE injector hub. With such a hub, you first connect each cable that would normally go to the camera to the hub, and from there, you continue to the camera, but now with PoE injected into the cable. Depending on the number of cables, you can choose a 4-, 12-, or 24-port solution. If each cable runs from a different location to different cameras, it's best to choose injectors. In your case, it might be the PoE-151.

If you think you have chosen a complete standard with the IEE802.3af standard, you are almost right.

The standard works fine; the only thing you need to pay attention to is the pin assignment. Within the 3af standard, there are two ways to use the conductors: MODE A (Endspan) and MODE B (Midspan).

In Mode A (Endspan), both data and power are transmitted over wires 1, 2, 3, and 6. The other two wire pairs are not used in 10/100TX.

In Mode B (Midspan), data is still sent over addresses 1, 2, 3 and 6, but now power is sent over the two unused wire pairs 4, 5, 7 and 8.

At shop4power, the "Technical Information" tab always clearly indicates whether a product is a Midspan or an Endspan, and it also clearly indicates which pins are used for PoE power. If you then compare this information with the product you're powering, you should be fine.

We use sturdy boxes for shipping, and we always ensure that the batteries are separated by cardboard to prevent damage and to prevent the contacts from connecting.

To prevent the batteries from damaging the box due to their heavy weight, we use special lengthwise reinforced PP tape with fiberglass threads. This tape is virtually impossible to tear.

There are a huge variety of UPS systems on the market, and some even come with different battery packs. The manual usually specifies which battery replacement you need.

If this is not the case, you can find the correct blocks through the supplier.

APC UPS systems always have a model number that helps you find the right battery. The image below shows an example of an APC model number (SMT1500MI1U).

The only solution that always works is to open your UPS and take a picture of the batteries inside. Email them to us with their dimensions: info@shop4power.nl. We will let you know within 4 hours which battery is right for you.
You can also email us the brand and model of the UPS you are replacing the battery for, and we will tell you which battery you need.

We continuously try to adapt our sets to all UPS systems available on the market. However, it's possible that your UPS isn't on this list, and you still think this is the right battery set for you. The best option at that point is to contact us by email at info@shop4power.nl or by phone at 087- 87 594 87.

We supply solution kits. The various kits are delivered complete, but without cables and fuses.

In the text of the batteries we indicate how many blocks there are in the battery set.
This quantity is also the number of blocks we supply for the listed price. These are NEW batteries, specifically designed for use in UPS systems from brands such as APC, MGE, BELKIN, CHLORIDE, etc.

Shop4power is part of Maas Energy Systems BV (MES).

MES always keeps batteries in stock for service purposes. We need a ready-made supply for our customers. It's difficult to always have "fresh" batteries because we don't need them constantly. By also selling these batteries as RBC sets through shop4power, we can always have "fresh" batteries available for both the webshop and MES customers.

Because of this structure, we're less interested in high margins and more interested in high throughput. The easiest way to achieve this high throughput is by offering very competitive prices in our webshop.

How do I find the right battery replacement for my UPS?
It is almost impossible for us to include all descriptions with the sets.

APC often uses abbreviations, for example, the Smart UPS is called SU. If you have an APC SmartUPS 750, you can search for it using su750.

Of course, the RBC number is also often found on the back of the UPS or in the manual.
Many sets are the same so that sometimes makes it confusing for you.

You can also email us the dimensions of your current batteries, so we know exactly which set you need.

If you're really stuck, you can send us an email at info@shop4power.nl, and we'll always respond within an hour (7 days a week, 08:00 AM - 22:00 PM). You can also call us at 087-87 594 87.

WE HAVE ALL SETS IN STOCK!!!!

We supply the battery packs without mounting hardware. Many suppliers charge exorbitant prices for these sets. This isn't necessary. With our blocks, you can simply reuse the materials and save considerably.

We supply the same quality batteries as those already in your system as standard. All single-phase (230V) UPS systems are supplied with commercial-rated batteries. This means the batteries typically last 3-5 years. If you think your batteries have been in service much longer, there's a good chance they've been defective for a while but haven't been used. A standard UPS only detects a defective battery when it's under load, for example, during a power outage.

For this reason, it's also wise to have your UPS battery checked every three months. Some UPS systems allow for this to be configured through software, while others can be tested from the front of the unit.

We can supply you with the right batteries for all UPS systems, and we can even supply all single-phase (230V) UPS systems from stock. Our standard inventory allows us to supply approximately 100 UPS systems with batteries per day.

If you prefer batteries with a longer lifespan, this is also possible, just send us an email: info@shop4power.nl

Most alarm systems use a single 12-volt, 7-Ah power strip. This strip is identical to the ones used in a UPS. For this application, you can use the S4P-RBC2.

The Fiber ports of the Scodeno switches communicate with other Scodeno switches, but not with switches from other brands.

• Use the switch's management tool to open the "optical port self-negotiation mode." This should resolve the issue.

It is always difficult to determine the total power of equipment.

Ultimately, measuring is still the best method. Maas Energy Systems can perform an on-site power measurement for you. If you prefer not to have a measurement, you can also check the equipment's nameplates for the power consumption per device and add these values together. However, please keep in mind that the power ratings listed on computers and similar devices are usually in watts, not kVA. The easiest way is to write everything down and contact us. We can give you an approximate estimate of your power consumption.

The tricky part about working with the power and/or current ratings listed on equipment nameplates is that these data are usually based on the power supply installed in the system. For example, the fact that a power supply can deliver 450 watts of power doesn't mean the computer it's built into actually consumes this amount of power. The actual power consumption when reading the nameplates is often much lower than when measuring the power consumption. You can always send us a list of equipment to be protected, and we can use this list to determine the total power consumption. When selecting a UPS system, also consider growth and reserve capacity due to, for example, switch-on phenomena (a device that normally draws 500 watts, for example, might draw four times that amount when switched on).

The term UPS stands for “Uinterruptable Power S"Upply" means an uninterrupted power supply. This term is very broad and encompasses all available UPS models.

Other terms for UPS include:
– No Break
– Emergency power unit
– Power supply
- Etc.

There are different UPS systems:
– On Line – Double Conversion – True online – VFI UPS
– Line Interactive
– Digital On-Line
– Offline
– Static UPS
– Rotary UPS
- Etc.

The autonomy of a UPS, also called hold time, runtime, or backup time, is the time the UPS is able to power the load "autonomously," meaning without mains power. Essentially, we're talking about the size/capacity of the battery. The choice of autonomy depends on several factors.

First, you need to decide what you expect from the UPS.

– Is the UPS used to bridge the time until the NSA (emergency power generator) has started up?
Then the UPS only needs to have a few minutes of autonomy.

– Should the UPS immediately bring down the IT systems in the event of a power failure?
Then the autonomy must be at least as great as the time required for the shutdown.

In the event of a power failure, would you like to have time to investigate the cause? For example, tripping a circuit breaker or something similar?
In this case, you should consider for yourself how much time such an investigation would take, and you should also add the time the IT systems need to implement the shutdown.

– Do you simply want to stay on the air as long as possible? This is often the case, for example, when powering telephone exchanges; we have to be available to our customers until the very last moment!

This last option presents the biggest challenges. With a large battery, you need to consider several things:
– How big and ESPECIALLY heavy is this battery set going to be?
– Isn't it financially more interesting to buy an NSA in combination with a UPS and a small battery?
A battery can be too big for a UPS, or rather, the UPS charger. What does this mean for the recharge time?

Many of Shop4power's UPS systems offer the option of expanding their autonomy with additional battery cabinets. These are then connected to the UPS unit. For UPS systems where this isn't possible, you can increase autonomy by choosing a slightly larger UPS. This can sometimes be financially advantageous.

An On-line UPS, also called a double-conversion UPS, is the only “real” No Break system.

With an online UPS, the rectifier converts the total power consumption of the UPS into a DC voltage. Both the battery and the inverter are connected to this DC voltage at the output. In this configuration, the inverter at the output doesn't know whether it's being powered by the rectifier or the battery.

In "Mains-powered" operation, the rectifier powers the inverter and also maintains a "trickle charge" on the battery. If the mains power fails, the inverter's power is taken over by the battery without interruption, so the load will not notice any difference between mains and battery power. Because the term "On-line" is not protected and can therefore be used for other types of UPS, it is also sometimes referred to as a "True On-Line UPS."

What is protected is the term VFI. This term is an abbreviation for Voltage, Frequency Independent. This means that the UPS is independent of voltage and frequency. The UPS does not need to run on battery power when there is a variation in voltage or frequency.

A Line-Interactive UPS can handle voltage fluctuations without battery operation, but not frequency fluctuations. This UPS is then called a VI-UPS. Voltage independent
An offline UPS cannot handle voltage and frequency variations without battery operation. This UPS is then called a VFD-UPS. Voltage and frequency dependant.

There are several UPS systems.
The three most famous are:

Offline.
Line-interactive.
On-line (double conversion)

A line-interactive UPS is largely similar to an off-line UPS. The main differences are that a line-interactive UPS has a better filter. Furthermore, a line-interactive UPS is equipped with a "fader," meaning that when the mains voltage becomes too high, such a UPS can "fade" it to an acceptable level without switching to battery power. Some line-interactive UPSs are also equipped with a "booster," which can increase a low voltage without battery operation. Typically, a line-interactive UPS has a sinusoidal output voltage when operating on battery power.

A line-interactive UPS can be used for LAN environments such as CAD workstations and less critical servers.

Unfortunately, the UPS names are not protected, and they are therefore frequently misused.

Off-line
An offline UPS is also called a standby UPS. This type of UPS system is often used for loads that are not sensitive to very short interruptions. When mains power is available, the UPS simply maintains a (internal) battery charge and transmits the input power to the load. In the event of a power outage, an offline UPS switches from normal power to battery power. The UPS contains an inverter that converts the DC voltage from the battery(ies) to AC voltage, usually a single-phase AC voltage.

An offline UPS is also called a standby UPS. This type of UPS system is often used for loads that are not sensitive to very short interruptions. When mains power is available, the UPS simply maintains a (internal) battery charge and transmits the input power to the load. In the event of a power failure, an offline UPS switches from normal power to battery power. The UPS contains an inverter that converts the DC voltage from the battery(ies) to AC voltage, usually a single-phase AC voltage. Because the inverter is only "on" during normal operation, it will have to switch during a failure, resulting in an interruption of 5 to 10 ms. This type of UPS has a small rectifier at the input that only maintains the battery charge.

Because an offline UPS only switches between mains and battery power, such a system is set to a certain permitted variation (bandwidth) in voltage and frequency. The system operates within this bandwidth; outside of it, it powers the load from its battery. More advanced computer systems, in particular, are sensitive to very small variations in voltage and frequency. An offline UPS is not suitable for these computer systems and other sensitive/expensive systems. Furthermore, an offline UPS is usually equipped with a simple inverter that cannot produce a sinusoidal AC voltage. Often, this UPS produces a square wave or trapezoidal wave. Many devices cannot operate with this. Therefore, it is important to check whether your equipment functions with a trapezoidal or square wave.

An offline UPS is usually equipped with a very simple filter or even no filter at all. A filter protects your equipment from mains pollution. This protection is minimal, if any, with an offline UPS.

Because an offline UPS uses its rectifier only to charge the battery, it is relatively compact. This allows for significant cost and size savings. The same applies to the inverter, which only operates during a power outage or when the voltage or frequency fluctuates outside its bandwidth. This allows for the use of a lighter/smaller inverter. These cost and size savings make offline UPSs smaller and less expensive than line-interactive and online UPSs.

It can be argued that an off-line UPS is suitable for less critical workstations, for example, and to give a home computer the opportunity to safely "save" data in the event of a power failure before shutting down.

Unfortunately, the UPS names are not protected, and they are therefore frequently misused.

Both the battery and the inverter are connected to this DC voltage. In this configuration, the inverter is unaware whether it is being powered by the rectifier or the battery. In "mains operation," the rectifier powers the inverter, and the battery is also maintained on a "trickle charge." If the mains power fails, this power from the inverter is taken over by the battery WITHOUT INTERRUPTION, so the load knows NO difference between mains and battery power. Because the term "online" is not protected and can therefore be used for other types of UPS, it is also sometimes referred to as a "True Online UPS." Because a True On-Line UPS uses a rectifier and an inverter to continuously supply the load with full power, these components are much heavier than those in an off-line UPS and a line-interactive UPS, making a true on-line No Break system relatively expensive.

A True On-Line system can be used anywhere where reliability and power quality are important. A True On-Line UPS provides the best protection for critical equipment!

It remains difficult to explain why different voltage values are used. The most commonly used value for a battery is the Nominal Voltage, which is the average voltage of a battery. In addition, batteries have a maximum charging voltage and a minimum voltage. Generally, the nominal voltage is the most commonly used, but chargers often also list the maximum charging voltage. This is because lithium batteries use different numbers of cells for the same nominal voltage (just to make things easier :-)).

For example, a 48-volt lithium battery can be 13S or 14S. For an explanation, see the scooter batteries section above. A 13S battery has a nominal voltage of approximately 46,8 volts, which is 13 x 3,6 volts. A 14S battery has a nominal voltage of approximately 50,4 volts. 
The 14S battery has a maximum charging voltage of 58,8 volts – 14 x 4,2 volts. The maximum charging voltage per cell for lithium-ion batteries is 4,2 volts.
The 13S charger/battery also has a lower maximum charging voltage: 54,6V

Why do we keep calling all these chargers and batteries 48 volts? That probably stems from lead-acid batteries, where a battery is always 12 volts. And everything here is a multiple of that. So, 12, 24, 36, 48, 60, 72

For lead-acid batteries, it's all very simple: you just need to know whether you have a GEL or an Acid battery, nothing more.
In addition to lead-acid batteries, we supply two other types of chargers: LiFePo4 and Lipo/Lion chargers.

Below is a list of different maximum charging voltages. 
LiPo/ion
– 12Volt 4S – 16,8Volt
– 24Volt 7S – 29,4Volt
– 30Volt 8S – 33,6Volt
– 33Volt 9S – 37,8Volt
– 36Volt 10S – 42Volt
– 40Volt 11S – 46,2Volt
– 48Volt 13S – 54,6Volt
– 48Volt 14S – 58,8Volt
– 60Volt 16S – 67,2Volt
– 60Volt 17S – 71,4Volt
– 72Volt 20S – 84Volt

Lifepo4
– 12Volt 4S – 14,6Volt
– 24Volt 7S – 25,6Volt
– 24Volt 8S – 29,2Volt
– 36Volt 12S – 43,8Volt
– 48Volt 15S – 54,8Volt
– 48Volt 16S – 58,4Volt
– 60Volt 20S – 73Volt
– 72Volt 24S – 87,6Volt

So if you see a different voltage on the charger's nameplate than the usual 24 or 36 volts, the values above may provide some clarity.
