In October I picked up 2 x EASTAR BTS 12V 100Ah LiFePO4 batteries to replace the 2 marine batteries on the camper I purchased. The camper can charge them to 12v roughly but it lacks the charge controller to get full potential so I picked up a ECO-WORTHY smart charger to keep them topped off.
I use the xiaoxiang app to monitor the batteries and after my last camping trip I noticed that the cell balance didn't seem right with cell 1 sitting at around 3.3 and cells 3-4 reporting 3.6. I read somewhere that if I make sure there is no load on the batteries they will automatically rebalance and sure enough after about 4 weeks all cells were reporting 3.33x.
So today I hooked up the charger again and now I'm back to cell 1 sitting at 3.3 and the other cells at 3.6 (see attached pic).
So now I'm stuck trying to figure out what's causing the imbalance and how to fix it. Any help is appreciated.
