The Swellpro Splash Drone series is literally an all-weather-drone. Whether it fly through the rain or it is sunny. Not even snow storm can stop you from flying it. This video is taken thru the blizzard in New Jersey, with snow up to 2 feet using the Swellpro Splash Drone.
See how the battery worked so well even in extreme cold weather. Not all drones can withstand that.
