After 10 months and >2000 miles of Lead Acid, one battery
started failing, so it was time for a lithium upgrade.

Redid the battery boxes from steel to aluminum. Lost
250lbs in weight, and more than doubled the range.

AGM accessory battery.
System Voltage144 Volts
ChargerElcon 1.5KW
I went with an onboard "emergency" charger and have a Zivan
NG3 offboard.
HeaterCeramic. I gutted a small 1500w space heater I bought on
ebay. When it was lead acid, it was useless. I considered
alternatives, but in the end I kept with ceramic and hooked up
more elements. It draws 13A when on and works a lot better.
DC/DC ConverterZivan NG1
InstrumentationE-xpert PRO
Cheap digital voltmeters to show 12V and Pack Voltage
Analog ammeter in the dash
A couple of "idiot lights"
Custom BMS. Real time voltage monitoring, J1772 and charger
Top Speed70 MPH (112 KPH)
could go faster
Range50 Miles (80 Kilometers)
Perfect for my daily commute (12 mi round trip), and in-town
EV Miles
Start:87,132 Miles (140,195 Kilometers)
Current:91,000 Miles (146,419 Kilometers)
Total:3,868 Miles (6,223 Kilometers)
    As of 7/19/2013
Seating Capacity2 adults. Both the trunk and the spare tire were victims of
the conversion.
Curb Weight2,850 Pounds (1,295 Kilograms)

Stock curb weight is around 2700lbs. Redid both front and
rear springs for the lead acid. Now it rides way too high,
especially in the front: will redo the front springs (again).
Conversion Time18 months - first conversion
14 months - upgrade to lithium
Conversion CostDon't ask.
Additional FeaturesClutchless design. Takes a little getting used to, but the Fiero transmission is pretty
forgiving and I can easily shift in less than 2 seconds.
