Remarks:
The PCM is specially designed for 9.6V LiFePO4 Battery pack with 4A discharging rate. Different than normal PCB, it provides balance function to ensure battery pack is fully charged. PCM will detect each cell’s voltage and trim higher voltage down until other cells reach the same voltage level. Therefore, it helps LiFePO4 cells have longer service life.
