I agree, you'll be fine riding bareback for a while, I'd check the individual cells every day just to be on the safe side. I have four of these Overkill boards. I call them boards because they look unfinished...like they're supposed to be inside something. Everyone who uses them just finds a way to attach them somewhere and forgets about them. I went high tech and use double sided tape.
One other thing, the folks at Overkill are very responsive to any questions you might have. Of course you can usually get just about anything you need to know here on the forum, but if you want to talk to Overkill, they won't mind at all.
