Electric Car Conversion Questions (and Answers!)

Some folks have been writing in lately asking very good electric car conversion questions, and I thought, "You know, if I was thinking of converting a car to electric, I might find the questions and answers very useful..."

...so I decided to devote a page just to that; )

Here's where you can ask your question (pertaining to electric car conversions), no matter how simple, and I'll either answer it myself, or - if you've stumped me - we'll get one of my very smart conversion shop friends to answer the question.


Motor Questions
What size motor should you choose for your conversion? AC or DC?

Battery Questions
Which batteries are the best, and where do you find them? How do you wire batteries in series? Can I use airplane batteries?

Battery Charger Questions
Why do I need a special charger?

General Conversion Questions
Should I convert my monster truck to electric? Where do I get fuses? What's "electric reverse"?



Has your question already been answered? Try searching the site!

Don't be shy!

Do you have a conversion question, but don't even have the mechanical skills to know how to ask it, or whether the answer was already in the book you bought but you didn't understand it??

No need to be bashful, we're all learning together here; ) Like my math teacher once said: The only dumb question is the one you're too shy to ask.
