1.Battery Management System for 51.8V 14S Li-ion and Li-polymer battery pack;
2.BMS applies for 14cells Li-ion/Li-polymer battery pack;
3.with short circuit/over current protection;
4.With cell balance 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.
