100% brand new 16 cell Lithium iron phosphate LiFePO4 batteries (48V) 40A (60A Peak) protection PCB w/Balancing





Description:

This Lithium iron phosphate battery protection PCB protect 16 cells Lithium iron phosphate (48V). 40A 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.
This New version of PCB has LED to indicate which cell has been fully charged and balancing is in action

Lithium iron phosphate LiPO4 protection is necessary, as the battery will be damaged when they are over discharged or overcharged


After 
Lithium iron phosphate 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


Connection:

Please see above connection diagram
Method 1: Both Charge and Discharge using same wire: Connect to C-
Method 2: Seperate Discharge and Charge: C- for charge, D- for discharge

Procedure:
1. Connect your 16 cells in series (cells should be identical) (or for 32 cells: 2cells parallel, 16 cells in series) etc.
2. Then connect the batteries to the PCB according to the picture above.
3. Activate the circuit by charging using Constant current/Constant voltage charger.


Protection MOSFET:  7x100N03


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