Guys, Check your local marine supply store (or marina). Ebay is also a good place to watch, but make sure its not crappy one from China.
Guest makes some great battery chargers that can be mounted just about anywhere and the best part is that they are ment for a boat, so they are waterproof!
I'm running a Guest 2608A for my Cobra, the same for my ATV and a Guest 2611A for the dual battery set-up in my trailer.
Go to
www.guestco.com for more information.

The 2608a is discontinued, but it was the same charger as the 2611a but with a single output in a smaller hsg.
Hope this info helps.
