Drone Battery Voltage

Is there any way to fetch the battery’s voltage from Ground SDK?

I don’t see voltage exposed there. Is it perhaps only exposed internally?

Indeed, you get the charge % only.
we do the calculation internally based on the chipset of the battery.

The current SDK metaframe doesn’t provide voltage information.
