Part Number:

Protection Circuit Board with 65°C thermostat and Fuel Gauge Socket For 36V NiMH/NiCd Battery Packs 


  • This protection circuit is specially designed for 36V NiMH/NiCd Battery pack with upto a max of 7A discharging rate.
  • Keep 36V NiMH/NiCd Battery pack from over-discharge (30V)
  • Max discharging /charge current <7A
  • Over discharge protection: 30±1V
  • Power consumption: 1.5mA (no fuel gauge installed)
  • No over-charge protection
    • Must use the correct voltage charger to properly charge the battery pack!
  • Has short circuit protection during discharge
  • With 65ºC thermostat and Fuel Gauge Socket
  • To reset the PCB:
    • Connect a 36V charger to "Reset" the pcb once the pcb is open when battery pack voltage drop below 29.1V
    • If you have a multi-voltage charger, it might not "reset" the pcb, you can "reset" the pcb by:
      • Connect the charger directly to the Batt+ and Batt- of the pcb
    • If you cannot remove the load, then you can add an on/off switch like this to "reset" pcb and start charging:
      • battery-------->pcb------> switch --------->load
    • Dimension (LxWxH): 60mm(2.4") x 30mm(1.2") x  6.10mm(0.25")
    • Weight: 11 grams (0.4Oz) 
    • Working Temperature: 60±5°C

    How to connect PCB on battery packs

    • Bat+ = 36V Positive = Input Positive
    • Bat-  = 36V Negative= Input Negative
    • OUT+ = Vout+ = Charge + / Discharge + = Output Positive
    • OUT-  = Vout-  = Charge - / Discharge - = Output Negative


    • Misusing PCB may cause battery damage or explode.  We are not responsible for any damage caused by user.
    • Don't use this PCB with Li-Ion / LiFePo4 battery pack
    • Must charge battery up to 36VDC minimum
    • Must disconnect load from PCB to "Reset" PCB before charging
    • Since this PCB does not have over-charge protection function, must use our 36V NiMH/NiCd smart charger to recharge 36V battery pack.
