1.Protection Circuit  Board for 55.5V 15S Li-ion and Li-polymer battery pack;

2.PCB applies for 15 cells Li-ion/Li-polymer battery pack;

3.To prevent the battery packs from overcharge,overdischarge,over current, over temperature ,short circuit ;

4.With cell balance/equilibrium function;

5.Compatible with both Li-ion and Li-Polymer 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.
