Winter is great time for capturing aerial photos and videos. One of the challenges is how to keep the batteries warm during winter flights. The drone manufacturers sell battery warmers, insulating pads etc. If the battery is too cold the drone wont take off, and even worse, cold batteries might lead to sudden voltage drops while flying, which in a worst case causes the drone to fall out of the sky.

One of the best ways I have found is to keep batteries fully charged and warm before the flight. Keeping the batteries warm is as easy as storing the in a small thermo bag together with a bottle filled with boiling hot water. This way the batteries stay warm and cozy, after the days job you can even warm your frozen fingers using the hot water bottle
