BMS ( Battery Management System ) BMS is higher level BMS, which is safety control and management
system to monitor battery status in order to make battery better
working and lengthen battery life time objectively. 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.
