      • CC/CV, CC = 3.0A, CV = 4.20V Max per cell
    • Max charging current is 3.0A
    • Recommend charging temperature: 15'C (59F)~ 35'C (95F)
  • Discharging protection
    • Over-charge protection voltage for single cell: 4.25V/cell
    • Over-discharge protection voltage for single cell: 2.30V/cell
    • Over-current detection protection:12.0A
    • Short circuit protection
    • "O Voltage" output if any fault condition occurs
    • All fault are reset with charger input
Input power DC 16.0V - 18.0V ( > 60W) from charging terminal (Input Terminal)
Output
  • DC 12V - 16.8V from discharging terminal (Output Terminal)
  • Average idle power consumption is approx 325uA
Input/Output terminal 5.5mm x 2.5mm female barrel socket
Max. Charging rate 3.0A
Max. Discharging rate 12.0A (10A Continuous)
Fuel gauge
  • 4 LED built in the board to show battery charging/discharging status
  • Type: Voltage based
    • LED 1 for indicate battery charging status
      • LED 1status
        • Red LED 1= Charging
        • Green LED 1= Charging completed
          • Note:LED 1will remaingreen until unplugged from power supply
    • LED 2 - LED 4 indicate battery discharging status
      • LED 2- LED 4 status
        • LED 2 = Green = 30%
        • LED 2 & LED 3 = Green = 60%
        • LED 2  & LED 3 & LED 4 = Green = 100%
    • Included Press Fuel gauge switch to check the status of charge/discharge
    • In order to save battery power, LED will remain "Off" except when activated by press switch with auto 2 second time out

Warnings

  • Batteryspace is not responsible forany damage caused by misunderstanding and misuse!
  • Please read the instructioncarefully before assembling to battery pack.
  • Must connect withcorrect AWG wire based on American Wire Gauge table ) (Please clickhere to view)
  • Do NOT mount this CMB on a metal plate as that will cause a short and damage the CMB. The charging circuit and the discharge circuit are two separate circuits that must be "Isolated"
