Battle Born LiFePo Batteries

About every six months I check to see what is out there for batteries as I really want to replace my 2 80AH Lifeline 6v in series that are wired up in the bed of the truck. Recently just noticed this as one possible option and the price isn't that far off.

Seeing as how these batteries are able to take a charge so much faster, I'm wondering if it is possible to eliminate the generator entirely and charge straight from truck? I already have an after market 80 amp alternator installed from the previous owner. Taking out my genset and batteries could free up 300 to 400 lbs I'm thinking.

Anyone else looking at these?

"Price isn't that far off."
WHAT??!! Nearly a grand for one (1) 100Ah battery. That 10 times what I pay for one at Costco.

"I have an aftermarket 80 amp alternator"
That is not a hefty alternator. Mine is factory optioned with 220 amps plus there's an option for a second alternator for 440 amps total. (I didn't go with that) The standard alternator is 180 amps I think. I didn't think they even made alternators as tiny as 80 amps any more. Not aftermarket anyways and not for a truck.

Unless there is a really compelling reason to loose 160 pounds (2 batteries at 60lbs each and a 1000 watt genny at 40 pounds) an replace it with 2 batteries at 30 pounds each and a REAL alternator at 20 pounds (total of 80 pounds) net weight lost of 80 pounds, I think it's a waste of money to go with Li batteries.

Net difference in weight 80 pounds. Equivalent to 10 gallons of water. Can you just not fill your fresh water to full before departing and fill once on site?
