http://tinyurl.com/pry3y excerpt from an excellent article: But lithium costs exponentially more. "With a lead-acid battery pack," Wilson says, "if you spend $1,500, you get a range of 25 miles; with nickel-metal hydride, for $6,000 you get a range of 60 to 100. With lithium, you spend $20,000, but [get a] 200-mile range. Lithiums are bitchin', but they're just not really available yet. So everybody's stuck with lead-acid batteries."
