Vehicle1987 Honda H100-S2
Bought off eBay, not my ideal donor bike,
it was the one available, and I'm fairly
happy with how it's going so far.

Rated at 7kW according to the data plate,
actually down-rating it a bit!
MotorAgni Motors LEM??? Permanent Magnet DC
I'm fairly sure that the motor I have is of
Agni-origins, but the supplier apparently
gets them from some other manufacturer, so I
don't know for certain.

The motor itself matches the mechanical
dimensions of another Agni, though, so I
assume they're using the same plans. Pretty
happy with it either way.

Rated as 48v, 5kW.
DrivetrainDirect chain drive, ~3:1 ratio
ControllerAlltrax SPM-48400
Actually a lot larger than I had anticipated,
but the bike has a bit of room so I can cram
in somewhere. Still working out the final
Batteries32 Headway 40152s, 3.40 Volt, Lithium Iron Phosphate
8x 12v AGM cells, in 4 packs of two to bump up
the cell Ah rating from 22 (per cell) to 44
(per pack).
System Voltage38 Volts
Charger GWL/Power 48V LFP
Found a better charger overall, smaller and
handles a bunch of different battery
chemistry. Slightly modified to have sensible
automotive connectors.
DC/DC Converter Generic
48v-12v converter for 'normal' electrics
(lights,indicators,etc.) also feeding a 12v-5v
converter for ECU and other systems.
InstrumentationOriginal speedo/odometer combination gauge,
replaced tacho with an e-Xpert pro with a
prescaler for power output.
Top Speed90 MPH (144 KPH)
Untested so far, but free-air full-throttle
tests give a wheel speed of around 90mph...
which is terrifying, but encouraging.
EV Miles
Start:32,039 Miles (51,550 Kilometers)
Current:32,039 Miles (51,550 Kilometers)
Total:0 Miles (0 Kilometers)
Seating Capacity1 adult, (2 if someone is brave enough)
TiresStock (currently)
Conversion TimeToo damn long!
Conversion CostTo darned much!
Additional FeaturesShooting for J1772 compliance, so charger
includes AVC2 and J1772 type-2 compatable

Now have a refurbished BMW i3 slow charger and
a commercial 7kW unit on the house to test
this with, just waiting for enough of the
assembly before giving it a go.

The original bike had 6v lights too, so the
whole lot has been modernised to 12v, and will
be fed off the DC/DC converter.
