Not sure if this question has been asked before, currently having a bulk amount of cells and trying to figure out 2 things.
1. What is the acceptable IR and Capacity range for a single parallel group. Example building a pack and there are 4 cells in parallel, ranging from 2500mah to 2900mah, and IR testings ranging from 30moh to 100moh, what range is acceptable?
2. What is the acceptable IR and capacity range between series cells. Example Parallel pack 1 contains 4 cells in parallel at 2500mah each (10AH total) and IR is consistent between those 4 cells at 50moh. Can this be connected in series to another parallel group that has 2900mah cells and 80moh of IR?
This is for a high drain pack, im aware for a low drain pack like a power wall high IR is o.k.
