  • This battery management system is designed to support from a 4 cells (12.8V) LFP Prismatic module of 20Ah, 40Ah , 60Ah,  100Ah or 200Ah upto a maximum of 80 cells, 500Ah capacity and max of 500A discharge with visual display function.
  • A distributed system measuring voltage and temperature of each cell
  • Daisy chain connection supporting up to 80 cells
  • Cell balancing
  • Integrated Ground Fault Detection and alarm output
  • Pack voltage measurement
  • Pack SOC calculation
  • Low voltage and high voltage alarm cutoff outputs
  • Optional CANBUS or MODBUS communication output
  • Composite video output
  • Perfect for Electric Car, Electric Golf Cart or other application where you are looking to replace the original lead acid battery with LiFePO4 cell to reduce the weight, improve cycle life and newer technology.

Package Content

  • 1 x Master Controller Module (Size 146 x 68 X 50 mm)
    • The Master Module functions are:
      • Communicate with each Slave Module on monitoring the max/min voltage, max/min current and temperature & perform balance function on each cell.
      • Provide all necessary Data to Display on the LCD Display
      • Provide connection to the Shunt to measure the current
      • Provide connection to the momentary switch to change the information being display on the LCD Display
      • Provide signal to open the Discharge Relay, Charge Relay (if not use with a CANbus charger) to protect the battery pack from over charge, over discharge or high temperature
      • Provide connection to a CANbus charger ( no charge relay will be need!)
  • 1 x 7" LCD Display:
