Keep in mind official "rating" from DJI is for 0 degrees C (freezing).
Flying below that could technically be considered a way to void your warranty, or "Pilot Error" at the least.
That said, it apparently handles quite well in cool temperatures (not too cold). Though condensation is a concern, obviously flying in lower humidity is a good idea. Bigger issue in higher humidity in cold temps would be ice buildup on leading edge of the props causing a sudden failure. Or cold temps effects on the batteries.
Flying in cold does require warming the battery before flight.
Also big issue with returning the mavic indoors for example, after being cold. Like any electronics, has potential to build up condensation all over external and interior surfaces, which could cause damage.
Here is a link to a youtube channel of a Canadian (called Cruising Off Duty) who flew his mavic through the winter, did a fair bit of testing of flying in cold temps:
Cruising Off Duty
Has a bunch of great info in his videos about cold weather flying.
So long story short, it's possible as long as it's low humidity, not too cold, and you take certain precautions. However regardless of how "possible" it is, it may have implications on your warranty with DJI.
