SPF-F-12-25 BMS

Specification

<1>. Feature

  1. With a communication port for SMBus interface via USB tool kit to PC to gather battery information, helpful for engineering or R&M services.
  1. Monitoring battery SoC and SoH, such as amperes, cell volts, battery capacity; temperature, protection status and cell balance, cycle life times.  
  2. Smart balance design for both in charging and in quiescence.
  3. Remaining capacity, based on Coulomb Count.
