[QUOTE="hispls, post: 8662141, member: 614752"] I don't believe there are any LTO batteries for retail sale yet but I'd be shocked if someone isn't working on tooling up a case and bus design. You could DIY LiFePO4 for about half the cost if you wanted. Really the "markup" over the cost of materials is pretty fair if these companies are trying to run a business and offer warranty support. You would probably do fine with just 40AH size for LiFePO4 BUT you definitely would not want to try to add a second alternator to that. AFAIK that size LiFePO4 runs 1000-1200$. Really not too far out of line for what you'd pay for enough AGM to hold the same voltage real-world and saving loads of weight and space. Life expectancy should be a bit better for any lithium than AGM so unless you get really unlucky you do save in the long run either way I think. That said if you live in a place where it gets extreme cold you might avoid LiFePO4. Their ratings really go down the toilet below freezing. Personally I'm really stoked with performance of the LTO cells, but it's a bit more of a commitment and DIY only sort of option. [/QUOTE]
