I've got a quick question about the battery voltage percentage shown on the HUD of the APM mission planner. My setup is to measure the total pack voltage (option 3) via the onboard ADCs (not using the Attopilot sensors) and the voltage readout is correct. The percentage reading, however, seems to read 100% constantly, even as the battery voltage reduces. Does anyone know how to get this display to function correctly? I assume that I need to set a maximum and minimum pack voltage to let enable it to figure out the percentage but I can't see an option for this anywhere?
