Help. Drone was about 100ft in the air and i was about to land when i heard message "battery level is low - the aircraft will head to homepoint in 20 seconds". My screen was reading about 50% battery level. At this pont i was far away from the homepoint. I tried to land the drone but it kept going away from me and it headed straight into trees. It crashed into a tree and heavy brush... This happened about 45min ago and I was able to recover it. I havent powered it at this point and will be contacting DJI. Is this usually covered under warranty?
