BMS/PCM/PCB - Li-ion/Li-Polymer BMS PCM PCB

BMS D707 for 44.4V 12S Li-ion/Li-Polymer Battery Packs (30A Charge, 60A Discharge)

1. Protection Circuit Board for 44.4V 12S Li-ion and Li-Polymer battery pack;
2. PCM applies for 12 cells Li-ion/Li-Polymer battery pack;
3. To prevent the battery packs from over charge, over discharge, 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.
7. PCM comes with all the voltage detection wires and connectors.
We keep materials in stock only, we need around 3-7 days for samples productions.
