Weight saving battery technology experiences

Lithium Iron Phosphate LiFePO4 or variants thereof. Not some of the other Li Ion technology like Lithium Cobolt LiCoO2 or exploding laptop battery version. Anyone heard of the technology? Anyone applying it for marine uses? What manufacturer/s? Advantage is it claims to be half the weight of an equivalent 800Ah AGM/Lead acid configuration? Looking at this for a cruising cat in S pacific/Australia area. Charging via Solar, Wind and Honda portable Gen set. Not much alternator charging from dual outboards.

Lithium iron phosphate battery - Wikipedia, the free encyclopedia
Developed at U Texas, and improved with MIT technology.
LiFePO4 cells have higher discharge current and do not explode under extreme conditions, but have lower voltage and energy density than normal Li-ion cells. Used on the One Laptop per Child project and also on some hybrid vehicles.
