72v motor
DrivetrainWas a 4-cylinder gas engine,
now chain
driven electric motor
ControllerAlltrax SR72300
Batteries10 Nissan Leaf 2nd Gen, 8.20 Volt, Lithium-Ion
10 Nissan Leaf either 1st or
2nd Gen
batteries, 2 packets,
nominal 4.2v each
System Voltage72 Volts
Top Speed55 MPH (88 KPH)
Have hit 55 mph on fairly flat
Range35 Miles (56 Kilometers)
Kind of hard to tell. Have run
as low as
1.25 v for 7.6 miles to 10.5
volts for 8

Theoretical is up to 58 miles
if the
battery discharge curve were
linear but
range various under commute
route and
driving style. Current work
commute is
right about 32 miles as a
round-trip to
work will leave the batteries
0.5 v above
the low voltage cutoff under
Previous commute for equal
distance would
leave the batteries at 13 v
above the low
voltage cutoff under load.
Watt Hours/Mile100 Wh/Mile
roughly 100 whr/mile in basic
commute to
work. can vary based on head
wind and
outside air temperature (better
when 100 deg F or less than 104
deg F and
EV Miles
Start:19,884 Miles (31,993 Kilometers)
Current:22,124 Miles (35,597 Kilometers)
Total:2,240 Miles (3,604 Kilometers)
    As of 7/9/2022
Seating Capacity1
Conversion TimeStarted in December 2018. First
street test
ride in April 2021 due to
putting project
Conversion Costroughly $800 for batteries,
$1050 for
motorcontroller and motor,
probably another
$500 for just electrical
including wiring
mileage varies, as expected. have gotten as
much as 6.25
miles/volt and as low as 1.25 miles per volt
depending on
speed, uphill slope, windy day, etc.
