I'm setting up an Erle-Copter & running APM Planner 2 on Ubuntu 16.04. I want to monitor my battery voltage with APM Planner 2.
From the flight data screen, I can see the percentage of battery left, but as I don't know after what percentage I risk damaging the batteries this isn't incredibly helpful, and I'd prefer to know the exact voltage.
Is there any way I can get APM Planner to display the battery voltage? Or, better yet, have it warn me when my battery voltage is getting low? It looks like this supports exists for Mission Planner, but not APM Planner, but I'd prefer not to switch to Windows if I don't have to :P
But when I run APM Planner 2, the voltage is always displayed at 0, even when the battery percentage reports to be %80 - 100.
I had therefore assumed the voltage displayed was the voltage being drawn or something, but sounds like that might not be the case.
Any idea what the issue might be?
I've also tried checking into status tab under info view, but the only battery information is in percentage.
