Home->PCM for LiFePO4 Battery Packs ->For 6S~10S Packs (19.2-32V)-> For 9S Packs (28.8V)

Protection Circuirt Module for 9S 28.8V LiFePO4 Battery Packs with 5V(isolated) output

Part number: HCX-D175

Features and Benefits

with 5V(isolated) output
1.Protection Circuit Board for 28.8V 9S LiFePO4 battery pack;
2.PCB applies for 9 cells LiFePO4 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 all the LiFePO4  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.
