QGC4.1.2 wrong battery percentage 12s

Hi Guys,

we have recently upgraded our qgc to 4.1.2 but the battery percentage calculation seems to be wrong for 12s. The battery is showing 100 percent even on very low battery.

downgrading QGC to 4.0.2 solves this problem.

Is there anywhere in the code we can edit the formula to solve this?
