12v Lithium-Ion battery pack – PowerBrick+

12V Lithium-Ion battery pack

PowerBrick+ 12V Lithium-Battery


PowerTech Systems offers a range of 12V Lithium-Ion battery pack to meet most of our customer needs (up to 48V). PowerBrick®+ battery offer a high level of safety through the use of cylindrical cells in Lithium Iron Phosphate (LiFePO4) technology.

Each PowerBrick®+ embeds a BMS (Battery Management System) inside its casing.

PowerBrick®+ solutions advantageously replace lead batteries, offering more than doubled capacity for half weight and footprint.

Each battery has a 12.8V nominal voltage and can be assembled in series (4S maximum) and parallel (10P maximum) to reach operating voltages from 12V, and up to 48V..

For applications requiring higher voltage or energy, see PowerModule advanced systems.

PowerBrick+ battery is enclosed in a sealed ABS case, resistant to moisture and dust (IP 55 or IP 66).

PowerBrick+ are lightweight, reliable and environmentally friendly solutions for multiple usages. These batteries can take place for direct Lead-Acid batteries replacement.

Even if battery charge can be performed by most Lead-acid chargers, we advise to use a dedicated Lithium-ion charger.
