I have an 8S build using a Matek F722-wing and the displayed voltage is always 25.5V. Even when using the iNav OSD to display the battery volatge it will still only show 25.5V. When plugged into my computer the iNav configurator will show the appropriate voltage so I am guessing that this is a limitation of the DJI system itself using an unsigned 8-bit integer for craft voltage.

Does anyone know of a work around?

use average cell voltage

Thanks, that works.

any time
