Features:

1. With a communication port for SMBus interface via USB tool bridge to PC to gather battery information, helpful for engineering or R&M services.
2. Monitoring battery SoC and SoH, such as amperes, volts, capacity; temperature, protection status and cell balance, cycle life times, event records etc. 
3. With circuitry of blocking back electromotive forces(BEMF), and filter circuitry against noises or interference.
4. Smart two-way cell balance design for both in charging and in quiescence.
5. LED display to show battery capacity, based on Coulomb Counter and, to show protection occurrences.
