Upower Lithium Battery 12.8V/300Ah - UE-12LI300

Upower Lithium Battery 12.8V/300Ah - UE-12LI300

The Upower 12.8V/200Ah lithium battery is a powerful battery designed for those who need a lot of energy, great autonomy and maximum reliability for many years and without complications, because you don't want to have to worry about it. Just install it, connect it and forget about it.

It is a very efficient battery, offering more useful capacity, better performance and a much longer life than conventional batteries.
Unlike AGM or GEL batteries, with this battery you have no sudden voltage drops or loss of performance as it discharges.

Thanks to its lithium iron phosphate technology (LiFePO₄), this battery is particularly safe, stable and long-lasting.
It is maintenance-free, requires no ventilation, generates no fumes and maintains constant performance throughout its lifetime, making it a modern and efficient option for both fixed and mobile installations.

The Upower battery has an integrated battery management system (BMS), which means that it is protected against situations such as overcharging, over-discharging, current peaks, short circuits or extreme temperatures.
This means that it will look after both its own health and that of the connected equipment, providing stable and safe operation even under demanding use.

It is commonly used in solar installations, caravans, campers, boats, tour buses, power backup systems, electric vehicles, telecommunications and applications where power cannot fail.

Upower 12,8V/300Ah battery features

Performance

The Upower battery has a capacity of 300 Ah and a nominal voltage of 12.8 V, providing 3,840 Wh of usable energy.
In short: it gives you energy for longer and you use almost all of it, without having to recharge it as often and without worrying about voltage drops.

It can supply high currents in a stable manner, even when you connect power-hungry equipment, without sudden voltage drops.
Its cycle life is over 2,500 cycles at 100 % depth of discharge (DoD), which means it can last up to 10 times longer than many conventional batteries, so it has a very long life and no loss of performance.

In addition, its high discharge capacity allows it to withstand consumption peaks when connecting power-hungry equipment all at once, and the battery maintains a very stable voltage during discharge so that devices operate without sudden drops.
Therefore, your equipment works just as well, is protected and does not shut down prematurely, even if the battery is already quite discharged.
This is especially valuable in systems where a stable 12 V source is needed for electric motors, lighting, pumps, electronics or solar inverters.

Design

The Upower 12.8V/200Ah comes in a robust monoblock format, meaning that all cells are integrated into a single compact unit, using lithium iron phosphate (LiFePO₄) cells.
This type of lithium is much safer than other technologies because it does not heat up easily or have risks (fire or premature failure) like other types of batteries, making it a very safe option.

Although it has a high capacity, it weighs considerably less than a similar AGM or GEL battery, which makes it easy to install in caravans, campers or boats.

In addition, its internal design consists of 4 cells connected in series and 4 in parallel, ensuring balanced power distribution and reliable operation for years to come.
The Upower battery can work in parallel configurations (up to 4 units), allowing to expand both the voltage and the total capacity of the battery bank according to the needs of the system.

Intelligent Battery Management System (BMS)

The Upower battery has an internal intelligent battery management system (BMS) that takes care of the battery at all times by acting as a protection system.

The BMS continuously monitors how each battery cell is charged and discharged and prevents problems such as overcharging, deep discharge, short circuits or extreme temperatures, keeping the battery within safe parameters at all times.

Thanks to this system, the battery protects itself, extending the life of the battery, preventing damage to both the battery and connected equipment and giving you peace of mind.

Temperature

The Upower 12.8V/200Ah battery can operate without problems in quite demanding temperature conditions, both charging and discharging:

• Temperature of cargo: between 0ºC and 45ºC
• Temperature of download: between -20ºC and 60ºC

It can therefore be used both indoors and outdoors.
However, it is recommended that if you are not going to use it for a long time, it should be stored between -10ºC and 35ºC.

Protections

The Upower battery, in addition to the BMS, has many safety features that increase its reliability, so it comes very well protected.

It has systems that defend against overloads, deep discharges, power surges, short circuits and extreme temperatures.

It also has additional safety components such as high temperature thermal fuses, flame retardant additives and pressure relief valves.

In addition, its housing is IP65 protected, so it is resistant to dust and splash water, which is very useful in boats, campers or outdoor installations.

Installation and maintenance

Thanks to its single-block format, this battery is very easy and quick to install. No complex configuration or advanced technical knowledge is required.

It can be easily integrated into 12V systems and also allows series and parallel connections to create larger battery banks if more voltage or capacity is required.

It is also a maintenance-free battery, as it does not require ventilation, does not generate gases, does not need to be topped up and does not need to be checked periodically, making it a very convenient and safe option in the long term, especially in closed or poorly ventilated environments. It is installed and it works, so you can forget about it.
