Look at LiTime’s 12v140ah duel purpose battery. I think it’s 400 dollars. But they go on sale allot . You might get it cheaper! There’s a utube channel you Might want to watch Goodman fishing . He is an electrical engineer who almost uses LiTime exclusively. Also there are Lithium battery nerds that break the batteries down and check their quality, efficiency and safety! I have not tried a LiTime duel purpose yet myself . But I purchased a LiTime 12v140ah Trolling Motor Bluetooth battery for my smaller boat and I love it so far ! Lots of Anglers are using there products without issues . But like everything stuff breaks lol….. Even the 800 dollar lithium’s. Check it out and do your personal research.
