On Amazon, you can get 20 Tenergy D-cells for 97 before tax (16 pack + 4 pack), and then configure them 10S 2P for 12V and 20Ah. This is a little bit less money than buying 4 unknown brand 20Ah lithium iron phosphate batteries (which have limitations on cold weather usage). Alternatively, you can buy no-name batteries for half that price on Aliexpress, or used batteries out of Prii.

A little bit more expensive than lead acid, but it should last longer.
I'll pass that Tenergy d-cell to my younger brother for his EV car kit project. The current lead acid battery didn't last long. He'll be back to that project after we finished installing the bumper and winch on the Wrangler this weekend.
