Interesting. I figured they'd start showing up sooner or later. How big is the battery gonna be? Any plans for regenerative braking?

I’ve been thinking about it for a few years and finally found a deal on a kit that was missing some parts. Dc motor so no regen. Batteries are out of a Chevy Volt. Front pack is 168 volts 50 amp hour and going to put a matching pack in the back.BF0282C1-9B2A-4FC0-B476-B3FC8E4C82E7.jpeg

edit: I’m an idiot

Is the trans really necessary?
What part of the world you from?
Have you had a buggy before?

Do these type of electric motors have a minimum useful speed, like a stall? Just curious if a deep geared tcase is necessary or can the motor just go really slow.

Yes unless it is a Tesla motor that can do 18,000 rpm.

This is my 4th all tube buggy. Had a 5.0 on propane, 22r rear engine, 3rz turbo, supercharged v6.

I have zero experience with these motors. What’s that noise? Sounded like the engine engaged, some kind of whining?, and then mechanical transmission
Yeah it has a loud contractor that closes when I hit the go pedal. The whining is from the Curtis 1231 controller, the black box over the bellhousing. The v6 I had was really loud so it is going to be totally different being able to hear gear and suspension noise.

The way I understand it they have 100% of their torque at 0 rpm and require less gearing than gas motors.

very interested to see how this plays out!

Some really cool tech here and I think these will start to show up more and more over time

very cool!!! I have a lot of questions. LOL

What advantages are you hoping to gain over a traditional internal combustion engine?

What do you expect the battery life to be? Will you be able to wheel a whole day?

What is required to charge it? 110V? 220V?

Is the trans now like a reduction box or will you have a clutch and shift while moving like normal?
