I think I'd buy a real charge controller.
It looks like it comes with an adapter to let you hook up two bare wires. It all looks pretty cheap, like something I would have bought as a kid from Radio Shack in the '80s.

They might have something really nice if they put some 10 gauge wire on that and made it a 20 or 30 amp adjustable bulk charge voltage portable controller. 5 amps is mouse nuts.

I believe this is a matching set of plugs for that. 5.5mm set
