I had the same thing happen to me, after flying for several months. Brand-new battery separated from Spark, sending them both crashing to the ground. It was only from a height of 40 feet but enough to snap a leg off of my spark. Luckily, my Spark was still under warranty and DJI honored it by replacing the drone with a new/refurbished one. It flies great. They also replaced the battery after I sent them a photo of the broken battery. I should add that they did this all very quickly, and kept me updated via email every step of the way.Very nice! Make sure the battery is secure, my first Spark dropped the battery off in mid flight, bought battery clips on amazon... dji sent me a new Spark... I was crushed when I saw the battery fall off!
