Vehicle2006 Kawasaki EX500
Donor Bike: Kawasaki Ninja 500R
I'm an engineering student, decided this would make a good project;
once I got started, I didn't stop until it ran. I think. It was 2 months from
when I decided to start a build to the test run.
MotorMars ME1003 Permanent Magnet DC
ControllerAlltrax AXE7245
Batteries11 Nissan Leaf modules, 4.10 Volt, Lithium-Ion
I am using 11 lead modules for the drive system and 1 leaf module to
power the auxiliary system.

11 leaf modules charge to 4.1V so the pack voltage is 90V which is the
max voltage of the controller.
I am using a 12V boost module to increase the 12th leaf module from
~8V to 12V
System Voltage90 Volts
Charger Mean Well HRP-600-36
I am using 3 Mean Well power supply's wires in series to charge the
I am using 2 mean well HRP-600-24s and 1 HRP-600-24

The 24Vs are set to max 28.8V @ 648W
The 36V is set to 33.4V @ 630W
This should give me about 20A of charging
DC/DC Converter
I'm using a 600W Chinese boost module to boost from 8V to 12V
I'm looking for a higher quality if anyone has any suggestions, please
let me know at the link at the top
Top Speed80 MPH (128 KPH)
I reached 80 and was still accelerating, I backed off until I am more
comfortable on a motorcycle that I built myself. Lol
AccelerationI have a 15 tooth front sprocket and and 41 rear. Not ideal, but ok for
now. The acceleration is quite snappy, I got a 6s 0-60 once, but have
only seen 8 since then. I still have a lot of testing to do :)
RangeI have done 35 miles, but did not make note of the start and end
voltages, so I don't know what the range might be yet. I am hoping for
at least 60 miles.
