MinimOSD battery voltage error

Posted by David Pulvermacher on March 15, 2015 at 9:16am

Is there a parameter setting in APM 3.2 that alters how the battery voltage is displayed in telemetry?

Mine's out by at least a volt. Perhaps some sort of calibration necessary? I'm using APM 2.6 and a power module with the Minim powered by a seperate Ubec. Thanks...

    Hi, its edit correction

      Thanks Stuart. I'll try some other values. Best. DP

        cool, you should be able to use the ratio of actual voltage and what you are reading to get you very close. If the reading is low I think the ratio should be above 1.....new Batt_Volt_Mult = actual/telem value x  old Batt_Volt_Mult I think :)....invert the ratio if I got the wrong way around.
