The heart of any electric car conversion is the batteries. You will need special batteries, called deep cycle batteries in order to make your electric car work properly.
These batteries allow you to charge quickly and discharge further than regular car batteries normally found in your vehicle now.

They are called deep cycle because normal batteries would be wrecked by the frequent draining of the batteries used in the system. Think of it as pouring water out of a glass. A regular battery you can only pour about 10% of the water out, but a deep cycle battery you can regularly discharge down 30% or so.
You don't want to go lower than 30% down though. Topping up a battery that is to the 70% level is as low as you go.
Where do you find deep cycle batteries? We have been living off the grid for over 10 years now and have been living with battery systems to run our home for that long.
The same batteries used with solar panels and wind generators are easily fitted to electric car conversions. They are easy to find, but can get expensive if you don't know where to look. The plans show some great sources of free batteries too. That is a great savings since the batteries for an electric car can be one of the greatest expenses.
A bunch of high school students can do it, so can you.
The good news is because building or converting vehicles to electric, the parts including the batteries are becoming easily accessable for everyone.
