Hello from Australia.
I am interested in building an electric powered motorcycle as a cheaper alternative to petrol power.
The problem is that batteries cost more than petrol.
Example.
Panasonic, NCR18650, 169 batteries
48v, 40a, 1938 watt hour.
13p, 13s, Weight 7.61kg (45g each)
Cost: 169 batteries x $7.76 each = $1,311.44 Source (http://www.banggood.com/NCR-3100mAH-18650-3_7-V-Lithium-Rechargeable-Battery-For-Panasonic-p-72905.html)
How much petrol can I buy with $1,311.44? 931 litres, which on my cbr125r takes me a staggering 32,576.58km at 37km/L.
Will the above mentioned battery pack last 32,576 km before it needs to be replaced?
Note: If there are batteries that sell for much less then let me know as I'd like to make this project work.
Also note: Sure I could build a super light and efficient motorcycle with minimal frontal area and aerodynamic fairing to extend the range but if petrol is still cheaper then electric is bunk.
