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

BMS D276 for 77.7V 21S Li-ion/Li-Polymer Battery Packs (55A Charge, 55A Discharge)

1. Battery management circuit board for 77.7V 21S Li-ion and Li-polymer battery pack.
2. BMS/PCB/PCM applies for 21 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: 55A.
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.
