Burned up my Altrax 4834 after 500 miles due to no heat sink and hot rodding and most likely not letting pre-charge resistor do it's job when starting it up.

Sealed Lead Acid, 38amp Hour
System Voltage48 Volts
ChargerZivan NG-1
Zivan NG-1 for charging at home. 2 Hours to 85% recharge, 8 hours for 100% charge. See data at WebPage Have cheaper, lighter, smaller charger mounted on bike rated at 4.5 amp. for emergency recharges during ride, and for topping off at work.
DC/DC ConverterSevcon 300 w
InstrumentationPoor-Mans-Pack-Tracker: A Six position rotary switch switches a single, Auto-ranging Volt meter between 50mv/500amp shunt, pack voltage and each individual battery voltages.

Kill-A-Watt P3 meter used to measure actual power drawn from 120V outlet when recharging.

Watt Hours/Mile53 Wh/Mile
WITH DUSTBIN + RED FAIRING On Top: 53 Whr/Mile

("Kill a Watt" recharging measurements .72 kwh / 13.7 miles = 53 Wh-r/mile).

It is pulling 15-16 amps on flat and steady at 28mph with Dustbin + Red Fairing on top in fully tucked riding position.


WITH DUSTBIN ONLY: 58 Whr/Mile
("Kill a Watt" recharging measurements .5 kwh / 8.5 miles = 58 Whr/mile)


RED FAIRING ONLY: 72Whr/Mile
("Kill a Watt" recharging measurements 1.81 kwh / 25 miles = 72 Whr/mile).

Conversion Time?? Began February 2007 and it never ends. It's a lot of fun experimenting and riding.
Conversion Cost$2,400 Electrics (Motor/Controller/Batteries/DC-DC Converter, Charger etc.) plus $550 to purchase and rebuild motorcycle frame (bearings, tires, seals, aluminum, hardware, brake pads, fairing, etc.).

Plus for Airtech Fairing (approx. $800 delivered)
Additional FeaturesAdjustable Throttle Response (0-10K Potentiometer in parallel with twist grip) to limit throttle response (for controlling max speed and for loading into my van, and works great with throttle lock to give fine control over cruising speed).

Mechanical Throttle Lock.


November 2009 Update: Updated Mileage - I've rode 800 miles since installing the dustbin fairing this year.

My batteries have been weak all this Summer due to my running them to 80-100% Depth of Discharge for the previous 2 years. This really cut into my miles as I was limited to riding 14 miles each way. Plan to purchase some new batteries for the 2010 season - hopefully something better than Lead...

August 2009 Update:
- Added recent picture with new vintage tail piece
