MOT_BAT_VOLT_MAX and Min out of limits

ArduCopter Copter 4.0

Hi,

I am setting up a 12S heavy lift following the guide here:
https://ardupilot.org/copter/docs/tuning-process-instructions.html

When setting the Mot_BAt_volt_max/min parameters (50.4 and 39.6 respectivley)

Both these values are “out of limits” according to Mission Planner (maximum value is 35).

In this scenario what is the correct number to put in the parameter?

Ignore the out of range warning and set the parameter to your battery’s actual max voltage. The parameter is not actually limited to anything. When the min/max range was defined for the GCS to check, that was probably not a battery that existed.
