Vehicle2000 Chevrolet S-10
MotorAdvanced DC FB-4001A Series Wound DC
DrivetrainStock, except for the lack of engine ... 5spd with clutch
ControllerFirst Pick Electronics LLC MaxForcer SL
48-160 VDC systems (200 VDC max), 1000A controller by First Pick Electronics LLC

Programmable parameters such as:
- max. motor amps
- max. battery amps
- max. motor voltage
- max. battery voltage sag
- idle voltage
- rpm limit (if speed sensor is used)

Data-logging and parameter setup done via RS232/PC
Batteries26 US Battery US2200, 6.00 Volt, Lead-Acid, Flooded
2 in the front 24 in the bed, 232 AH (20 H rate), 63 lb each
System Voltage156 Volts
ChargerZivan NG3
230VAC input, configured for 156 VDC lead-acid pack.
HeaterEl. heater installed in the AC core
DC/DC ConverterZivan NG1
Had to upgrade mosfets and change/add capacitors since the original voltage rating of 160VDC wasn't high enough to work off of the battery set that gets charged to about 210VDC (equalizing phase)
InstrumentationVoltmeter for battery pack,
Ammeter for battery pack amps
Ammeter for motor amps
Tach - rpm signal coming from the controller
Dash light - status codes coming from the controller
Top Speed85 MPH (136 KPH)
Could probably go a little faster but doesn't feel comfortable in a truck with over 180K miles
AccelerationGreat at low end, tapers off at higher speeds as the controller is programmed to limit battery amps at 500 ADC and voltage sag at 115 VDC. If opened up it will keep pushing hard, but I don't want to kill the batteries just yet.
Range35 Miles (56 Kilometers)
Actually, the range varies from 25 mi to 45 mi depending on how it is driven and how deeply I allow batteries to discharge.
EV Miles
Start:181,000 Miles (291,229 Kilometers)
Current:184,000 Miles (296,056 Kilometers)
Total:3,000 Miles (4,827 Kilometers)
    As of 9/7/2011
Seating Capacity3 adults
Curb Weight5,000 Pounds (2,272 Kilograms)
Conversion Timetoo long
Conversion Cost$11,500-ish
Additional FeaturesPower steering - original PS pump runs off of the motor back-shaft - a little tricky to use when there is no idle, however, when controller is programmed to provide idle, steering feels very similar to one with ICE
I bought this truck (already converted) in June 2010. It was a 120VDC system with Curtis controller. Since then I
- upgraded to MaxForcer SL 160V/1000A controller
- added a box for 6 more batteries (in the truck bed) and installed a new 26pc US2200 set
- added a set of leaf-springs in the rear suspension
- replaced original rubber engine mounts with custom-made solid mounts (to prevent motor/trans from twisting under high torque)
- upgraded Zivan DC-DC converter to take voltages slightly above 200VDC
- upgraded Zivan charger to one that takes 220VAC and charges 156V set
- added shunt/ammeter for motor amps
- added speed sensor to the motor, fed the signal to/through the controller and added a tach to the dash
