 To turn the this feature off, set BAT_AUX_DV_CHANNEL = 0;
 To turn the battery warning off as well set bat_mAh_warning = -1;
 In a future version I will probably replace the mAh adjustment with a OSD menu entry - stay tuned :)

               writeBatWarning();
             }
           }
           // switch armed => disarmed
           else {

      OSD.print( "new bat warning mah:" );
      OSD.setCursor(8,8);
      static char mAh_Warning[30];

      }
