I have a large number of cells that are all the same model.
I am also keeping them in groups as they were extracted as I have the manufacture dates of the packs.
Apart from testing theTP4056modules I have, I was considering putting each of the cell groups in a holder all in parallel for a while after charging, so they are all exactly the same voltage before they are separated and put away for self discharge testing. This way I only need to do 1 initial voltage check for all the cells in a group and drops in voltage may be more easily apparent.
I think paralleling the cells should also mean that they are exactly the same state of charge before capacity testing and should make capacity testing slightly more accurate.
What do people think of this idea?
