MotorNetgain Impulse9 Series Wound DC
ControllerManzanita Micro Zilla 1K
When I first converted, used a Curtis 1231C
500A controller. It died after about 20k
miles. I replaced with a second 1231C which
died in a spectacular way, shorting the motor
to the battery pack which led to the motor
spinning so fast that it blew itself apart.
So far, all's good with the Zilla!
Batteries45 Thunder Sky 100AH, 3.20 Volt, Lithium-Ion
I put on about 10,000 EV miles on the
car with lead-acid batteries TMX31, but
had to replace the pack every ~3000
miles. I then converted to LiFePO,
losing about 500 pounds, and now have gone
another 30,000 miles with no perceptible aging
in the batteries
System Voltage144 Volts
Previously I used a Zivan NG3. But it failed
after about a year. The service person couldn't
fix it. So I gave up. Now I have a bunch of
24V switching power supplies in series and a
single transistor regulator
DC/DC ConverterIota 50A
I previously had a CCPower DC/DC
converter. But the unit was defective,
and the company would not take
responsibility for it. Not a place I
would recommend!

Conversion Time150 hours for PbA, then ~100 hours to
convert to LiFePO. After the Curtis 1231 died
and took the motor along withit, I got a new
motor and a Zilla 1K. that took another 50
Conversion Costa lot. >$20K, especially after all the
replacements for the failed electronics
Additional FeaturesAmazing battery monitoring / balancing system from
Joulesys. This is the most reliable and best part of the car!
Recently, I installed a vehicle monitoring system from
Joulesys. It keeps track of the batteries, various
temperatures, and one can add a GPS and an accelerometer.

I then upgraded to the new LiFePO BMS system. This one totally
