Protection modules

Safety and cellbalancing boards for LiFePO4

Protection module for 4 cells LiFePO4 with current, overvoltage, and undervoltage protection

Protection module

The pcb will take care of safety on all cells with LiFePO4 technology in order to have a transportation approval. The leads is to connect the balancing function between the cells to obtain maximum lifetime. The battery management systems is designed to work with A123 Lithium nanophosphate but works also perfect with other Lithium iron phosphate technologies
