2 In place of the radiator. 3 Over the motor, thus the hood
scoop for clearance. 7 in the hatchback area. 6 in a box
where the gas tank used to be. 1 in a box where the spare
tire was with the charger.
System Voltage144 Volts
ChargerQuick Charge Select-A-Charge
This is mounted in the rear and connected via the gas cap.
It's not as fast as I would like, but I don't really need faster.
It completes a charge in 12 hours after 30 miles of driving.
HeaterNone yet
DC/DC ConverterIota DLS-45
I tried a Vicor power module, but it blew 2x probably due to
voltage slew near the rated power.
InstrumentationVoltmeter and Ammeter. Still trying to decide what else I

I built a battery monitor system from plans from James May:

It works very well, and now I can see as my batteries fade
Top Speed65 MPH (104 KPH)
Usually I drive city streets, max of 45. Expressways around
here are 50 and it does that well.
AccelerationPretty close to stock
Range33 Miles (53 Kilometers)
I haven't had a real need to go further. I suspect 50 would
be OK as long as I'm not doing 65
Watt Hours/Mile18000 Wh/Mile
I average around 35 MPH on city streets. It can get on the freeways fine. The furthest so far has been 9 miles at 65 Mph. With 20 miles max that day

Current:145,120 Miles (233,498 Kilometers)
Total:925 Miles (1,488 Kilometers)
Seating Capacity2 adults
Curb Weight0
Original weight was 1860 lbs. I need to weigh it to get
current weight
TiresUpgraded to 14" rims. 185 60 14
Conversion TimeElapsed time 9 years! In reality when I got serious about 6 months. I removed ICE stuff 9 years ago. I didn't really start seriously until March of 2008. I drove it the first time in Sept 2008.
Conversion Costaround 10K so far. It still needs a paint job
Additional FeaturesI put solar panels on the roof of my house, fed back to the grid ( So
charging is essentially free!

I upgraded the front steering knuckles with '87 Acura Integra knuckles, and replaced
the brakes and rotors with Acura parts, giving me about 20% more surface area for
braking. It stops on a dime now.

Rear springs replaced with Acura Integra springs, put the car back to original height
with batteries installed.

I average about 25 miles a day. I can charge at work if needed.
Thanks to Steve McDonald for insight and motivation.

Californians, beware! I tried after a year to get a carpool sticker, since EV's qualify. Turns out my car was registered as a hybrid, there is no way for a DMV office to change it to electric without a certification from a Bureau of Automotive Repair GOLD station. So now my car's registration is in limbo until I get that completed. Doesn't cost much, $8.25, but there are only a few "GOLD" stations around. I should have left things alone!
