PCM-L04S60-546-34-LiFePO4
4S-60A-LiFePO4
For 4 cells in series. Nominal current for charge & discharge: 60A
10 Items
This protection circuit is specially designed for a LiFePO4 Battery pack with 60A discharging rate. It provides a cell balancing function after the 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.
