1.Protection Circuit Board for 96.2V 26S Li-ion and Li-polymer battery pack; 
2.BMS applies for 26 cells Li-ion/Li-polymer battery pack; 
3.with overcharge/overdischarge 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.
