not for a boat but on one of my motorcycles i put an antigravity lithium-ion battery and when it senses a constant drain like over winter it shuts off. in the spring there is a button switch you depress and resets and you have a charged battery.
I put a li-time in my 36 volt cart that is used to putt around the camp ground. If I remember right it was about $600 with a charger. Seems to work well for that purpose.I have a 48volt golf cart that takes 8 6 volt batteries, that is a $2,000 bill every 5-6 years.
Would this new lithium ordeal fix this sonofabitching expense?

UPDATE. I bought the 36v 100ah for my ulterra. 36v 21ft nitro. Absolutely awesome, I would charge every 3-4 trips but only because I felt like I should. I don’t think I ever had it below 20%
I also got a 12v 100ah to run my 3 graphs and livewell on. I would go with the 140ah for that so I could run 3 full days instead of 2. Overall Im happy with them. Now the biggest question will be, to see how they survived the winteI take it you bring them indoors?

Couple hrs of removal time is worth it for the investment and piece of mind.I take it you didn't bring them indoors?
I was hearing conflicting reports so I took mine out of the boat..pain in the ass. If I could leave them in the cold storage garage though I sure would. Especially now that I am running 5 of the things!
