I can't speak for your specific drone, but I have experience with electronics and cold weather. I would definitely store the batteries in the warm, and check the manufacturer's guidelines for the correct storage voltage (for a LiPo I think this is about 30% to 40% charge, or 3.85 volts per cell) It also doesn't hurt to store them in a fireproof container ...


The first step I take to help protect my gear from shorting out from water is to apply silicone conformal coating to all the electronics I can. I cover the ESC, flight controller, vtx, and any other exposed electronics. I find that this also provides some protection from random solder drips or conductive grains of sand. However you have to be very careful ...


Storing drones during the winter Should be of little trouble for you. I would recommend that whether you store them say in a garage of in your home, the place of storage be dry and not humid and somewhat warmer than freezing. Batteries should be stored in a somewhat warm environment which again should not be humid, in order to avoid any thaw/freeze cycles ...


As mentioned a conformal coating is what you need. There are various types and methods of application. I haven't personally used this product, but it does look like the best and easiest: Other options are more standard electronic conformal coats which you apply with a brush or spray (hint: spray gets really messy, get the ...


Just to add some extra info to the other good answer, there are liquid products specifically for coating PCB's. They come with a small brush for easy application and you can easily solder through the cured layer should you need it for maintenance.


The electronics will be fine if they are dry, and liPos should be able to be stored below freezing. It is, however, important to let them warm up before charging or using them to get the full performance.
