Voltage sources - yaapu/FrskyTelemetryScript GitHub Wiki
Battery voltage is tracked independentely for 2 battery sources: FLVSS and flight controller battery monitor. In single battery mode a short press of [ENTER] on Taranis cycles between all the sources. Min value is also tracked for the 2 sources and can be shown with a [MENU] short press on Taranis.
Note:If you use a second FLVSS voltage sensor the OpenTX variable has to be renamed to "Cel2"
When a second battery is detected the script also tracks "aggregate" battery values and shows a "B1+B2" label in the right panel. Cell value and battery voltage is the "minimum" between the two batteries, current is summed and capacity percent is averaged. A short press of [MENU] on Taranis or [ENCODER] on the Horus will show min/max values for this aggregate view.
In dual battery mode a short press of [ENTER] on the Taranis switches from single aggregate view to individual dual battery view. Subsequent short presses of [ENTER] in this dual view will cycle between voltage sources. In dual view a short press of [MENU] on Taranis shows individual packs min/max values.
To get back to aggregate view and retain the selected voltage source short press [EXIT] on Taranis.
For detailed info on supported battery configuration please check the wiki
Note:On the Horus voltage source has to be selected from the menu and Min/Max values are accessible by switching to the dedicated screen
