Victron SmartBMV battery monitor keeps resetting to 100%!

I have read other responses to the problem of the Victron SmartBMV 712 battery monitor resetting to 100% SOC, even when the battery is almost discharged, but the answers did not solve my problem...


When my two 100Ah Battle Born batteries in my RV reach 30% SOC, I charge them up with my 2000W generator. However, when I begin the charge, the BMV 712 immediately reads 100% SOC on my phone. Why? Shouldn’t it start counting up from 30% SOC to 100% SOC as the charge cycle progresses??


Thank you!


FYI: After a full charge I have tried setting the “State-of-Charge” to 100%, as well as “Synchronize SOC to 100%”, and tried both on and off for the “Battery Starts Synchronized.” No joy.
