 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 :)

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

    if(BAT_AUX_DV_CHANNEL > 0 && armedOnce && armed != 0 && last_Bat_Aux_Val != AuxChanVals[BAT_AUX_DV_CHANNEL-1]) {
      last_Bat_Aux_Val = AuxChanVals[BAT_AUX_DV_CHANNEL-1];
    }
    if(start_time > 0 && (millis() - start_time) > 2000) {
      unblock_bat_DV = false;
    }
    if(unblock_bat_DV && (save_bat_warning || (armedOnce && armed == 0 && BAT_AUX_DV_CHANNEL > 0 && last_Bat_Aux_Val != AuxChanVals[BAT_AUX_DV_CHANNEL-1]))) {
      if(!save_bat_warning) {
        cleanScreen();
      }
