The thing is, Yuneec does provide a means to assure the battery is locked in place, but people elect to either ignore it, fail to check it, or just don't pay any attention to what they are doing when inserting the battery. If the battery does not "click" during the installation, it may not be fully seated. If a user can see a gap between the rear edge of the battery and the body of the H, it's certainly not fully seated.
The second sentence is all it takes to eliminate most H accidents and issues.
I'm not suggesting either was the cause of this incident but if more people paid more attention to the flight planning and pre-flight processes there would be far fewer broken H's. The H really isn't a toy, aviation is not a game, and neither should be treated that way.
