Remarks:
The PCM is specially designed for 6.4V* Li-Ion Battery pack with 7A discharging rate. It’s different from other PCB, whose balance function is built-in after battery pack fully be 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 and stable performance.
