@@SKITYSTUDIOSQs motors. Ko F spec motor. Keep in mind thats peak power, and to reach that capasity you will need to put down atleast 5k on motor, controller and battery. Just go with a qs138 3000w motor, those peak up to like 7-8kw. And sends a gokart 0-100kmph in under 3 sec. Cost me around 1500 $ for all electronics(aswell as buttons, cables, cable management and some volt indicators and other small things you never calculate for but ends up being hella expensive😅
I'm doing a build with the 72v 3000w motor. There have been complaints of the motor overheating and then dying. My guess is the lithium batteries that people use is making them faster, but the high discharge is causing the motor to overheat. Some people are enlarging the holes on both ends of the motor. This works well if it has a built-in fan, but from what I've seen the 3000w motor doesn't have a fan ( strange I know). I'm planning on using a 100mm 12v Seaflo in line boat fan with a electric bike 72v to 12v step down transformer (perhaps with 4" k&n filter on the end to keep dust out).
To me the 3000w motor is the same as the 1800 w motor. It’s almost as if they just took the same motor and hooked it up to a larger controller. I am looking into QS 138 as I think it’s a better fit for most of my project ideas
@@CJs_DIY Interesting. In UA-cam videos I've seen lower wattage motors have a fan inside the case, but I don't know if that's all of them. Apparently there's no room for a fan with the 3000w version because the case size stays the same with all models. I'd like a QS motor but the price is a bit high for me. Even the recommended controllers for a QS motor costs quite a bit :(
Motor is 1800watt rated but can output more if more amps in as well voltage up ....all is pretty much dependent on motor controller voltage and amps ...so more volts more amps. E motor outputs more power measured in watts ...but limit is actually cooling of motor winding.
Lithium battery pack is a better choice . We are using 3.5kwh or 66a Nissan leaf lithium battery and never ever ran out if juice. With a ultra high performance 15a fast charger that can fully recharge the battery in 2-3 hrs. The only negative about it is the high cost, $800 . But well worth it.
I'm curious how you connected your charger. Are you using the charging connector on the motor controller or did you make a connecter going right to to the batteries?
what's the power like for an adult? I have a gas powered 150cc buggy and thinking of doing an electric conversion but not sure whether to go 1800w or 3000w thanks
You need to put a charger for your specific battery type. Lead acid or lithium and then choose the charger for that voltage. I used a lead acid 72 volt charger
Hi I'm currently building a electric drift go kart with PVC sleeve tires not sure if the 1800w motor will have enough power and should I just fit a 3000w motor instead so I have enough power for me to drift properly
@@axelsol89 the 3000 w motor kit comes with the exact same motor so I left the original 1800 motor on the kart. And yes you will drift like a machine with pvc/plastic tires
@@CJs_DIY I didn't know that they where the same motor I thought the 3000w being bigger, has a different rating/power sticker and higher price meant you where getting a bigger motor I'll have to look into it that's good to know mate cheers
Thank you so much you have answered my questions for the speed controller
No problem
Nice! I'm also more or less in the middle of an electric go kart conversion, mine has a peak power of 20kW 😂
Where do u get the 20kw motors ive been lookig for ages

FYI the 3000 watt motor has a marginally (1/2 inch) longer stator which should give it slightly more power.
Thx I’ll switch it over
Will it eventually kill the motor if i use the 1800w one with 3000w controler

I have been eyeing some lithium pacs that are plug and play... def worth it but pricy$$$
That is awesome Colin!
Thx
Mabe put a better chain guard on the chain as if it snaps it can take your arm off.
Not a bad idea
I'm curious how you connected your charger. Are you using the charging connector on the motor controller or did you make a connecter going right to to the batteries?
Charging connector on the controller
If I remember correctly I tested the wires to determine pos neg on both the charger and the controller then connected them
holy crap he actually did it! well done *dudes
Nice Video!
How much Ah does the battery's have?
Not to sure but not a lot
what's the power like for an adult? I have a gas powered 150cc buggy and thinking of doing an electric conversion but not sure whether to go 1800w or 3000w
thanks
Go with the 3000
Thanks!
Would you say they have decent power? I picked up a 2000w one for a garden tractor electric conversion idea.
Might be a little underpowered for a garden tractor but yah decent
Nice
Is this a 72v setup now rather than 48v
Yep
does this come with a battery?
No
Cool subbed!!!!!
Can you list the battery charger for me please, I can't find it online
You need to put a charger for your specific battery type. Lead acid or lithium and then choose the charger for that voltage. I used a lead acid 72 volt charger
@@CJs_DIY I will be using 48V lithium ion
@@Lou246 then you cant use the same charger as I have in this video as it is for lead acid.
Are you selling that 1800watt controller? I just bought a 2500w motor and need a controller.
No but they are online for cheap

It’s the same motor the controller is all that’s different... I would go with the 3000 myself though
@@CJs_DIY so that's a 1800w motor with a 3000w controller with the actual motor it would have plenty of torque for drifting

How are those motors holding up?
I haven’t had any issues with any of these motors other then I don’t like the sprocket set up for them.
