The heart of the conversion of electric car is the battery. Without the batteries your car or truck will go anywhere.
It is important to find the right type of batteries though. You need some kind of battery called deep cycle battery. This means that the battery is designed to be nearly depleted and will continue to be a fee if you take reload. If you do not get this type of battery and after the first two charges to your electric car batteries no longer work. Also, make sure 12 volt deep cycle batteries.
There are several sources where you can find these batteries for free. One of them is your local golf course. I used to work at a golf course when I was a teenager, and every year or two we change the batteries, replace the golf carts and she was replaced by new ones. The batteries are still good, they were replaced only for routine maintenance. When I convert my electric car I toured the local golf courses and managed to win 20 or 12 volt battery to discharge. You still have years of life left in them, and if one breaks I have a couple of replacement.
Another source of batteries without forklift. These are to be replaced usually every five years or more. to find if you ask around the District for the storage of your city, you should be able, a few of them. These batteries are great and they are designed to last at least 20 years.
The problem with the forklift batteries is that they are slightly larger than the conventional 12-volt batteries to not be able to adapt, as much in. .. or you can not adjust to the situation at all. Shall use forklift batteries, use a car must be large enough, or you can go to clear your trunk and there.
There you are, what kind of batteries you need to convert your electric car. I recommend that you measure the dimensions of the inside of the hood and trunk, so you in a position to forklift batteries are used or if you know regular batteries for golf carts. Both are very good, but the forklift batteries can store more energy.
