Lithium Ion battery 12V 40Ah – LiFePO4 – PowerBrick®

The Lithium 12V 40Ah battery was created thanks to the know-how of PowerTech Systems. Company specialized in the design of high performance lithium ion lithium batteries.

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.


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 (built-in 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 12V 40Ah 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).

Simple installation

Each 12V 40Ah lithium battery has a nominal voltage of 12.8V. They can be connected in series (up to 4 batteries in series) and in parallel (up to 10 batteries).
Thanks to its technology, the PowerBrick 12V 40Ah battery can be installed in all directions (vertically or horizontally, standing or lying down). The final assembly voltage can be 12V, 24V, 36 or 48V. This corresponds to almost all the different electrical applications (traction, solar storage, wind power).

The 12V 40Ah LFP 12V battery is ideal for camper vans, marine, boats, caravans, robots…

Batteries designed to have a better ecological footprint!

The 12V 40Ah 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 product line is covered by a 2 or 5 years commercial warranty
