This is the sort of conversion I was interested in trying eventually. Big batteries at a high voltage for some real distance and highway speeds. This place has forced me away from these and looking more into supplementing bicycling with hypermiling and ecomodding a gasser instead (or a scooter/motorcycle with a gasser if the area I land in after this May doesn't permit daily bicycle riding). This big conversions don't do anyone a favor for the wallet right now and are quite the time sink in comparison.
Still, this car is wicked cool
