JK 100A - 300A Universal and Smart BMS with built-in Active Balancer

The intelligent protection board of lithium battery is a management system specially designed for large-capacity series lithium battery packs. which has the functions of charging, high current active balance, protections such as overcharge, over discharge, over current and over temperature protection, coulomb counter, Bluetooth communication, GPS remote, etc.

The protection board can also connected Android and IOS mobile apps via Bluetooth to monitor the battery health and working status. Also, you can modify charge/discharge/balance parameters of the protection board.

The protection panel is compact, easy to operate which can be widely used in EV, scooter, shared car, high-power energy storage, base station standby power supply, solar power, and other projects.

Features:

• Supported battery types:
  • Lithium Iron Phosphate (LiFePO4/ LFP)
