I have got caught up over the holiday doing stuff on the house, but I have been researching and drawing up the schematics for the motor controller on gEDA. The first draft of the schematic is about 80% complete and I have layed out the components, I just need to do some tweeking and adding in component details(resistor and cap specs etc). I hope to have to up within the week for comments/feedback.
I am now looking at getting 18 of the EVH15120. These are a comprimise between price and performance. Since they are designed for EV use they should last a while, they will fit into the frame of the bike, and there not too heavy. The upside is there easy to get and at least half the price of Lithium. The downside will be the weight and the charge time.
I have attached the LED blinkers to the bike and here is a pic.
And the back...
I have bought some workshop equipment that will help me with the fabrication of the batttery case/tray and motor mounting brackets etc. I have got most of the electronic components that I need to build the controller too.
