Item specifics

New: A brand-new, unused, unopened, undamaged item in its original packaging (where packaging is ... Read moreabout the condition

100% brand new Four cell Lithium iron phosphate LiFePO4 batteries 40A (60A peak) protection PCB w/Balancing


This Lithium ion phosphate LiFePO4 battery protection PCB protect Lithium ion phosphate LiPo4 batteries. 20A continous current. Suitable for electric drills, motors, or aircraft models which require heavy current load.

The PCB support Cell balancing features to prevent cell to cell variation. Balancing current is 80mA at 3.7V

Lithium ion phosphate LiFePO4 protection is necessary, as the battery will be damaged when they are over discharged or overcharged

After Lithium ion is connected to the PCB, the board protect individual batteries from:

1. Over charging - Disconnect circuit when either battery is over 3.75V
2. Over discharging - Disconnect circuit when either battery is lower than 2.0V
3. Short curcuit protection - Disconnect when short circuit is detected


Please see above connection diagram

1. Connect your 4 cells in series (cells should be identical) (or for 8 cells: 2cells parallel, 4 cells in series)
2. Then connect -ve of the cells to B-, then to B4, B3, B2, then B1
3. Activate the circuit by charging to P+ and P- using Constant current/Constant voltage charger.

Protection MOSFET:  8x100N03

1. Please use identical lithium LiFePO4 batteries when using this protection PCB
2. The usage of this PCB requires knowledge on lithium batteries, Please DO NOT buy if you do not know what you are buying or do not know how to connect.
