Remarks:
The PCM is specially designed for 6.4V Li-Ion Battery pack with 5A discharging rate. Different than normal PCB, it provides balance function after battery pack is fully charged. PCM detects each voltage and trim higher voltage down until other cells reach the same voltage level. Therefore, it helps Li-Ion cells have longer service life.
