I've flown in temps as low as -15C with a Mavic Pro Platinum and
Mavic 2 Pro, and also well inside the Arctic circle. Standard advice for batteries in low temperatures applies:
- Keep them fully charged and out of the cold as much as possible until ready to use
- Only fit them when actually ready to fly
- Be careful they don't get condensation on when you take them from warm storage to a cold operating environment. Dry them off with a towel or tissue before installing into the drone if so.
You can also count on vastly reduced flight times compared to warmer climes. I was sometimes seeing sub-10 minutes with the
M2P, but ~15-20min was more a typical max flight time for a full battery (the
M2P is supposedly capable of 31min). It's also sensible to have a pretty good idea of what you are going to do before even getting the drone out of the bag to make the most of what flight time you have, so the matra should be
"Plan the flight, then fly the plan!"
I'd also second the recommendation on hovering for a little longer than normal to make sure everything is OK; it can take a little longer to get GPS lock at extreme latitudes so you may need to do this anyway, but since you are outside DJI's official operating temps a little extra time on the health checks is worth doing. Make sure you have your RTH location dialled in properly as well.
Also, be aware that you might get condesation and ice form on the drone while in flight. It's *definitely* worth being aware of the humidity levels and dew point where you are flying to have an idea of how likely this is, or even doing a quick test flight to check the state of the drone when you bring it back.
