The LiEV-AB is a compact and cost-effective Active Balancing Battery Management System for automotive and industrial application. LiEV-AB BMS has two PCB's i.e. ACB (Active control Board) & BPB Battery Power board combines as LiEV-AB BMS. It manages rechargeable lithium batteries of any chemistry and from any battery supplier allowing you maximum battery sourcing freedom.

  Each LiEV-PB manages 6–16 cells in series and 8 temperature sensors. The LiEV-PB handles pack level measurements, data logging, application and charger interfaces.
