Hello, I have a 1.2k off grid system I use for back up. I have 16 280ah lifepo4 batts. I charge them with a Victron 150/35 smart charger. I use a Daly 200 amp smart bms. Here’s the question, as soon as my charger goes into absorbing, one cell tends to run away. The 15 average is 3.4 (I run 90%) but the 16 hits 3.5. when the charger drops into bulk they level out quickly. So tips , tricks, or am I fine? Thanks all
