Chapter in this post:
LiPo batteries are used in pretty much every drone and every quadrocopter. Such a lithium polymer battery is susceptible to low temperatures. Even a temperature around freezing point can shorten the flight time by 30 to 50% if the drone batteries are not prepared for the flight. So if you want to fly your drone in winter, then you should consider the following tips and tricks. So in the ideal case you can keep the regular flight time of the drone in wintry degrees.
Drones fly in winter - keep batteries warm
So that the drone and especially its lithium polymer battery does not literally have to start cold, there are various ways to keep it warm during transport and in preparation for the flight. My solution is a kind of document safe for mobile use. The mobile, lockable and fireproof case is also intended for LiPo transport due to its fire resistance. The fire resistance means that heat does not get inside as quickly; Conversely, batteries that have been warmed up at home or in the company do not cool down so quickly during transport. There is one here Document safe / battery case that I bought:

Warm up the drone's battery - hot water bottle or hand warmer
Another tip for warm drone batteries in winter comes from grandma's bag of tricks: a standard hot water bottle. It is only important that you do not use water in the hot water bottle that is warmer than 40 ° C or a maximum of 50 ° C. Because not only the cold in winter can damage the LiPo batteries of drones, but of course too high temperatures and heat. Alternatively, you can several hand warmers and distribute them between the batteries in the bag, backpack or case shown above. The advantage of the pocket warmers: you can quickly grab one to thaw your hands that have become cold from the drone;)
Keep batteries warm and / or recharge on the go
If your DJI batteries fall victim to the cold or do you want to keep them warm by charging them on the way to the place of use, then I have a few recommendations for you. Here in the blog, charging cases and mobile charging stations have already been presented here and there for some DJI drones. Have a look at the corresponding articles on DJI drones and DJI battery charging systems:

Hallo,
In my free time I fly a dji mavic air 2 passionately. I thought about warming up the batteries in the oven in winter and then putting them in a tight box. Unfortunately, I do not know whether it is dangerous to warm up the batteries in the oven. I would be very happy to hear from you.

Hello Kilian! There is no way I would do that. The ovens are not very accurate in the lower temperature range and the lipos should never be warmer than 60 ° C, as this damages the chemical composition. I would rather aim for a temperature around 35-40 ° C and ovens are not designed for that. So rather a box with a terrarium heating mat (like These ones) that you can set and then aim for 35 ° C.
