Per Overkill BMS, they cannot account for a large difference in Internal Resistance when it comes to balancing.
Is there a general rule of thumb for accounting for differences in Internal Resistance? I have heard so little about this previously but in my first big foray into building a battery pack I am finding this to be more and more of a concern. Basically a good BMS will stop mismatched cells from over/under discharging at the cost of capacity.
If I have a mixture of higher IR and lower IR cells is it worth matching the higher IR cells into the same 16S packs so the BMS can manage them similarly?
Thanks!
