APM 2.8 Battery voltage is 0

Hi. I’M using apm2.8 with a power module. Battery voltage is 0 in both mission planner and mavlink system status message. How can I solve this?


I haven’t ever worked with the old apm2.8, but in my experience once you’ve selected what to monitor (voltage and/or current) and a power module type, then you need to reboot the vehicle before any of the readings or further settings take effect.

Carefully check the output from the PM.Sometimes they get reversed (from the factory) and most are aimed at a Pixhawk nowadays.

Also set it as “other” in the drop down,not as 3DR.

Thank you. Configuring power module type worked very well.

Now you need to calibrate it…
