Excellent! Thanks for the advice, I am doing some research right now on batteries and run time, I did a 10hp motor which ends up being 7.5kw at 48v which is 156amps. Tell me if I'm doing this wrong as I'm rusty on my power math but that would mean if I had a battery setup (48v) rated at 156amp-hours I would get 1 hours worth of life out of my motor before running out of juice?

Another question can solar panels be placed in series? 12->12->12->12 = 48v or does that cause problems with solar? if placing them in series would work 8-14watt panels would put two 4 panels sets in parallel creating a 9.333 amp charger and if it's 9.3333 amps it would be putting 9.333amp-hours back into the batteries after 8hours you would be approximately 50% charge. That's all pending my googling and what little I remember from college holds true.

That being said if any of the above is true it would be a miracle but I believe you could get enough solar on the car to increase the range by 50% of just pure batteries.

With the addition of a lightweight small ICE you would have a vehicle that was limitless if you stopped to let it charge :-).

Also, I was guessing a 10hp motor would be sufficient for in-town speeds 40mph or so, what specs would be used to size a motor, say the weight of the vehicle was 2000lbs (907kgs) how would a 8hp, 10hp, etc move that amount of weight? (I'm a little more electrical then mechanical).
