The NiMH batteries that propel the Toyota-built EV over 100 miles on a charge are, of course, unavailable on the open market. (Wikipedia has an entry on the much-debated "Patent encumbrance of NiMH batteries.") Using lead-acid batteries, this car has less than half that range. But as GM keeps hammering home with its Volt commercials, the average car drives under 40 miles per day. This conversion's claimed range is over 40. The lead acid make this EV affordable compared to the $50,000+ RAV4 EVs that pop up on eBay from time to time. The Buy It Now price is just $22,000.
