I have the same question.
Temperature below 0C killed my GoPro batteries (all of them). So I am worried about Mavic batteries. But much more I am worried about camera and gimbal. Can I damage the camera or gimbal if I fly in winter? Even misted glass could become a problem if it happens from the inside side without at opportunity to clean it later from stains.
I always check
weather sites before flights but what's your opinion?
