I use 2 AGMs (24vdc motor) in my boat. They out last & out perform lead acid batteries and are way cheaper than Lithium. While the Lithium will out perform the AGMs in run time, I doubt seriously they will out last them by any significant amount. Here is a good write up that compares the two. Which Battery is Best for my RV? An AGM and Lithium Battery Comparison. | Go Power (gpelectric.com)
Lithium = $900 - $1,000.
AGM = $200 - $300 (less on sale)
You can buy 3 or 4 AGM batteries for the cost of one (1) Lithium. I average about 5 to 6 years out of my AGMs on my boat. I doubt seriously that one Lithium battery will last 20 to 24 years.
Also, you will need a Lithium battery charger (more cost) as you can't use a regular lead acid/AGM charger on a Lithium battery without probable damage to the Lithium battery.
If the budget doesn't support the AGMs, then (as packfish suggested) the Wally World deep-cycle, marine lead acid battery is a good choice.
