10 Build Your Own Electric Car: Batteries
In this video, we consider the batteries we will use in the car and how to connect them. Please note that this video is only covering lead-acid batteries, as it was filmed and from a project a number of years back. Principles of safety, serial vs. parallel connections, etc, are still useful knowledge. Most modern conversions will use lithium batteries, and batteries from salvaged commercially-built cars are often the best value.
For a project using salvaged Nissan Leaf electric car batteries, please take a look at my Vectrix playlist.

This video is one segment of an instructional video I created in 2010 from a home-built electric car I made in 2008. Of course, battery and motor technology has advanced quickly since then, and affordable, commercially-built, Electric Vehicles are now a reality.
This video series covers ONE low-tech and simple way of converting a car to electric. Many of these same ideas and techniques still apply to go-karts, motorcycles, boats, and lots of other projects. We hope that you enjoy watching these videos and learn a little something from them.
A simple electric car conversion project like this one uses
A 0-5k ohm potentiometer throttle: https://amzn.to/2PwMmoD
A motor controller up to 144V: https://amzn.to/394QyUh
A DC Series-Wound motor (9-inch diameter typical): https://amzn.to/2TlqYUv
Battery Charger to match your pack voltage: https://amzn.to/2Toe0Fl
On this car, we used a simple power inlet: https://amzn.to/3abNWnI
But that also meant we needed to design a separate circuit to disable the ability to drive while plugged-in. That's a built in feature of the now standard J1772 connection used in modern commercially-built cars.
J1772 Inlet: https://www.aliexpress.com/item/40000...
You would then pair that with a standard J1772 EVSE: https://amzn.to/387ixRW
I show the internal connections you need for the J1772 communications at: https://300mpg.org/2015/03/31/the-diy...
For a good book that's an introduction to modern lithium battery design, please see Micah Toll's DIY LITHIUM BATTERIES: https://amzn.to/2uEP30g
There are still a few copies of the original DVD for sale. Besides the video, the set also has a DVD-ROM with photos, web clips, and documents from the project.
All profits support our work and go towards future DIY Clean Transportation and Renewable Energy Projects.
