EG4 Battery charging issue using coms

Batteries on Bms test say 100% and inverters say 85%. WTH
To fix the inverter reporting incorrect SOC... Flip your battery breakers off and on one at a time starting with the primary battery and working your way down the list.

Edit: assuming you are use EG4 Type.

Is this normal behavior or is their a problem will battery or BMS
Typical behavior for my EG4 LP4 batteries. It took weeks to top balance. Last time I checked, I still have one cell in one battery that runs away 0.13v over while the other cells are all within 0.02v

When Using EG4 type I have 4 batteries that hit 58v no problem 1 that hits 58v occasionally and the 6th battery with the runaway cell that runs high never hits 58v without a OCV warning.
