The rear battery boxes are nearing completion. There will be 12 cells in each box.
Tremelune, thanks for your post. Originally, I was going to convert a truck, because lead batteries need a sturdy platform to handle 2000 pounds of lead. So these batteries are the hot new batteries I needed for my project!! Once I decided to use lithium and switch to a sports car, I felt it would be a crime to end up with golf cart performance.
But you are correct, if electric cars are to gain market share, battery technology must continue to improve. I think that target goals are 300 miles range, 10 minutes to refuel, and $5,000 price tag.
