Running low on fuel? Go Electric! Here's how I built my Mercedes Sprinter EV conversion battery pack. 360 volt, 23 kWh and a whole lot of wires! Can you build your own electric vehicle, well, with great care, a lot of patience and the right tools and equipment, I did just that. And then I set a Guinness World Record in it. The fact that it can make ice cream, well, that's just a bonus!
