I'm planing to build a battery pack this summer and i was wondering if this setup could work. The tp4056 boards are really cheap and I've got a few lipos around I want to make a use of it. My goal is 3s2p or 4s2p with one board per lipo cell (even 7p is of interest, but that is another build). Now I was thinking wiring from Vout on the board to a motherboard connector (something with a lot of connectors) so that I can disconnect the entire bank for charging. Take a look at the picture, it is supposed to be a 3s pack, but I'm not sure if it will work. When charging =NO load and when load = no charging. Tp4056 have a built in protection circuit why I would like to use those. I would appreciate your help on this. What I know about the board is that Batt+ and Vout+ are same, but Batt- and Vout- are separated by a mossfet that protects the battery. And of course 3s lipos batteries do not sum up to 12V exactly, that is not the issue here. Question is if this setup would work, i.e. When charged, I can connect them in series and the output is ~12V or I fry the circuit/batteries/both!?
