Widget to display the levels of Lipo/HV-Lipo battery with mAh Used based on battery voltage from 'Cels' sensor (FLVSS)
If you've ever wondered what % of your battery was left and how much mAh you've used
This widget will display them based on the lowest cell from the telemetry obtained from the (FLVSS).
- This is not an "Actual" reading of the mAh. It is a calculation based on the remaining volts of the battery.
- "Actual" mAh consumed can only be obtained from a consumption sensor.
The mAh is based on the Lipo discharge rate of commercially available sensors.
The % listed is based on full 4.20 or 4.35 volts/cell represented as 100% and 3.0 volts as 0%
The live readings are taken from the lowest cell of your pack while connected.
The % and mAh numbers typically rise after a flight since the load is reduced and the battery settles.
Download the release BattmAh.zip
Extract the folder to the WIDGETS folder on the SD card
Select the Widget from the screen
Options available
- Setting the sensor Choose 'Cels' or the calculations will be off
- Setting the Capacity of the battery
- Setting the number of cells (this is for a visual indication of the battery you’re flying and has no effect on the calculations)
- Setting the voltage of the cells in the pack. There is a different chart for 4.2 Lipo’s & 4.35 HV-Lipo’s
If you prefer to use a calculted sensor as I do, it eliminates alot in internal lookups and makes it easier to install into existing scripts
