I have a GlobalLink 520 connected to SmartShunt 500A. The SmartShunt shows SOC 100%, but the VRM page with data from the GlobalLink shows 99.7%. The charger is connected and there is no power usage other than the Victron devices itself. It has shown 100% earlier (60 days ago), so this seems to be a new bug.
It has shown 100% earlier, and the “Time since last full charge” has been reset 63 days ago.
That is not happening anymore. The problem is actually not the 99.7%, but the fact that its not stated as “full charge”.
