Two things I would suggest. Don't have those black and red wires crossed where they bolt down behind the seat. That's a short trying to find a place to happen. Vibration could cause one of the wires to wear through at some point. The other would be to program the controller to limit the speed in reverse to something like 20-25% or so. You don't want to suddenly go careening full speed in reverse if you suddenly hit the throttle pedal to hard. You may have already done that, or its already programmed in and you just didn't say in the video. Cool build either way. That thing is going to be a ripper as long as it doesn't kill chains all the time.
Def need a swaging tool. Using the vice will create a high resistance joint, if not straight away it will happen after a time. A swaging tool is designed so it wont loosen over time. If you need to solder will work but corrosion and vibration will be an issue after a while Also get a ratchet crimper for the smaller connectors. Using the tool you have WILL create faults after a while. Tech 34 years. Learnt the hard way!
This Electric-Kart was on my list, I'm kinda glad you beat me to it though so I don't have to build it now!, Awesome project I can't wait to see this thing light up the tires!.
Sweet glad to see someone doing the same as me. Im building an all wheel drive kart. I built my battery back out of 21700 high amp batterys. Im building my own hub motors right now and hydraulic brakes. The motors should be able to push 8000 watts each. I need to get my vesc motor controllers but slowly working on it. I wish there was a forum out there. Who knows i might put one up
This is a pretty neat project... Might I recommend for if you do a future one though you might wanna go brushless and try a Sabvaton motor controller similar to the ones used on electric bikes... they have an insane amount of configurability and even a mobile app which can be used in conjunction with an optional bluetooth module to be able to eyeball every aspect of the controller's operation as you're running it.
YES! We have this on our build list too. We have 2 kart builds at the moment in the garage... the wife is going to kill me soon I'm sure! Check out the builds we've done!😀
Very nicely done! About that resistor, in the RC field/e-skate we call it anti-spark, it reduces the inrush-current preventing your connectors/terminals from being eaten away.
While that is all good and I applaud your effort. There is no need for all that work. I built trike out of 2x4s and deck screws no metal except the screws and some bolts for motor mount. 3000 watt motor running off 2 two 40 volt 7.5 ah batteries in series and it tops out at 39 mph. Really easy build took about two weekends to build
You may want to push more than 350 amps with that setup. Drive sprocket may be to big. Your setup can handle 100 additional amps for some real fun enjoy and keep doing what your doing!
Hey if you guys want to re-do those lugs I have a nice Greenlee hydraulic crimper with dies. Watching your videos I think you guys live just a few miles away.
Harbor Freight has those wire crimpers they're not expensive hydraulic ones are the best ones that get though and I think they have them too for pretty cheap drop a solder for good measure even might help but I'm not telling you guys anything you don't know but loving the electric cart episodes
For once UA-cam puts a video in my suggested list that is highly interesting to me! I’ve built a couple of shifter karts in my days but none that were electric..this is a sick build! Subscribed!
All those diagnostic tools are so expensive.. if engine manufactures would just use some standards (I have seen some Cat5 connections on engines though, good job!), anyone with a computer could diagnose anything. But what an awesome build!
Cool Man !! I've done something similar for my final graduation project at the university although I had 2 motors, 1 for each whell and therefore being eletronically controlled individually .. The project was an eletronic differential .. worked quite Nice at the last minute 😂😂😂 all hardware and programming was handmade só cool stuff
Fyi, try to allways put your part in the center of the vise when forcing hard on it. Also use anti seezeon the threads of vise for more torque with less pressure needed.
Next time, put connector in vice heat fill with solder. Cut your wire, heat your connector again to melt solder and stick in. That's not a great connection by crimping in vice. Great build guys!! Love it
Should've run with the 2cycle on it so they could have something to compare it against. All those batteries with their weight plus all the structural welding is going to hurt the handling a lot.
Dang Bro I hope there dry cell battery. Nothing like going out in fire ball of sparks and acid burns ....lookin forward to your test drive good luck ..I'm only kidding looks mint ....UK England
I love electric builds! My golf cart does the same thing,when I turn the key on,the motor turns a little bit.......I never did figure it out,probable speed control issues
besides the contactor do you have any other way to isolate the battery like a manual emergency disconnect switch in case the contactor welds itself shut?
You literally took everything that makes a forklift run and put it in a cart 😂 a lot of these engines “brake” is called plugging which is basically giving the motor throttle to turn the opposite way it is traveling therefore braking the machine. Also you should be able to set and adjust the coast speed/distance. Awesome build can’t wait to see it burn the tires off 😎
@@juantabby4787 yeah well excuse me for my wifes nick name being on my post but I assure you I have awesome go-karts you might have seen them on the tube

Guys get a hydraulic crimper for those large cables. Amazon has them cheap. Its worth the investment.
Or aslease solder them...

@@lennym1273 soldering isn't adviced in vehicles. Duo to vibrations. The wire then easily breaks right next the solder.
What kind of electric motor you use?
Awesome guys!

Can you help me make when I have a frame already
And again ur evrywhere

Guys this build is so awesome great work fellas thing bad boy is so clean
I was literally designing one of these the past few days and this came up in my feed. This will help a lot!

That is going to a blast to ride
Who just wanted to see this thing rip???
This whole project is way above my pay grade. LOL Great work guys!
Fantastic work. It's going to accelerate so hard I bet.
Great job guys! (Maybe time to replace that bent drill bit. Haha!)
Great video You have a great future in the electorate automobile
Hey if you guys want to re-do those lugs I have a nice Greenlee hydraulic crimper with dies. Watching your videos I think you guys live just a few miles away.
I'm wanting to do a electric build. Maybe a kit car but this looks really fun
Very cool build guys!!! Looking forward to seeing the rubber hit the pavement!
it took 7 seconds for me to subscribe..
*my curiosity has been raised*
U guys are killing it , cant wait for the completion 👌🏾👍🏾

*I like how you guys don't have an obscene mouth. 😊
Thats actually one of the coolest thing ive seen in a long time mate 👍
Well done, good work
Respect
Didn't even watched 20s of the video I already subscribed 🤟
You know your shit nice work man clean build
Very cool

Excellent work, great video.
Hey umm that C10, i love it.
i dunno if id trust those rivets on that chain guard. a high speed impact would probbably rip those out

Dc brushed motor 😍
seems nuts.
What motor/controller is this ?
Next time, put connector in vice heat fill with solder. Cut your wire, heat your connector again to melt solder and stick in. That's not a great connection by crimping in vice. Great build guys!! Love it
Love the build
Nothing like instant torque from an electric motor......
Bad azz!!! I just SUBSCRIBED!!!
Thank for the video
that thing is going to rip! lol
Do you have engine braking enabled? That's always a cool option on eletric motors.
Good build, keep it up.
I would have assumed that to be part of the regeneraive function.
Looks like a very neat Go Kart, Good job. Do you have links were to by, specs on the motor? Thanks
Hope you soldered the lugs ..... only way to get a overall good connection inside of lug
I wanna see an inverter-run 3 phase induction motor go kart
Good to see you posting again.
You should take the kart to track and get a lap time
Should've run with the 2cycle on it so they could have something to compare it against. All those batteries with their weight plus all the structural welding is going to hurt the handling a lot.
True
We actually have a video of this exact kart with the 2 stroke at the track. But yeah good idea we should totally compare before and after lap times!
Dang Bro I hope there dry cell battery. Nothing like going out in fire ball of sparks and acid burns ....lookin forward to your test drive good luck ..I'm only kidding looks mint ....UK England
Awesome build! Could I get the motor and controller models? I'm trying to do a conversion of my own!
Good luck with that chain guard tho
I’m guessing those wires need to be larger size. A lot of amps going through them.
Epic
I love electric builds! My golf cart does the same thing,when I turn the key on,the motor turns a little bit.......I never did figure it out,probable speed control issues
besides the contactor do you have any other way to isolate the battery like a manual emergency disconnect switch in case the contactor welds itself shut?
If you have the budget, get the drive system from an Alta dirt bike.
Would be interesting to know what motor, controller and batteries you are using if you could add them in the parts list in the description.
Wondering how cheap it is and if the controller will work for a larger motor I’m betting
Can you post part numbers and the notes left by the students? I’m looking to build something similar this summer and wanted a little head start.
Great build but please get yourself a heat gun for the shrink tubing.
Holy cow how many batteries?!
Nice build! I was wondering who you rented the programmer from?
Gearing that motor up high like that might be sluggish and draw alot of amps
A wreck is going to awesome! I can feel the battery acid eating my flesh as I write this...
a wreck is going to awesome i can feel the fire burning my flesh as i write this..
hope you have a kill switch that easy to get to
I have a feeling that the motor is going to snap that chain.
EnlightenedSavage if he tuned it to not snap the throttle
A bit on the heavy side for racing right?
have any recomendations for a bms?

No it's when you short the motor out and it stops.
Surprised to see you used crimp on instead of soldered on rings on those high current lines.
How much energy is wasted because of the precharge resistor?
Hey guys this is Jimmy let me know when you get one to race mine with
But your name is Lisa!
@@juantabby4787 yeah well excuse me for my wifes nick name being on my post but I assure you I have awesome go-karts you might have seen them on the tube
Lisa Callie just givin you some shit, I find it funny.
Looks like the flux capacitor
bro... can u share brand and model of that motor and the controller?
yea the only draw back to DC if it bites you it will not let go like AC
I love it but whare is the rotery
How much does it cost to do it? because I was thinking about do it to my vintage go-kart
Dude where is that behemoth of a motor from?!
Porque el asiento en estos chasis está un poco hacia un costado?
Dont punk out full speed runs turn it up max
👏👏👏👍👌🇳🇴
Porque tiene 3 rodamientos en el eje trasero?
I can’t find Part 4. I hope no one got hurt!
what is the wattage on the motor? i am building an electric system and i am looking for a 6000 watt+
I don’t see that rear sprocket lasting very long
How much did it cost you to get this far?
bro what is the cost of motor including controller plz plz reply
How big is that battery
whats the battery config
what's your gear ratio
WORST CRIMPING EVER! Using a vice omg lol
Oi
What’s it weigh?
When’s the next video on the rotary kart? Or is there ever gonna be another video on the rotary kart?
Ya’ll should really put the rotary on a bike or get back to riding the kart
Go zoom
I would find charging and the small range annoying on this kart
