dual battery w/isolator and solar charging

[496bb]

So, looking to put in two fresh batteries and make a dual setup. I have a diode isolator. But, I see these Cyrix isolators, and I'm trying to figure out how I could wire in a simple cheap solar trickle charger to keep both batteries topped off, as this won't be a daily driver. Anyone done this?

Maybe make your life easy. New Volkswagons used to ship with a solar battery maintainer installed,so dealers never had a dead car on the lot. Dealers removed them before sales. They suction cupped to a window and plugged into a cigarette lighter,dealer techs used to peddle them on ebay for 10.00 I bought one there but it's been years. Maybe still a thing,maybe not but easy to check. Just looked on ebay not cheap anymore I snapped you 2 screenshot 1 so you'd have specs.
