Are the batteries for the Phantom durable against drops? Had a friend over who was holding the battery by itself, ended up slipping out of his hand, hit a corner on my desk before hitting the carpet floor for about a 3 ft drop. Think I can still trust it to remain fully functional for flights? Upon further inspection and comparison to another battery, there's absolutely no visual damage to the battery, however, there is just a smidge of wiggle room of the cell within the carriage from left to right and vice versa, and I mean just barely, but on the battery that wasn't dropped there is absolutely none. It *may* be that this battery was already like this prior to the drop, but I doubt it. Can anyone confirm whether their battery is 100% snugly secure in the carriage (white shell of the battery that wraps around the gray cell, not the Phantom) or do some of you have a little wiggle room as well? I'm thinking I'm probably fine, I also checked the readings of it on the Phantom Assist software and everything seems good. My only concern would be that an internal connection of the battery could now be loose and at stake while in flight. I'm being really **** about it and will probably just order another battery just to be on the safe side, but I am curious to hear whether you guys think it'd be OK. Thanks in advance!
