In definition of “virtual battery” there are missing some important properties in the custom nodes like /System/MaxCellVoltage, MinCellID, MaxCellID and more ….
/System/MinCellVoltage is included and working fine.
The “Virtual devices” are a really great feature and it is possible to Configure Virtual Battery as System battery monitor and DVCC battery monitor, so they must have all important functionalities defined.
Unfortunately, in release version FW 3.70 , problem was not yet solved.
