I have a few hundred new, non branded cells with about 1.9ah capacity and checked them all for IR (and wrote on each cell) and they range from 18 to 30.
I wanted to know how should I spread them the right way since for example I have 10pcs IR 18, 20pcs IR 19, 40pcs IR 23 and so on.
I know that it wouldn't be smart making a one parallel group of IR 18, one parallel group of IR 25 because it will lose balance really fast.
So if I mix in each 10 parallel cell group IR 18-28, is there importance if the next group in series has the same added IR value in the same order?
Is it smart to calculate added IR of all the cells in the group?
