Hi,  
I am using a Pixkhawk 4 mini for making a quad copter. As soon as i burn the firmware from Qground Control(stable,beta,developer version), The QGC Pop’s out a notification and tells that a parameter is missing, Once i close it, I get an another error message stating " **Parameters are missing from firmware,You may be running the version of firmware QGC does not work correctly or your firmware has a bug in it. Missing Params: 1:BAT\_V\_CHARGED,-1:BAT\_N\_CELLS,-1:BAT\_V\_EMPTY,-1:BAT\_V\_CHARGED"**

I tried installing different versions of QGC, still the same issue persists with firmware’s.  
Kindly help. Thanks in advance
