Battery monitoring issues on VOXL2
-
Good day
Could we please be assisted with out battery monitoring on the VOXL2? We have 2 batteries, and accidently overcharged the one. We were surpriesed to see that QGC was giving a reading of 0%, and only later realized that the drone won't take off because one of the cells was dead.
We have since stopped using that battery and are using another, but voxl-inspect-battery on the VOXL2 still reads 0%, although we can fully charge this battery and fly around with just fine.
What could the issue be here, and how could we remedy this battery monitoring issue?
-
What does PX4 / QGC say your battery voltage is? Are you using the APM to monitor voltage and current? We haven't had any issues on our end with battery monitoring

Good day
Does anyone have any idea what the issue here could be? Because the battery % will not show, QGC won't give us any information about the current battery level.
Not long ago, I was running some offboard mode test code to autonomously "fly" the drone with the propellers off. While the code was running, everything just stopped without warning, but the onboard PC and GPS module were still on. Unplugging the replugging the battery revealed that the battery is probably low. If we were flying-flying, this could have been an incident.
Any assistance as to why the drone won't read the battery state and send it to QGC will be appreciated.

@TPSetati What is in the Mavlink messages going to QGC? Take a look at the Mavlink inspector tool.

@TPSetati This is showing that you have a 4 cell battery with each cell at 3.125V which is pretty dead. Do you really have a 3 cell battery?

I have a 3 cell battery. I just looked at the vehicle settings in QGC and I see that the battery settings were set to the 4 cells. I changed it accordingly and the battery percentage now reads an acceptible 94%.
Thank you.
