Better plan on heavier front springs if you go ^ this route! I never knew something that small could be that heavy!Been in the car Audio World for a while now. One battery is capable of doing the same job as a whole bank of lead acid. Limitless Lithium is the brand I’m familiar with.
As far as replacement car batteries I’ve had good luck with my XS Power Group 27. It’s been in my 80 since the engine swap and have had zero issues with it. Truck has been sitting at David’s for months at a time and has always cranked first time every time without being on a battery tender.
