Hank

  I went with a Battery Tender .I think it works about the same as yours
When I started this project last Fall My intent was to redo the enter system
but that plan has changed to just adding the Battery Cables this spring
.I'll look at the rest of it as the session goes by .I can always add ..
Battery Switch .. Circuit Breaker...  Link 10 Single Battery Monitor.. New
Electrical Panel ..

  At this point  I'm thinking of mounting the charger by the front battery
and run it off of the 110 v plug in the Head. Putting the Switch and Circuit
Breaker under the seat and mounting the Battery  Monitor some place were I
can see it Not sure if that will be out side in the Cockpit or in the Cabin
like Fred 's

  Keep in touch
