A strange situation has happened today.
In May, I received a new drone from a warranty replacement after gimbal overload problems. Today, after taking off, I flew about 20m to a height of 15m, I started ActiveTrack and while changing the tracking settings I looked up and suddenly the drone fell to the ground uncontrollably, the battery does not respond at all to turning on, after connecting to the original charger, the battery still does not respond and the charger lights up solid red light.

Recently, there have been problems with the range, perhaps from the controller, and besides, after today's accident, the gimbal is damaged, it does not hold the horizon and front left leg is broken. Should I send back the drone, damaged battery and controller for warranty?
