ahh. So, I'd like to use the current battery as the start battery and get 2 new ones to use as a house bank. You know, so, they are the same age same usage same same? And for the next week or 2 I think I'll just do the switching myself and research some more on a better charging setup.

You can feel free to start engines from deep cycle batteries. It won’t hurt them. They are just relatively large and heavy for a given CCA or MCCA ( (marine)cold cranking amperage). My start battery is a U1 size. You can pick it up in one hand.

If you run high current through a deep-cycle battery you may damage the plates. There are batteries that would work fine in both situations (some AGMs), but I don't think you have any of those. Btw. if you go solar, don't skimp on the regulator. Without one or with a cheap one, you can kill the battery in no time. Don't ask how I know. Marek s/v Fennel (C&C 24) Ottawa
