I crashed my bird on the 2nd day of flying it. Went for repairs to replaced the gimbal and camera, flew around with my 3 batteries to test the bird post flight to see if anything has gone wrong. So far so good. No warnings from the drone, or battery or gimbal. However, after a few days of being busy and not flying, i charged my batteries again to prepare for flight and i noticed one of the battery had a rattling sound when it is shaken or moved. I've created a quick video to demonstrate the sound. I wonder if any other owners out there who crashed their drone also experience the same issue and if so, are you still using it and does it give you any problems. NOTE: The sound in the video seems greatly enhanced, it doesn't rattle as loud as the video plays it out to be.
