BMS is mainly used in high capacity li-ion/li-polymer/lifepo4 battery packs. BMS is advanced integration of management, protection, communication and self-diagnose and cell balancing.
Major functions: 1. Overcharge protection 2. Overdischarge protection 3. Overcurrent protection 4. Overheat protection(NTC) 5. Short circuit protection 6. Temperature sensing 7. Cell monitoring & balancing 8. Communication interface 9. Self-diagnose 10. Power gauge Parts included: 1.60v 50ah Lithium Battery pack with high quality BMS board build in and free case. 2. 67.2V 5A Charger(With EU/US/UK/AU AC Charger plug you can choose ) Remark: We offer lithium, lifepo4 and ni-mh battery, accept customized battery pack, we can't update all items here. If any battery you want, please take it easy to contact with me tell me the capacity, voltage and size you want, thanks.
