was initially estimated at $3000-
3500/year in fuel alone, not including
maintenance savings! Those numbers
based on fuel costs of $3.75/gal.

Inlet" behind the gas cap cover.

out about 2100W on 144V. Also lined the
floor and panel behind the seat with
radiant barrier.

55Amps @ 13.6V. This unit is
configurable with a jumper to output a
dual-voltage, 14.2V during vehicle use
and 13.6V when the vehicle is off.

Top Speed85 MPH (136 KPH)
This is the max on the speedometer. It will easily go a hundred if I tried. It would do 85 with the lead and original controller.
AccelerationAwesome! Will spin the tires!!!
Range110 Miles (176 Kilometers)
Range was calculated driving fairly easy. With interstate driving speeds the range is probably around 85 or so if not using the heat but I usually keep it around 55-65 or so.
Watt Hours/Mile399 Wh/Mile
399 is based on power from the utility averaged over a month of driving with heat and lights at times and pulling a trailer maybe 10% of the time. Not bad considering the trailering!

This is our company errand vehicle and my commuter. Doing our little part to reduce pollution around Spartanburg, SC and our dependence on foreign oil.

I hope to do a full size van when the battery technology becomes affordable with AC drive and no transmission!

Since upgrading to Lithium batteries I'm using it a ton more. Due to losing several hundred pounds in the upgrade, I've added a trailer hitch to haul stuff on my small trailer as well.
