I have four 25,6 V 200 Ah LiFePO Smart batteries with EasySolar 48/5000 in a solar power system on a boat. Because we normally have no electric network available equalization of the batteries is not possible. However they have kept well balanced until now when one of the batteries is showing imbalance in VictronConnect app.
Now I have brought the boat to electric network and charged the batteries through the EasySolar. After reaching 100% SOC the imbalanced battery still shows imbalance because two center cells have 3,36 V and 3,29 V. I kept charging over night but the EasySolar gives only 30 – 40 W even if it shows bulk mode charging. Perhaps BMS has something to do with this although it's not giving any alarm.
CCGX has a equalization option in settings but every time I try to start it I get ”Charger not ready, equalization cannot be started.” Funny thing is that after over night charging all batteries are now showing imbalance even if their cell voltages are within 0,01 volts except the one that is really imbalanced.
Should I now take the imbalanced battery out and cahrge it separately?
