I am working on a Li-ion battery pack with used cells from an old laptop battery. I have a doubt on how to correctly group these used cells so that I can get maximum efficiency out of the pack.
I am making a 1s5p battery pack with the following capacity
Cell1- 1909mAh
Cell2- 1919mAh
Cell3- 1166mAh
Cell4- 1483mAh
Cell5- 2037mAh
So if I group these cells in parallel how does the discharge of these cells happen? I mean since cell3 has the lowest charge capacity with 1166mAh compared to other cells, will other cells also discharge only up to 1166mA instead of their full capacity. Like for example, while discharging the battery pack cell3 would discharge to its bottom faster than any other cell and reach its cut off voltage of 2.65V and the TP4056 module would disconnect the load from battery pack even though other cells in the pack have not fully discharged or reached their bottom?
I am using the TP4056 charging module to charge this pack which also has DW01A protection IC on it. Please see the attached image for my setup.
