    1) if I disconnect the 12V battery, will I lose the data for the little monitor on the dash?

    2) how the 12V battery get charge? from the HV battery?

    thanks.

    To further fellow Australian Feri's answer above, the 12v auxillary battery receives charge via a DC-DC converter within the inverter (i.e. 144v to 12v).
