How to Make a 3S Li-Po Battery Charger Circuit

For making this circuit we need three 230v to 5v,1Amp DC converter circuits and three TP4056 modules. Its a low cost 3s battery charging module.
For connections and assembly we need a Glue gun and a soldering iron. Maintaining a similar ampere dc converter circuits will be preferable for better charging of three cells simultaneously. I used old charger circuits of output 5v 1A. for this circuit

1.) 3 × TP4056 boards from robu.in

2.) 3 × Ac to 5v DC converter Circuits from amazon. You can also use old charger circuits of similar ampere. This is 5v 2A circuit board.

3) connecting wires
4) battery charger clip to connect it to the battery

Make connections as per Circuit diagram, Its very simple. Then your 3S battery charger is ready to use.
While charging LED's in TP4056 module indicates red color. After full charge these LED's will turn into blue color.

1) Check the polarity of Battery to this charger circuit that are connected properly or not.
2. Use multimeter to check the voltage of the charger circuit before charging the battery
3. Make the connection of the circuit male
connecter based on the polarity of the 3s battery female connector.
