Home->PCM for Li-ion/Li-Polymer Battery Packs -> For 5S Packs (18.5V)

Protection Circuit Board(PCB) for 5S 18.5V Li-ion/Li-Polymer battery pack

Part number: HCX-D211

Features and Benefits

 1.Battery management circuit board for 18.5V 5S Li-ion and Li-polymer battery pack;

2.BMS/PCB/PCM applies for 5cells 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.
