Vehicle

1970 Datsun 521

Motor

Advanced DC Series Wound DC
6.7 ADC 8 brush. Salvaged from a forklift
pump motor. My 16 year old son and I
spent 2 days during spring break 2007
rebuilding this motor at Jim Husted's
shop. Click on the WebPage link above to
see the motor being built.

Controller

Cafe Electric Zilla 1K
Currently running at 96volts and 1000
amps. My Logisystems controller finally
gave up the ghost and I was able to
purchase a lightly used Zilla 1K which is
what I always wanted for this truck. The
Zilla's were out of production when I
bought the Logisystems controller.

Batteries

4 45 Volt Chevy Volt Modules, 45.00 Volt, Lithium-Ion
Two strings of 90 volts in parallel.

System Voltage

90 Volts

Charger

Chinese Lithium bike battery chargers
I custom ordered 4 - 6 amp CCCV chargers set
to 49.8 volts cutoff (4.15 volts per cell)
from chinagreentime@gmail.com.

I also have two SE 1072 Shumachers that I have
been using for years.

Heater

2 cheap 120v ceramic cores from space
heaters wired in parallel. They draw about
22 amps total which works out to roughly
2000 watts of heat.

DC/DC Converter

Meanwell SD-500H-12

Instrumentation

HB 404 DC AH Meter

My Evision is glitching and no longer reads my
pack voltage correctly, so I have replaced it.
All other functions still seemed fine.
Evision
I have one of the first units from
www.metricmind.com. It is a very high
quality EV specific instrument. You should
seriously consider getting one.

Additional Features

I originally built this with an Alltrax 7245 72 volt 450 amp
controller. The performance was adequate, but the Logisytems
controller makes it quite peppy and a lot of fun. It's higher
voltage limit also allowed me to stuff a few more cells in my
battery boxes. 90 cells are as many as will fit which raises
me up to 108 volts.

Now I am onto a Zilla which is great and the pack has been reduced
back down to 96 volts which still gives me plenty of performance.
