Hi!
I am Ben Rypstra, I don't have much experience designing and building my own things, but I work at Perth Airport as an aircraft maintenance engineer, avionics, and I have a few years experience with maintaining and troubleshooting electrical systems and all that stuff.
I'm in the process of gathering info for my own EV conversion. I'm still tossing up between a motorbike or a small car (mini or mightyboy are my current thoughts), and I'm also pondering battery type. And, well, everything else. heh.
