1.Protection Circuit Board for 88.8V 24S 55A Li-ion and li-polymer battery pack;
2.PCM/BMS applies for 24S Li-ion and Li-Polymer battery pack;
3.With overcharge/overdischarge protection;
4.With cell balance function;
5.Compatible with Lithum ion and Li-Pomyer cells.

6.How balancing function works? after 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 cells have longer service life.
