Early on with LFP4 I was told (along w/other chemistries) that you wanted to use the same Generation for parallel or series configuration. I had a vague idea, but not really “why”. Buying my latest battery, cell matching was discussed, internal resistance (IR) seemed to be the compatibility issue. All my batteries are prismatic cells, even my first one. (Apologies to Rando for suggesting cylindrical superiority a while back)
The latest battery dealer thought with BMS (unless IR was notably different), doing its duty, you would stand to lose only 5% battery life over 10 years, (w/diff Gen) matching up in parallel. He thought, ballpark, 6 months. It was a quick calculation by him. I do not intend using a parallel setup more than a day(s) at a time.
I could really use some opinions from knowledgeable WTW electrical guys. I have recipe knowledge & a bit more, but lack the understanding of many contributors on this Forum. I’d like to understand the ramifications with running 2 different Gen, & different company’s, prismatic cell batteries, in parallel. He recommended using same Ah to same Ah only. Help?
