Geeft Percentage van Lipo weer, van enkele spanningsbron

Widget beschikbaar voor alle afmetingen van telemetriepanelen

Selecteer de spanningsbron.

Moet een enkele spanningsbron zijn zoals VFAS, A1, A2, EscV (Neuron), enz.

Selecteer het aantal lipocellen voor een correcte berekening.

Bewaar onderstaande code als: main.lua

En kopieer het lua-bestand naar de SD-kaart in de widgetmap met een aangemaakte map met de naam: BattPct
\widgets\BattPct\main.lua
