Too Cold to Fly the DJI FPV Drone? NOPE!

So the manual says not to use the DJI FPV batteries if the temperature is below 14°F ( -10°C ), so what happens if you try to fly when the air temp is -10°F ( -23°C ) and a windchill around -30°F? What's the coldest temp you have been willing to fly in? #djifpv
