Pat didn't mean to failed to answer. I'm using small gauge alligator clips on the posts. I think the total resistance from A to B was almost 100 ohms so I could see your point there. You suggest I top balance I was trying to solve for one sagging cell shutting me down while looking like my SOC was fine when stopped. It seems like you're not the only one suggesting that as well so maybe I just give up now put them back into series since they're all within 0.15 volts of each other and let the BMS top balance. You asked what BMS I had it's the Zeva which does have Dynamic cell balancing even if it's very slow.
