About a month ago I took delivery of 4 SOK 100AH batteries with the BT feature. 3 of them have been outstanding! The 4th has a BMS that acts sick. It is all over the place on SOC reading and it doesn't seem to charge like the others. My Magnum Energy Inverter works well with the good 3 but when I just connect the suspect one, it goes crazy with short charge cycles that also cause all the LED lights in the RV to flicker. The other 3 do not do this. The battery cell voltages all look similar to the good batteries, but for whatever reason the BMS on the bad one never gets to 100% and charges randomly. Any thoughts???
