I built an electric Hillman Imp 3 yrs ago. 680 kg ringing wet.
4 wheel disc brakes, kombi gearbox, go-kart handbrake etc
But 144v of nickel zinc batteries for my car = $5,500 from China.
So I put the whole car on hold. I'll get back to it later when batteries
come down in price. I don't want to use 12 trogen's bats @ 372kg.
