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

BMS D704 for 37V 10S Li-ion/Li-Polymer Battery Packs (20A Charge, 40A Discharge)

1. Protection Circuit Board for 37V 10S Li-ion and Li-Polymer battery pack;
2. PCM applies for 10 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.
