12V Lithium-Ion battery pack – PowerBrick+

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.

PowerBrick battery 12V has a 12.8V nominal voltage and can be assembled in series (4S maximum with PowerBrick 12V, 2S maximum with PowerBrick 24V) and parallel (up to 16P) to reach operating voltages up to 51.2V.

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.
