I have the MRT-3000 UPS and try to get real battery voltage through USB. USB protocol reference has specify for battery.voltage: report id | Usage...

That makes sense to me. The field needs to be split into bytes. The low byte is the integer part of voltags, and the high part is units of 10 mV. And this is per cell. Probably the unit is measuring the total and then dividing by 36. But volts per cell will have the same interpretation for varying cell counts, so it's a nice representation.
