Hey Anthony,
Thanks for the kind words.
My car really has been a continuing project, and I am always experimenting with it.
The single setup that I have used the longest was a 72V system. That's only 6 12V batteries in series. 72 volts is one of the natural cut-off points for the cost of many parts. 72V chargers and controllers are not terribly expensive. I was driving the motor with a Curtis 72V 300 amp controller during that time.
The car had fairly good performance for around town and roads up to 45 mph speed limits.
Also, at 72V, upgrading the suspension really wasn't an issue, and I had plenty of trunk space. 5 batteries went under the back seat, and one was under the hood.
The 72V system wasn't great on hills, and range was limited to about 20 miles total (running on used batteries).
Overall, a 72V system is great for anyone getting into electric cars, without costing an arm and a leg. It does have its limitations, but is still great personal transport.
