Hi, my battery system has 920ah. After discharging 20% (184ah) bmv shows 87% soc instead of 80%. What settings do I have to tweak in order to get close to the correct soc?
Before all batterys were full and I synced manually. Thanks

BMV 712 wrong soc
Hello. I have the same issue with mu bmv 700. I have read many posts and my conclusion is that the BMV does NOT simply count the percentage of tha Ah drown from the battery. And this has to do with the current you are discharging. For example if you discharge 184 Ah with 20Amps the discharge percentage is different from discharging 184 Ah with 100amps. So the bmv takes in consideration many other parameters (current, voltage, peukert) before giving you the SOC. Try to discharge the battery with a different current to see the diference.
Your settings look OK.
