3-S Balance Charger for Li-ion and Li-po
This is a very simple Balance charging circuit based around TL431 current regulator/shunt I/C.this circuit consists of 3 units . each unit can charge a individual cell with CC and CV method.
The best part of the circuit is that you can modify it to charge 2,3,4,5,6,7,8....N series cell as this is very simple and not affected by the number of cells in series
All the componets used are easy to get and THT so that anyone can just solder and use the circuit.
i used the given circuit to charge my 3S Li-PO battery of Self made quad copter.
Thank you.
