This puzzles me. I don't see what, other than scarcity, makes NiFe batteries so bloody darn expensive. OK, nickel isn't the cheapest metal, but I'm seeing over a buck per watt- hour (~$1.06) from one US manufacturer. Unless my math is totally off, that's almost 3 times LiFePO4's cost per watt hour ($0.37), and about 14 (!) times lead's cost per watt hour (C20/$0.076). Maybe I'm missing something, but I don't see anything to justify that price other than limited production and "because we can."
