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

BMS HCX-3999 for 7.4V 2S Li-ion/Li-Polymer Battery Packs (4A Charge, 4A Discharge)

1. Battery management circuit board for 7.4V 2S Li-ion and Li-polymer battery pack.
2. BMS/PCB/PCM applies for 2 cells Li-ion/Li-polymer battery pack.
3. To prevent the battery packs from overcharge,overdischarge,over current, over temperature ,short circuit.
4. The Maximal working current: 4A.
5. Compatible with both Li-ion and Li-Polymer cells.

We keep materials in stock only, we need around 3-7 days for samples productions.
