|Conversion Cost||$5,000, not counting cost of car, which we have had since 1998. Some parts were salvaged from old fork lifts and friend's used parts. Includes replacement of used, four year old initial batteries with Dynasty DCS100L UPS batteries and now Odyssey TT1370.|
|Car is reliable, low cost, daily transportation for around-town driving.|
I am looking forward to the day when I can install a set of Firefly
batteries (or Lithium) with twice the range and half the weight.
With a heater installed by then, it will be a perfect in-town car.
