KILLER KART, 19KW ETEK POWER, 50 AH BATTERIES, 50 MPH
Well here is again another start of one of my projects. Starting with a stock racing kart with a 100cc two stroke motor.
I removed the motor and related parts and sold them on ebay. I recovered the cost of the Kart from the sale. Here is what the kart looks like half way through the convertion.
Electrical control box and gauge. 400 amp Alltrax controller and contactor behind the seat.
Custom motor mount for the etek.
Started mounting the 50ah B+B Batteries. Four in total (48volts). Will add more info as I go along. Jurgen

Ah, nice to see an electric kart on the forums! Only ridden one once, but it was AWESOME.
Can't say the seat strikes my fancy. Needs to be black (mebbe blue...) to match. Love the carbon fiber, though (I think that's what it is).
How fast you trying to go
?
EDIT: Freakin' duh; right in the title.

Looking good! Never driven an e-cart but have driven a 100cc race kart exactly like that one - awesome fun!
I wonder if you could make a bunch of them and then open up an all electric race club. Back in the UK about a decade ago it was a popular event to go to an indoor kart track as a group and race the "Honda lawnmower engined" race karts (good for about 40mph? maybe?). Might still be popular. Electric karts would be better for an indoor racing experience than gas ones...
Anyone want to go in with me and buy one of those derelict Detroit buildings and open an electric kart racing club?
------------Re: KILLER KART, 19KW ETEK POWER, 50 AH BATTERIES, 50 MPH
Thank for all the responce. I am looking to get the kart going speeds of about 45mph to 50mph. I don't want the gearing too tall. I want to be able to power slide and do donuts in the kart. At 400amps I may only get about 30 min of real fun time, regulated down will be much more. I am starting all thie wiring today. Cheers
Re: KILLER KART, 19KW ETEK POWER, 50 AH BATTERIES, 50 MPH
That is way cool!
How come you get all the cool toys?
I can't wait to see a video of that thing. With the right gearing and weight distribution, you should be able to drit it nicely.
Re: KILLER KART, 19KW ETEK POWER, 50 AH BATTERIES, 50 MPH
This is fantastic!
I built an electric go kart a few years ago out of a sprint kart using the same gear; Etek & 48V Alltrax. But it was only done as a proof of concept for a larger project and wasn't as nicely done as this. Very well done! I only used 13Ahr Hawkers though so it would only have a run time of less than 5 minutes. When paced against my friend's pickup we figured it could hit 50 mph (difficult to verify since we would run out of room in the parking lot that we tested it in). We only got the truck to 45 mph until it had to break, but the kart had a little more acceleration left.
Do you have videos of this running?
Re: KILLER KART, 19KW ETEK POWER, 50 AH BATTERIES, 50 MPH
Here are a couple more pictures of the wiring. First test went good. Left some rubber on the road. Hope to get some video up after the finishing touches are done.

Re: KILLER KART, 19KW ETEK POWER, 50 AH BATTERIES, 50 MPH
that kart looks a lot of fun. Are you going to race against gas Karts?? how does the performance compare?
Re: KILLER KART, 19KW ETEK POWER, 50 AH BATTERIES, 50 MPH
Bravo! For such a job well done!
Might I add a simple "diagnostic" ?
After a good hard run, use the back of your
fingers ( thin skin) to touch all connectors,
heatsinks,wires, pretty much all power transmission
parts?
The temperatures will tell you a story....
Good job!

Re: KILLER KART, 19KW ETEK POWER, 50 AH BATTERIES, 50 MPH
Oh yes,
Your red "disconnect" button is well done also...
( easy to activate, simple, well done)

Re: KILLER KART, 19KW ETEK POWER, 50 AH BATTERIES, 50 MPH
Well it is DONE!!!!!!!!
Some minor adjustments of the controller, etc and............Nothing but rubber left on the road. This thing pulls, slides, spins, and takes off like no other kart. Here are some other pictures. I will be taking it to the local track to see how it does against the gassers. I already have my eye on another EV project so this kart may be sold to make room. Will probably sell it at the cost of the build. I added all the numbers and it came to a total of $3700 to build this kart not including labour. Let me know if you are interested before I sell it on ebay. I will Crate and prep the kart for shipping.
This kart was built on a used BRM rolling chassis, and all other parts are new.
Re: KILLER KART, 19KW ETEK POWER, 50 AH BATTERIES, 50 MPH
This is a very similar arrangement to a kart I developed last year. Same motor and controller package, and I geared it for about 50 mph as well.
I sure could use better batteries though. Just Autocrossed it yesterday and would love to be able to get the batteries to last long enough at peak power.
