I've never done it, though, and your motorcycle battery idea sounds iffy. You should call your local supplier or a manufacturer.
These babies cost $1,000 and up. I'm not sure I'd want to risk mine near water. In fact, I had to replace mine when it got soaked accidentally by a hydration device being upended into it (don't ask).
