It’s definitely not used when it’s raining. Of course, there is no risk, even your batteries can upset you when you least expect it in such weather 🙂
Yes, your drone will not work if your batteries are below 14 degrees, for this, if you have a DJI series drone, there are stickers for you to stick on the battery. In such conditions, we arrange a suitable place for our batteries in the back seat of the car and take off our jacket 1-2 hours before the shooting point from the air 🙂 It happened that you did not bring the batteries to the appropriate temperature beforehand, it is not right to expose the batteries to sudden heat, to keep them at high temperatures like an electric stove! Be sure to take care to bring it to the appropriate temperature in an environment that is not too hot.
