Hey everyone, I'm looking for some advice!
I have a 12v 280ah DIY LifePo4 battery bank that I have top balanced a while ago. I have finally fitted it into my RV and attached some load. I have noticed that one of my cells drifts massively when load is applied to the battery, but when the load is reduced the cell comes back in line.
I wondered if there is anything I can do about this? They were top balanced to 3.6v before being put into 12v 4S. Then sat for around 4 week at around 70% capacity. I fitted the battery to my RV this morning and let the MPPT charge them to 14.2 Absorb and then I attached a 12v fridge which pulls are 3/4amps every now and again.
When the fridge is idle, all 4 cells are matched closely, however under load cell 1 drifts a huge amount which has got me worried.
