70h and 90h is the size of the magnets in the different versions of the qs138 not the hp! If its their 25kw kit its only around 33hp.
was just about to comment this
100hp would be close to 75 kW. You would need a 72v battery that could put out over 1000 amps to power the motor.
Yes 25,000 watts ÷ 750 watts = 33.333333hp
750 watts = 1hp
if u look close at 5.11 min u see the motor is only 4000w
@@Danny-pp8xz that’s 5.3hp then
Just for your info, that's not a shifter kart. It's a standard 2-stroke kart. Shifters have a whole lot more kit to them, a shifter for one. Clutch handle, three brakes instead of one (one on each front wheel and a third on the rear axle). For the power and weight you have in there a three-brake setup wouldn't be a terrible idea.
Love this build, I have 2 karts I need to convert and your layout was clean, great job, I definitely want to see more electric kart content ⚡️
You should take this build to a go kart track and show it off to the people there and see how fast it is on a track!!! This thing is sick clean build man!
the controller has three wires going to the motor ...reverse two of the wires to change rotation
Yes it's a 3 phase brushless motor, but it's "sensored" so you cannot just swap the phase wires. It will smoke the hall sensors and fry the motor.. You have to go into the UI or app and change the settings to reverse the motor direction.
@tgif9735 not sure on these but alot of ebikes u can swap 2 on the motor and one of the same colors and one opposite color from what u swapped on the motor fir the hall sensor and itll work too
@Todd_Gerhardt those are Sensorless Brushless motors, Sensorless Brushless motors don't have the hall effect sensors and the circuit for the sensors used for finding the position of the rotor, so reversing the 2 out of the 3 phase wires has no consequences besides reversing the phase direction for power input. Sensored Brushless motors such as this one use hall sensors to determine the position of the rotor so it can start up and run smoother at lower rpms and be more precise with power delivery eliminating the cogging effect Sensorless Brushless motors have when at lower rpms or when trying to move from a standstill. but because of the sensors, you can't swap the wires to change the direction without de-syncing the sensor circuit from the phase wires and shorting it out making the motor and esc useless. So hence why sensored Brushless motors and esc's can't just be reversed by swapping phase wires like Sensorless systems, it confuses and shorts out the sensor system, each hall effect sensor has its assigned designated phase wire.
@@tgif9735 Oof.
@@Todd_Gerhardt If you do that with a sensored system you end up flipping the timing. Always do it in the UI. It takes but 10 seconds.
Amazing vid as always! Cant wait to see the full video of the go-kart :) And maybe some cool street riding too🤷♂
Thats freaking cool so much power i cant wait to see its full potential
I was thinking of building one just today, and then this pops up after I refreshed! Seems like a sign 👀
This looks fun but theres no way it makes 100hp, 100hp is 74kw and rough math that 72v battery would have to put out more than 1000amps to the controller with no loss to get 100hp, my guess is it probably makes 20hp but its torquey! Would love to see it on a dyno
I can tell from the speed it's making about 40hp If not even more
@@caluzzucarrazzi5549probabaly more like 20hp to 30
@@caluzzucarrazzi5549 dont' compare to gas, gas engines only have their rated max hp in a very narrow band of rpm, where as electric motors are much different. it might be a 40hp engine, but it might output 20hp when it runs
@@mattbanks3517 ?
@@mattbanks3517 yes
I built almost the exact same thing about 6 months ago. 2 72v EMBX batteries, a qs 138 90h motor and a 430a controller. With fully charged batteries we are at about 82v discharging 430a nominally that also gives us bursts of about 60hp at 45kw. It is an absolute MONSTER.
What controller did you use?
@@jeffhhdro the siaecosys/fardriver nd72800
Build me one lol
Holy shit thats insane
What are the exact specs of the battery you used? And relatively how long does it last before the kart is dead?
Best ECart I’ve Seen So Far🌟
If that screen displays Amps, the max draw I saw was 200 Amps, which with 72 Volts is 14,4kw, which is about 19 HP, which is still insane, but the title is quite a bit misleading, great content though, keep it up!
was thinking the same. 100hp is 75kw
19hp 😂
Dude, that thing is so sick. Great video man!
nice build i like the way you adapted the motor to the original motor mount. the rear gear bolted right up to the carrier. how much to build excluding the chassis.
dude thats mental . Cool build man
Loved watching you build this bad ass cart ! It is fun to be rich ! 😊
ill miss the old 2 stroke petrol go karting leagues, but its videos like these that get me hyped for leagues to switch to karts like these
Finally different montage music this time🙏
Old guy seemed awesome. That’s my plan when I get too old to ride moto is get into shifter karts
Wow wicked cool build
Hell yea I’ve had many margay race karts. Living in margay town and let me say these electric conversions can kick the 💩 out of a petro engine 👍🏼
Would running a battery up front, either where fuel tank would sit, help with balance/flex/grip? Or shifting the battery position net to the side pods more towards the front?
Just seems like an awful lot of weight to position so far rearwards and laterally. That's gotta adversely affect how the frame behaves and grip/drive is made. Plus there's little mass up front to act as a fulcrum like point for the roll centre, to be in/near the centre....
I just saw your video today that you did several years ago and you took my advice of going electric on this project. A smaller sprocket on axle produces increased speed but less torque. I would mount motor on rubber spacers to reduce noise. Also shielding the motor will reduce noise for quieter ride. Again, I was right by going electric. Sorry you live in NY with 6-months of winter.
So sick, awesome video 🔥🔥🔥🔥🔥
Very nice techniques used here.
Bruh that music during the build could not have been worse😂😂💀
that thing is so cool, crazy you uploaded this, im curently building a Surron Powerplant on a minibike!!
love the build the thing rips , but that aint 100hp build , that battery (and calbles) cannot hanlde the curretnt at 72v to get 100hp. maybe motor can handle it but that battery aint pushing that amount of power.
I’d love to do a 72 volt atv build. Get an old yfz 450 roller or something. Would be fun
Few small things:
- You don't have a keyway on the sprocket to avoid spinning the sprocket on the axle. Google "kart axle keyway".
- Lube the chain before every drive or you are buying new sprockets. Also the bearings, ball joints, front hub bearings.
- Buy a chain guard, if the chain breaks it could hurt.
Nice build!
Sick man
That’s awesome, what did you use to convert the twist throttle to the peddle on the kart?
Great video man!
That shit is crazy bro. Watching from Newfoundland Canada. Can’t wait to see more of this beast.
I want to build one of these as a fun alternative to doing road courses in my actual cars. I see it as a new hobby, a challenge of my tinkering skills, and a new wormhole to go down for years to come. I only fear fire upon rapid discharge/use and charging the batteries. Is the first mod to my shop a better fire suppression system for the garage?
So sick!
So dope🔥🔥. Hope Kelly Motorsport track opens up next to Area! But you should take it to Genesee Valley Cart club in Avon.
That "90H" kit is nowhere near 90 hp, its 25kw max output according to their webpage, that's 33 horsepowers...?
Badass! Haha cool build and I've liked your channel for years. Crazy neighbors sometimes but hey keep doing you're thing, broski. Cheers from Tampa Bay 🌴🤙🏼
I have 3 years of experience building a 130V 750Ah sustainable battery and I'm still not done. I broke more than 100 cells and a few BMS. To get that kind of performance, you need a really heavy batterypack. I currently have almost 65 kg two battery packs and only 3.38 kw. can drive only 2 minutes.
greetings from Germany
Can only drive two minutes? You're telling me you can discharge 130v 750Ah batteries in just 2 minutes?!
QUESTION!!!
Which E&C kit did you use for this masterpiece?
This one of the most tasteful electric conversion. It would be nice if you left a cost list. Btw you can adjust the ride height quite easily to avoid flattening the chassis tubes :) Oh and what is the weight?
and a chain guard ....when you get some time
ratchet strap for the battery
Those @mouscase Intra Lock System looks great!
Awesome!!!!
Sick!!!
I would like to know which exact specs did you pick through electric and co like for example what motor ,controller, battery , throttle etc for a similar build and I would also like to know the gear ratio.
SURRON KART YOOOOO THAT IS GENEOUS!!!!!!!!
My toxic trait is me thinking that I should build one of these.
AMAZING!!!!
Which kit on electro and do as when you press on link in description it just takes you to a page with multiple kits just curious because I want to build myself one
The music was fire af 🔥
Motor is a 4kW motor from QS motors (motor model visible at 5:27). I have some reservations about that "100HP" power figure even with larger peak powers in short bursts...
Looks like fun 😂
Nothing more fun than a go kart
About time. Something that's Shred tires. 👍👍👍👍
one question which qs138 motor is this? because i can see a lot of options what watts?
Sick bro 😮😯
Very nice respect
started watching like 5 years ago bro, first time ive been early enough to get a comment in, whip that shit
But how long does that battery last.
This is amazing. What time duration this battery? In extreme use, racing, what duration battery time?
I'd like to see an off road kart with full suspension
Look up cross karts
You earned yourself a subscriber. This was dope af!
Same this is the only vid ive watched from him and i just subbed
Alright, I figured it out. You have a misunderstanding of Electro's model numbers. they have a "70H" and a "90H" kit. This refers to the overall length of the motor, not its power output. The kit you have is a 90H kit with the EM-260 controller that produces a peak power of 25kW/33hp. not 100hp.
Not even that. Look closely about 5:12 in the video. The motor is a 72v 4000w ( 4kw, a little over 5hp).
@@jscruz2 You're totally right. I was mixing up the actual motor specs with the motor controller specs
@@jscruz2These motors are deliberately under rated by the manufacturer as a way to slip under the radar so to speak. Its clearly not processing anywhere near the claimed amount by the video. But, these motors are much more capable than their rating suggests. The qs138 70h can handle 30kw whereas the 90h version can do about 35kw at 72v before encountering heat problems.
There are no standard regulations for motor power at the moment, meaning its down to the manufacturers discretion. However in the last couple of years, certain ebike motor kit manufacturers have decided to take advantage of this and made ridiculous claims on the power level of their products. There's a mid drive cyc motor kit that the company claims can handle 5kw. It's a bullsh1t claim. The magnets are tiny and phase wires cannot handle the amount of current required to make 5kw even at 72v without heat damage.
Does the kit come with a pedal throttle?
Imagine if everyone commuted to work on these
Shifter karts usually have front brakes too. If the power is that high you might want to add those.
Tyler da 🐐
This is very neat. I'll be buying the kit for my e scooter and throw in a 32 tooth sprocket in the back and that will be neat. That not bad. Speed average 25mph on the speedometer reading ??
Bro said 100 mph 😂😂
I would highly recommend building a chain guard. That would be a bad day if that broke and whipped you
Hey, by the way in your description if I click on the link, it doesn’t take it to the page that I have to buy it so I don’t know which motor kit you got and I want it because I wanna make one
and of course donuts in the drive way is the first thing you do!!!! LOL
Wouldn't changing two of the three phases of the motor be enough to change the direction of rotation?
not on a sensored motor
how’d you connect the throttle and pedal?
Do a quad 🤘🏼👌🏼
All in cost on this?
You should check out this newer enging called the omega 1 it was based off of rotry engines a 35 lb engine making 160hp id love to fab one to a motorcycle.
I just need to know which sprocket and chain kits you got
How long can you run it before it overheats? With the controller in the tank it won't get any air flow.
How does that accelerator pedal work? Is it mechanical or electronic
Do you know of anyone that is a small kart/buggie that you can convert to electric that you can drive on the road? The kart that you did is super light but would not want to be on the road for if you got hit they would go over the top of you. Any thoughts?
Bro how did you fix that it spined backwards?
More like a 20HP go cart. The biggest motor that company sells is 14KW peak. sick tho
how much cost one like thish ???
Cant wait to see this race with an engine go cart
get a second battery in series and have it 144 volts go 100 this gearing
How much did this cost? Do you have a bill of materials you could share?
Welcome to the kart game 😎
You should take orders and start building them, since you know the problems you faced and now have it wired !
That one bad ass go-kart 👌 can't wait for the full video should race a tesla 😂😂
How long will it run on a single charge? Thinking of building one for Autocrossing. Wondering if I can use a single charge to be competitive or will I need more than one battery.
If you’re “racing” battery will go fast. This is why they switch batteries mid race in formula E
What is the stats on the motor and controller you are using?
maybe a few lead plates on the opposite side of the cart to even things out around turns? idk, center of gravity is so low it might not matter much.
9:49 all you have to do is swap any two wires on the motor. It will reverse the direction. Dont forget all this "new" E stuff is just RC car tech upscaled.
sick build man but I look through electron and co cant find the kit you were using
What is the battery leads and what is the controller that you are using?
How much is the build ?
where did you get the display?
