Appreciate your comments, however I don't understand what you mean by
"1S,2S,3S and 4S....in serie" If you mean in series,such batteries in series will not work in this circuit, I connected two 3.7V batteries in series to this circuit and it got damaged. 7.4V was in excess for this type of power bank circuit.

Great fix there, dear Imoudu! That was a professional job, which also involved its own intricacies. But you managed it very well! Thanks for sharing. The article also contained very valuable info!

Indeed the 1S, 2S, 3S and 4S charger (BMS) boards are only for 1,2,3 or 4 cells in serie. And all boards also have a maximum current they are able to deliver. Glad you were able to make good use of your 1S Li-ion charger board.
