Vehicle1981 Yamaha RS 125 DX
MotorGolden Motors HPM-10KW fan cooled Brushless DC
Initially I struggled to get a certificate for
the continuous power measurements for the road
registration procedure. But the Swiss
registration officer assured me, that they
won't request this, as long as the declaration
on the motor looks trustworthy.
DrivetrainChain Drive
ControllerKelly KLS7250D, 24V-72V, 400A
Batteries72.00 Volt, Lithium-Polymer
New technology Graphene Lithium Ion Polymer
cells from Shenzhen WESTART Technology Co.
40 cells, 3.7V, 20Ah, continuous discharge
10C, totally 2.96kWh.
I'm building the battery pack myself. At the
moment I'm figuring out the best way how to
solder the cells together.
DC/DC Converter
I will change the board Voltage from 6V to 12V
Top SpeedTarget: 62 MPH (100 KPH) or more
RangeTarget: 31 Miles (50 Kilometers) or more
EV Miles
Start:20,533 Miles (33,037 Kilometers)
Current:20,533 Miles (33,037 Kilometers)
Total:0 Miles (0 Kilometers)
Seating Capacity2 adults
Curb Weight0
280 lbs (127 kg), estimated, including batteries
Conversion TimeI started the Project in November 2015.
I'm still working hard on the project. It's given me a lot of fun and
a lot to learn.
If anybody has experiences in building your own battery pack,
particularly in soldering battery cells with aluminum anodes: Any
advice is highly appreciated!
