I have seen some lightweight lithiums too while looking around for a new battery since my current 3-year lead acid is on 4 years and losing its grip on this world... but my sense was I would get little reserve capacity and/or weak cold cranking power. The Optima AGM yellow top has capacities I need but it's not as light as you hoped. Unless I am missing something it is 26 pounds in its lightest version, but I did not find lithiums on Optima's site, just sealed lead acid.

Know a supplier?

That leaves:
Optimia AMG (yellow top since that is what I plan to put in my diesel suburban next)
Lithium
I plan on relocating it under the back seats (lots of cutting and welding).
I know the optima weighs about 43lb, I handle them almost ever day at work. The bigest lithium battery weights 5lb I think.
35lb+ of weight loss and more room up front is very tempting.
