Home->PCM for LiFePO4 Battery Packs ->For 11S~13S Packs (35.2-41.6V)-> For 12S Packs (38.4V)

12S LiFePO4 BMS with CANBUS communication,programmable bms for LiFePO4 battery packs

Part number: HCX-D328

Features and Benefits

Programmable BMS With RS485, RS232, CANBUS, SMBUS, I2C Communication protocol (6S~16S)
 
1.Protection Circuit Board for 12S 38.4V LiFePO4 battery pack;
2.PCB applies for 12 configuration 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.
