Research for a 1:1 electric car - RC-Monster Forums

Hey Sike, I am only a few weeks in on the research... As far as the mech connection go I should have all of that covered. Wiring will take time, but the worst part will be the battery placement.

I will definately pick your brain on the forklift motor. I have some info that a 90v or so setup should meet my goals. Looking for 30 miles range, and 45mph max speed. Just looking for a town car, not going on the interstate. 15 6v lead acid batts should do for what I want.

Sounds like I can use a forklift motor for propulsion, stick with a manual tranny and clutch for easy operation. Probably stick with a curtis controller as they seem to be the best priced. Will make my own adapter plate, and maybe have a coupler made, or buy one if they are available.

James, look at the 914 electric conversion. It's a decent set up and will be more then enough for your needs.

The "town car" goal will be much easier to achieve. Why use 15, 6V batteries though? Why not just 8, 12V batteries? It would make your wiring much less complicated.

Funny. I will use the 6v batts as they will offer more watt/hrs, so more range.

Ok, will do!

Wouldn't gell cells give you the same bang for your buck at a lower power to weight ratio? Gell cell prices have come down a little in the last two years, and I am willing to bet that you can find a fair deal through one of the battery wholesalers.

Do you mean AGM batts? I use one in my motor cycle. Not much better than lead acid for bang for the buck... I was going to use lifepo, but they are still a bit new and expensive.

Yea but considering what you are trying to accomplish wont the gell cells be a better choice over lead acid for the weight difference in keeping your load down? Just curious.. Sorry don't know about the Lifpo line either.

I have priced some gell cells and they seem a bit much... Looks like 12 6v batts will do what I need, and not cost much over 700 bucks...
