Protection Circuit Module with LED Fuel Gauge For 12V NiMH/NiCd Battery Packs
This protection circuit is specially designed for 12V NiMH/NiCd Battery pack with upto a max of 5.0A discharging rate.
- Keep 12V NiMH/NiCd Battery pack from over-discharge (10V)
- No over-charge protection
- Must use the correct voltage charger to properly charge the battery pack!
- Max discharging /charge current <5.0A.
- PCB will cutoff at 9.7V to protect battery pack from over discharge
- 5 LEDs display battery pack's voltage (press button to turn on LEDs indicators, it will turn off when you let go)
- LED1 (Red) = pack voltage: 10.8-11.5V (must recharge battery ASAP)
- LED2 (Yellow) = pack voltage: 12.5-12.9V (battery need recharging soon)
- LED3 (Green) = pack voltage: 13-13.4V
- LED4 (Green) = pack voltage: 13.5-13.9V
- LED5 (Green) = pack voltage: > 14V ( battery is fully charge)
- NO LED - disconnect the load (device) and recharge the pack ASAP!!
- To Reset the pcb:
- Connect a 12V charger to "Reset" the pcb once the pcb is open when battery pack voltage drop below 9.7V
- 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:
Features:
- Apply for 10 Cells NiMH/NiCd Battery pack with discharging current <5.0A
- Dimension (LxWxH): 50mm(2.0") x 30mm(1.2") x 10mm(0.4")
- Weight: 5.6 grams (0.2Oz)

Warning:
- 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 12VDC minimum
- Must disconnect load from PCB to "Reset" PCB before charging
- Since this PCB does not have over-charge protection function, must use our 12.0V NiMH/NiCd smart charger to recharge 12V battery pack.
