I have two EVE 280 Ah LFP batteries (12V each) connected in series (24V) each with its own BMS. The BMS settings are identical. They are charged through a Growatt 3000W inverter through either solar or line AC. Early on the individual cell and total battery voltages were very close, but lately their normal charged status are quite different, say 3.35 vs 3.45 (cell averages) and 13.4 vs 13.8 (battery average). I’ve set the Growatt to charge to 27.5V, but that doesn’t even out the V differences between the two batteries. Am I being too concerned about this difference? Is that difference normal?
