Lightweight AGM != lightweight Lithium-ion. An AGM battery is still a lead-acid battery at heart. Li-ion is a big leap forward in capability at the expense of, well, expense

The battery OP installed is around $1,000-1100 for the equivalent battery. The best application for a street car from voltphreaks is their 9lb 45aH 1200CCA unit at ~$1700. At 52lbs of weight savings, that's not such a bad cost/lb ration compared to the other stuff people do to lose weight, but still nutty expensive unless you're competing with the car or just doing it for fun
