I fly in -10c with no problems as long as you take off with a warm battery.
Here is some data from jwt873
When it's 30C (86F) outside, the battery gets up to 55C (130F)
When it's 0C (32C) outside, the battery gets up to 40C (104F)
When it's -20C, (-4F) outside the battery gets up to 30C (86F)
I woke up this thread to comment on some more sub-zero testing I've done.
It was -30C (22 below zero F) this morning so I took a flight and watched the battery temperature.
I left the ground with the battery at 25C (77F).. In weather this cold the battery starts to feel the affects. It only warmed up to 29C (84F).
I did some low speed flying and hovering and it started cooling back to 25C. This is the first time I've seen the battery cool while in the air.
Normally it warms continually from takeoff until the end of the flight.
I put the craft in sport mode and did some high speed flying. The extra current draw took the battery back up to 29C.
Anyway. The Phantom 4 still flies just fine at -30C (22 below zero F). The camera and gimbal perform normally.
But, when it gets as low as this, you have to start watching the battery.
If you do mostly low speed flying and/or hovering in temps this cold, the internal temperature will drop.
Out of interest, flying at -30C (-22F) caused absolutely NO noticeable reduction in flight time.
DJI Go showed this as my 233rd flight. I spent an easy 19 minutes in the air, traveling a total of 5 km (3.1 miles) and landing with the battery charge at 26%.
