@zurk has the most recent experience and feels this plus a sterling charge controller is the way to go https://amzn.to/4deOydr # ad. Dakota lithium starting.
I have a lithium for my house on my camper and I’m a fan.

Interstate. Had my last set 8 years and they were still working well. Only changed as a precaution this year. I never even had a trickle charge on them over the winter ever. Fully charged them up when I parked boat in Nov then did a full charge in May at beginning of season. I think I paid approx $250 for the starting/house battery each. Also, add the Blue Seas “add a battery switch”. It’ll make everything simpler for charging.

I too did well with the green top battery in the past.

I jumped online but couldn't see them anymore? Have you seen them at the warehouse recently? When I was last looking a couple years ago they only had the marine post agm online for a 24/27 size, I have a size 34 house battery agm from costco but had to go Canadian tire for starter agm with marine posts.

Smart chargers have a "repair" mode on them now. May bring back a severely depleted battery that won't accept standard charge cycle.

I picked up a canada tough from trotac - starts my df350 and df20 no problem. Cost was reasonable and good warranty. I know a lot of people are doing the lithium but I am not drinking that cool-aid yet. The cost of a sealed lead acid is peanuts in comparison- my 2 cents.

If you're suffering buyer's remorse, I'm sure one of us would help you out.
PS. Congrats on the new boat

The big benefits are seen more on a large house bank that’s being depleted quite a bit, charge time is much faster with lithium not a big concern on most sport boats until you do a lot of anchoring.
Need to go into local store the online for this is no good.

I got a group 24 Energizer AGM from Cosco at the beginning of the season. They didn't have the marine version - just clamp-on automotive posts, no threaded posts. I bought adapters, and so far its been great. Lots of juice and no issues starting. Battery was $249, but with taxes + enviro, closer to $290.

X2 for Interstate if your just doing the normal stuff without overnight stays etc to drag batteries down. Just replaced my start battery after 10 years with another Interstate as a precaution. It was still starting my engine fine. Left my house battery in as it’s still doing its thing. Congrats on your boat.

I used Interstate for years with no problem in my Campion Explorer. I also replaced the batteries regardless every 5 years.
For your system you should get 2 identical batteries Probably group 24 or 27 deep cycle as you really don’t need a dedicated start type battery. I have been told in a simple charge system both batteries should be identical otherwise they have different charge characteristics.
In my Commander I use Interstate for the diesel start batteries and 4 Rolls 6 volt AGM golf cart batteries for the house but I also have separate chargers.
The Rolls AGM’s are amazing batteries.

How do you turn it off when it encounters thermal runaway?

Just do both. Biggest that fit.

BMS. Better than unmanaged deep cycles venting sulphuric acid IMHO
