  • Cells Count :  3S - 8S
  • Maximal Voltage on P+ and P-: 35V
  • Maximal Voltage on B+ and B-: max. 35V
  • Charge Current: up to 25A
  • Discharge current: 0~25A continue, 100A burst
  • Current drain for balancing: 300mA/cell.
  • Balance accuracy: <10mV
  • Over Charge Protection Voltage: 4.20V/cell (LiPo), 3.75V/cell(LiFe)

  • Voltage display resolution: 0.001V 
  • Voltage Detection precision: 0.005V
  • Compact size: 115 x 68 x 15mm, or 4.52” x 2.67” x 0.59”
  • Weight:150g
 

Features: 
  • Detect and display pack voltage, difference of cell voltage and temperature, each cell voltage by microprocessor, 100% calibration before delivery make sure the high accuracy.
  • Over Voltage protection during charge, EJBMS-A8 will cut off charge and sound warning by beeper.
  • Under Voltage protection during discharge, EJBMS-A8 will cut off discharge and sound warning by beeper.
  • Over temperature protection during charge or discharge, EJBMS-A8 will cut off charge or discharge and sound warning by beeper.
  • Over current and short circuit protection:
    • Cut off discharge when 25A to 100A discharge current for different continuous time. It means the e-scooter don’t lose power under 100A, such as the e-Scooter can be powered at 40A for 1 second at least, and cut off, then resume automatically.
    • 100A or more when short circuit, cut off discharge automatically and resume 10 seconds later.
    • Dual protection by program and hardware, more reliable.
  • Low Quiescent current design, EJBMS-A8 draw current from all cells to keep the cell voltage balanced and minimize the power consumption in stand-by.
  • Approved by CE and 12 months warranty.
