Want to thank you guys for your feedback.....
I installed the charger directly to both batts, and all is well....i will repost if something fails. I am curious to know what you all do on the 'off season' ......ie. do you just keep the charger on thru the winter when not running the boat?
as a side note the Promariner Prosport 12 Dual charger is actually waterproof as well, which is a bonus. Either way it's in a nice dry area.
