ControllerCurtis 1231C-8601
Curtis is doing well in this conversion. I barely hear the 1.5khz in the vehicle. Louder outside people say. Very nice slow speed control.
Batteries20 US Battery US-125, 6.00 Volt, Lead-Acid, Flooded
System Voltage120 Volts
ChargerRussco sc-18
SC-18 mounted behind the seat. About 10 hours charge from 80% DOD
Heater1500 watt in stock heater box
DC/DC ConverterIota 45
A real nice converter for the price. No complaints. I leave it on all the time to keep my aux battery charged. Uses almost no current when idle.
InstrumentationWestberg amps,volts. VDO aux volts. Motor over-temp led
Top Speed75 MPH (120 KPH)
Has gone 70, at about 350 amps!
AccelerationPretty snappy for 25 hp!

Additional FeaturesAnderson 350 amp disconnect at rear pack. All electrics housed in aluminum box. Clarion stereo w/4 speakers. I used a relay-activated precharge circuit for the Curtis with the recommended resistor. Added a "precharge confirm" neon pilot lamp to verify precharge and circuit integrity. Takes about 3 seconds from "switch on." Neon light stays on until controller caps discharge below 90 volts or so. I also wired the motor overtemp sensor to a red led on the dash, and used the "start" position of the ignition switch as a test for the circuit. 1500 watt electric heater replaces water core in stock heater.
The truck has been absolutely reliable and has become an almost daily driver to town, 23 miles one-way. Due to highway speeds and large hills, it requires a 3 hour charge to get home comfortably. I get the "EV grin" every time I drive it. Would definitely do it again!
