BMS Mini


EMUS BMS Mini is a standalone Lithium battery management system for batteries consisting of up to 16 Lithium cells. It has all key BMS functions integrated into one device:

  • Cell voltages and temperatures measurement
  • Battery current measurement
  • Balancing of the cells
  • Integrated contactor to protect the battery
  • Integrated pre-charge circuit to allow soft start of motor controllers
  • Connectivity to various types of chargers
  • Connectivity to inputs to control the BMS and the battery
  • Connectivity to outputs to indicate battery status and control
  • Connectivity to Android smartphones for control and configuration


  • Robots
  • Scooters
  • Bikes
  • Motorcycles
  • Lightweight vehicles
  • Mobile storages
  • Heavy RC models
