Building a battery pack with 18650 (tesla) cells is a complex and tricky job due to the large amount of cells and connections. Without specific equipment, the essential fusing per cell to build a safe battery system is virtually impossible.

For this reason we offer a nice and easy solution for building blocks that consist of loose battery cells that are all individually fused and placed in a safe module. The Power Battery modules also have the unique and “patent pending” ability to cool the battery modules with liquid. This improves efficiency and life span and many higher (continuous) currents may be compared in the battery modules compared to uncooled or air cooled battery modules.

These “Extreme 12P” Power Battery modules are produced with the latest Samsung 25R 18650 cells with extremely high discharge specifications. Great for applications with very high specifications such as electric racers. Other type of cells (Samsung, Panasonic, Sony, LG) on request
