Lithium Ion battery 48V 25Ah – LiFePO4 – PowerBrick®

The Lithium 48V 25Ah battery was created thanks to the know-how of PowerTech Systems. Company specialized in the design of high performance lithium ion lithium batteries.


The PowerBrick® battery product line offers a high degree of safety through the use of cylindrical cells in Lithium Iron Phosphate LiFe (LiFePO4) technology. It incorporates an innovative control system (BMS, Battery Management System). It ensures a very high level of safety in use.
The BMS constantly monitors and balances the battery cells. This protects it and increases its lifespan.

The Lithium 48V 25Ah lithium battery is protected by a waterproof ABS case that resists splashing water and dust (IP55 protection for a PowerBrick® STANDARD battery or IP66 for a PowerBrick® PRO+ battery).

Replacement of lead batteries

The PowerBrick® product line has been designed to replace lead-acid batteries. It offers a quadrupled energy capacity for reduced weight and space requirements.

Simple installation

Each 48V 25Ah lithium battery has a nominal voltage of 51.2V. They can be connected in series (up to 2 batteries in series) and in parallel (up to 10 batteries). Thanks to its technology, the PowerBrick 48V 25Ah battery can be installed in all directions (vertically or horizontally, standing or lying down). The final assembly voltage can be 48V or 96V. This corresponds to almost all the different electrical applications (traction, solar storage, wind power).

The 48V 25Ah LFP battery pack is ideal for AGV (automated guided vehicle), marine, boats, forklifts, robots…

Batteries designed to have a better ecological footprint!

The 48V 25Ah PowerBrick® Lithium battery is twice as light and environmentally friendly for all types of use. These batteries can directly replace old generation batteries. The latter are poorly performing and very harmful to the environment through the use of heavy metals. But also, they are constrained by the difficulty of recycling them (batteries Lead VRLA, AGM or OPZ batteries).

The PowerBrick® range has a 2 or 5 year commercial warranty.

    Great product ! High power, long duration. I replaced my old fashion lead acid battery on my electric boat. I now have constant power and very long endurance up to the end of discharge. Really good product.
