Electric conversion crawler build

[Evcrawler]

Pulled out the supercharged v6 with automatic and replaced it with a Warp

9 electric motor from Netgain and a t4 out of a cj

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.

Awesome. How much does the batteries weigh?

Thanks, 400 lbs. for the whole volt pack 360 volts 50 amp hour. That much lead acid would be 1000lbs.

Is it true these cells are built with 18650 batteries?

No, these are pouch style

edit: I'm an idiot

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

I have zero experience with these motors. What's that noise? Sounded like the engine engaged, some kind of whining?, and then mechanical transmission whirring.

 

[Beerj]

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.

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

 

[Blase]

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?
