Okay, so my battery pack is originally composed of 100 cells in a 20s 5p configuration. Well, I had a group of 5 cells in P go bad alone with the bms frying, so I need to replace them. I have 4 leftover cells from when I originally built the battery so I need one more. My original cells I bought from Aliexpress and the specification of the cells is as follows.
Cell Specification
3.7V 3.4AH
Maximum Continuous Discharge Current (A)
30A
It being from Aliexpress, I would take the listed specifications very loosely.
Anyway, I bought a used HP 24 cell battery pack for cheap to replace the cell and add another group in P. The HP cells are 1500mah rated. https://batteryhookup.com/products/hp-43-2v-module-with-24x-30a-lg-18650-cells
Anyway, I know mixing 1500mah and "3400mah" cells in P isn't ideal if the groups aren't even but I don't think it will matter much if it's just one cell since it will be slightly less mah than the other groups. Thoughts? I've heard that it will just pull current from the cells with the highest voltage.
Also, please remind me, do I need to worry when connecting fully charged cells to other cells that are less charged?
