Different voltage between VRM and battery

I have connected the power of a Venus GX on a service battery and also a multiplus. Now I see on the VRM Website (monitor) a voltage of 9.6 Volt but my service battery has 12.5 Volt. Why is there a difference between the VRM monitor and the real voltage of the service battery?

What is the voltage (measured with a multimeter) at the Multiplus battery wires connectors?

In Venus GX, if you go to "Settings" and then "System Setup", what you have set for "Battery monitor"?


And do you have DVCC enabled?

After firmware upgrade to 2609481 and connecting BMV monitor on the Venus GX everything works very nice.
