Hello,
We are running 2 batteries on our system and I am trying to monitor the Current and Voltage of the 2nd battery on QGC by feeding the output of the BR Power Sense Module to the unused 3.3V ADC input of the Pixhawk. The values I see on the Mavlink Inspector seem reasonable but if I activate the BAT2 monitor on the screen, I only get the default -1 value. Any help or direction would be greatly appreciated. I am including screenshots.

Here is some discussion about using Battery 2 and the ADC pins: Second battery monitor documentation · Issue #154 · ArduPilot/ardupilot_wiki · GitHub
A Pixhawk 2 has this capability with its 2x power ports and I’ve used it before with two battery monitors. CubePilot | Autopilot-on-Module | Blue Manufactured in USA | Blue Assembled in USA | Pixhawk Original Team I’ve never tried it with a Pixhawk 1.
