TX16S: displaying the battery level on OpenTX & EdgeTX – percentage [%] and value [voltage]

This video is a short tutorial that present two ways to display the battery level on a TX16S transmitter running OpenTX.

1. In this video, I have Li-Ion. If you search the net, they consider that 3.0V must be the cutoff at room temperature. But, you go to the outside where can be wind and low temperature - the winter is coming 🙂. So, I decided that to take a more conservative value of 3.2V. I have 2 elements, so I choose 6.4V.
2. If you use a Li-Po battery, the voltage must not be below 3.5V per cell. Even so, many recommend not being below 3.6V. In conclusion, if you use Li-Po use 72 as a minimum value.
