It's funny you mention that. When I stumbled across the frame for it a week ago I decided to do just that. I doubt I still have my drawings and plans, and I'm sure I tossed the bicycle sprockets that I'd salvaged. But it'll be a good project to resurrect, and 25 years later I can improve a few things. And with no grandkids currently on the horizon I have some time LoL. I'll probably post the build on the Tube of You.
Seeing basically every new tool you have gotten/made recently get put to use was very fun and interesting. I have no doubt at the truth of the "I have learned a lot" statement at the end.
I have started taking the attitude that nothing is wasted if I learn something from it. And that’s helped me stay positive on little projects. So thanks for putting that energy out into the world.
Pro tip: when an internal fuse in an electronic device pops (ie one soldered on the PCB that's inaccessible without voiding warranty) there is ALWAYS a reason. Always. Maybe a transistor's gone bad, or a chip is fried. If it was a simple over current event, the manufacturer would have put externally available fuses, for example the glass fuses that some devices have in a screw type terminal.
You know your a quality creator when you can make someone who’s never interested in this type of stuff, sit down and enjoy a 30 minute video on engineering
I suspect at higher torques, the magnetic field from the widnings is strong enough to overpower the rotor's magnetic field. That in turn would cause the hall effect sensor to give bad readings. Try running more current through the rotor. Or make another rotor coupled to the alternator, with permanent magents, jsut to drive the hall effect sensor.
I think it's more of an issue of interference with the hall effect sensor itself. Either magnetic OR electrical. Electrical shielding of wires, and magnetic shielding for the sensor itself will probably be the key. Add a shield wire to the sensor wires, twist them tightly, and attach only one side of the shield wire to ground. Start with the small things first.
Always a master at making cool sponsored segments, you're the only person where I actually don't skip past them, I actually watch and enjoy them, and hearing you mention DankPods and Cashies gave me a good chuckle. Love from Australia 🇦🇺

As a German I had the time of my life watching this! The "Nein" was the highlight of your NordVPN ad, which was excellent as always. And the "wütende Elecktronen" is sadly misspelled, but also great!
I'm throwing a guess, but the hall sensor error upon increased current could be from electrical noise interfering with the sensitive hall signals, and then the motor controller freaks out.
I'd put money on it. Those little buggers are sensitive! Was having intermittent issues with one and the problem ended up being the trackpad on a laptop on the other side of the room.
Most likely an transient from the DC-DC coupling into the LV lines. Some shielded HV cables and better grounding might improve the behaviour but i would recomment a proper motor that already has the sensors as it might already have some filters or anything.

I know about adelaide. One should never go there, Its a hole. The "not the sunscreen song" told me 2 decades ago. Then again, New Zealand is a hole too so I feel a sense of camaraderie
This guy's video editing skills are on another level, i've never seen anything like this before done anywhere, nice job there, noticable effort in every part of his content
Oh, I remember randomly coming up upon the first video soon after you released it, and now, when I have completely forgot that this build exists, I randomly come upon part two :)
Hey man, gotta say, love your ingenuity and creativity, can relate to your headaches, failure attempts etc. I can relate to it because I go though these all the time. But every-time I manage to succeed, that's how I know you too will succeed. Looking forward to see the finished product working and your kid smiling.
Oof, hall sensor errors have plagued me with Kelly controllers. One thing I’ve noticed is my kelly is incredibly sensitive to hall signals that output a poor signal. Try scoping the hall signal and make sure your hall signals are clean and make a clean transition between high and low. I’ve had this issue in two motors, one was solved by modifying the motor and the other was solved with adding a little capacitance to the hall signal that has the issue. Let me know if you need any help! Edit: I should also mention that Kelly provided amazing product support. Send them an email and Fany will get you sorted.
Something doesn't make sense in his setup, he uses an alternator which afaik doesn't even have a built in hall sensors so unless he added them or uses a sensorless controller that wouldn't work
@@TheBlackAndWhiteCow He added hall sensors in his last video on this project. You would know this if you A) Heard him say he added hall sensors in his last video on this project, or B) Watched his last video on this project, during which he added hall sensors.
Gotcha, TH-cam failed to delete my comment for some reason because I posted it before I watched the whole part. still there's so much to fail when converting and you end up with subpar motor that wound up for low voltage and still brushed and you still have to match the correct voltage on the excitor coil, unless you do it for fun it's better to get a proper BLDC for that
This is a silly rube goldberg device that costed a fortune and doesn't work. Put a damn predator engine on it and be done with it. The kid absolutely will get over the noise. He'll come to love it and associate it with good times.
@@tarstarkusz Have... Have you been to this channel before? You think he works on stuff to get results? What a grand and intoxicating innocence. How can you be so naive? He does not own a Yugo or a Coda because they are sensible cars to own. He isn't converting a bus to a weird RV-car-carrier because that's a sensible thing to do.
It might be a longshot, but I'd love to see a collab with you and Mehdi at ELECTROBOOM to figure this out. Def need to walk away and spend some time on other projects, and I know this is sunken cost fallacy at this point, but it would be a shame to abandon this "Learning experience."
I tried (and succeeded, failed, repeated, and dismantled) a PFSense firewall project at home and it felt a lot like this one. Learned a fair bit about it, especially when I 'was in over my head'. Would not do again, but was nice to learn. Gave me troubleshooting experience.
There are plenty of people on here who will offer their advice etc. I just want to say thank you for posting two excellent videos, they were entertaining and informative, crucially they were also brutally honest - very few TH-camrs are honest and brave enough to show their failures. What I particularly liked was your approach to problem solving and analysis of the issues that arose. I think a lot of people seem to think that creating something like this is relatively easy - although you really did make it difficult for yourself by using an alternator! You've proved that's totally not the case! I look forward to seeing how you do in the next video. Thanks once again. Best Regards. Lin. UK.
I really appreciate that you also upload your "failures". I actually learn a lot from these videos. And don't consider them as failures, it's just part of the process!
@@GDMHificationranpitc I was just being a ball buster. I come for the entertainment, which he's successful at. It would be nice to have some closure, but obviously a project that big can be hard to get done even without complications.
Much better stuff than the earlier attempt. Good work. We find that engineers do a great job of matching the motor they offer with the controllers. We learn so much by building ourselves. I hope your son has a ton of safe fun!
I love your attitude. And it makes me feel better about MY projects and my failures. Too many youtube channels dont show failures and only wins. We need the whole process!
I am making my final project on designing a battery pack for an R electric motorbike (27s-24p) and I can really feel your pain. Isolating electrically while maintaining cooled and assembled the whole mess of cables and boards is crazy. If I only could have access to technology like tesla have hahaha
the copper wire wicks away heat too effectively. I worked a job where we occasionally recycled that stuff, it was a pain to melt so I could get an assay on it as we used a modified welder setup to melt samples down in a crucible
The fact that you had so many fails and pressed on, while explaining everything, means I want to watch more. So tired of the magic one two three done videos where "I didn't even measure, it just worked". Thanks for the awesome content!
i'm only two minutes in and i'm in awe at the editing of this video. i have to remember to care about the project too. the editing is distractingly good
Two things... 1) I wish more people had the attitude "that's not a waste because I learnt a heck of a lot" 2) I think it's great that you are building a go cart for your kids 7th birthday...
I have immense respect as a fellow engineer for someone starting out in the world of electric vehicles but I do want to mention one thing. The collective view is that anything is better than a kelly controller. I recommend looking into vesc as they are easy to program and provide much more useful information when it comes to error messages and figuring out issues with your components. If you plan on purchasing a new motor for that go-kart look for something in the 5kw range (make sure it has the correct duty cycle) and remember: electric components are limited by heat. If you find a way to cool down your motor, whether it be via a fan or water cooling, you can push your components a heck of a lot harder than spec. Also, If you have issues with your BMS and I recommend purchasing a charger such as a D6 duo that only needs the positive and negative cables (plus balance leads) to charge. It acts as its own BMS for charging and is very safe and highly intelligent. For discharging you can buy voltage testers for the balance leads and set them to warn you when the voltage drops to a low level. Voltage testers are usually 25 cents a pop and reliable in my experience. Also, voltage sag should affect a controller's performance unless there is an issue with it.
I have immense respect as a fellow editor and would like to point out the aesthetically delicious bead seams on the second battery box especially under that yellow paint. In addition, his fanciful sense of farcical, self depreciating comedic timing and melodical approach to jump cuts via utilizing foreground foley to cue spontaneous riffs brings his already premium STEM content to a higher level of infotaining/pleasurecational quality.
Why not go with a 20 kw motor so adults can have fun too, 5kw is better for a scooter or small motorcycle. I'd rather limit it than not being able to go hard enough:D
@@TheBozn If properly cooled 5kw is enough to have a great time. At 20kw you would most likely be spending money on power you don't need. Also, the components to utilize a 20kw motor would push the budget to an astronomical amount.
@@reichenschaller365 20S2P LiPo (60Ah each, 120Ah total at 74V for 11kWh) = £1800 BESC G2 (100V 400A controller) = £250 25kW 120100 motor, 300A max 180A continuous, 27S maximum, ~44Nm = £250 Halve the battery (it’s sort of overkill, the cells are 6C continuous so you can get 360A which is ample) and the cost is only £1500. Hardly astronomical for 25kW I’d say.
@@imperialsecuritybureau6037 I would love to see where you can get a 25kw motor with an appropriate duty cycle for one ~$350. $2477 for the batteries makes sense but 350 for the motor and the controller is ridiculous. If you see a 25kw motor for 350 you should steer clear of that obvious lie. Remember, in applications like a go-kart duty cycle is imperative lest you want a burnt-out brick.
I love the failure of this so much- because now I know I’m not the only one to dump days into something and still have my plan fall through. You are now my spirit animal
Thank you for addressing the fact that everything you were saying about Australia were just stereotypes and not what we are actually like. Really appreciate it, and keep up the good work with your projects.
I made a crappy spot welder using a 12V leisure battery and sharpened copper rods, and a high current relay that I controlled with an Arduino and foot pedal with precision timing to get the welds that looked best. After getting the microtiming dialled in, it worked amazing. Only trouble is, the battery losing voltage after many welds and the microtiming had to be extended to get an equivalently good weld but hardly a complaint, I can just charge it. Hope you got it sorted in the end!
Robert, you are a comedic genius! Your nord VPN ad flowed so well in the video that I wanted to watch it, and enjoyed every bit of it. All of your content is great! Thank you for going out of your comfort zone and putting in the work to bring us this great content, I'll watch anything you film, edit, and post!
I was just thinking, I'm pretty sure everyone who uses TH-cam has already seen an advert for Nord VPN, But this was the first I didn't feel tricked into watching. :D
Aging Wheels + Dankpods is the most unexpected but also the most perfect crossover. The question is, when are we going to see the Maluch on this channel?
This is my first and, at the moment, of this comment, my only Aging Wheels video; I cringed at the humor; I smirked at the dryness; I straight laughed out loud; and I learned exactly what I needed to learn. I enjoyed the video almost as much as I did at making that run on sentence.
When i built an 80A battery pack for my ebike, i did series connections with the same solid nickel strip, then soldered short lengths of copper wire to the parallel connecting nickel strip in the gaps between the battery spot welds. Works a treat!
Yep. The weak point is the tiny spot welds anyway, rather than the strips. You need lots of welds per cell, so sometimes two strips of nickel gets you some more spotting surface.
I love the thumbnail. The Tavarish-like arrows (including one pointing to dirt), you laying on the ground with a silly face, the selfie remote in your hand just out of frame... It's glorious.
I have to wonder if the hall effect sensors have a functional 'voltage/magnetic range' of input on them. Meaning, how much electricity can you put into the alternator before the resulting magnetic output overloads the HE sensor and gives a bad motor controller reading. In simpler terms, are you EMP-ing the HE sensor and therefore overloading the inputs on the MC? Cursory, completely ignorant, searching indicates sensor power voltages and switching currents range from 3-30v and 1.5ma to 250ma. Not sure what those ranges mean, but I suspect they're related to the HE error you're getting. Additional research reqd.
I'm mostly commenting in the hopes of visibility for your comment and I know nothing about this topic but your explanation would certainly make sense as this issue occurs when applying over "bare minimum" of power. Also, shouldn't it be possible to test it by accelerating slowly on flat ground? If I understand correctly, when the motor draws enough current to make the magnetic fields big enough, it happens at a point which should always be the same speed if tested multiple times under identical conditions? Am I even remotely correct?
@@jokumukamikalie You're mostly there for non-technical talk (I'm not much above that myself). It would be a good test to try, yes. Start on flat and level ground and gradually increase throttle. If it cuts out at a consistent throttle ask, then it may be as I suspect. If not, it is likely some other electrical issue. I'd start with small diameter wiring on up. Interference maybe??? I understand that he needs a break from it currently, so we may not see anything there for a while. If a patreon post comes up in future one of us should mention it (if we recall).
Hey! You should consider a cheap $60 TAV30 Torque Converter. I built a mini motorcycle bicycle using a Harbor Freight 2hp Engine. That Torque Converter made a HUGE difference in low end/high end torque!!! (BTW to fit the thing I had to buy a shim for the crankshaft which was an easy fix) good luck!!!
That may be necessary due to the alternator windings, wound for a device typically spinning at 2500+ RPM and low voltage/high current. Why do they call those "torque converter"s? It's a belt-type CVT with a centrifugal clutch. I mean, yeah it swaps torque for RPM like any transmission. Maybe my question should be "why do they call those hydraulic turbine things 'torque converter's when they aren't actually transmissions?"
As someone who has built my own e-bike, I feel your pain. Especially with the battery pack, which for me has been a constant subject of redesigns and troubleshooting and never being quite satisfied. I will say though that I used a hub motor I got from the UK, it's been serving me for 4 years and at least 10000 kilometers, and it has never given me any trouble. I'll also say that hooking up a DC to DC converter to the BMS has given me trouble, it introduced a weird feedback loop which has almost fried my BMS without any actual load on it. Electricity can get up to all kinds of weird stuff like that.
The addition of a 3d printer and cnc router is a game changer for this channels projects. Great video as always and I really enjoyed the extra time put into the "ad".
This is great - most youtube stuff is "I made this and it went perfectly first time, look how I did it in 12 seconds thanks to editing". Watching the struggle is a nice reality check
I watched your previous video about the alternator it was amazing, your extremely smart and i really like how you show when something you design didn’t work out.
5 minutes in and I can't decide if I'm more impressed by the editing and production or the sheer amount of effort put into that battery box! Brilliant 😀
I love your videos. It's so refreshing see someone not know what to do 100% and how they figure out how to make it work. I get so burned out on videos that are essentially instruction booklets lol. I need some drama, some "whoops!!" 😂, I need growth 😂😂. I love how you create things. Really awesome.
If you're ever intesterested in adding more safety to the go-cart, you might be able to add some form of cutoff in the seat belt (when the belt is buckled, allow throttle input), or a safety cutoff in the seat (similar to a lawn mower). My two cents.
Oh my goodness! That was a ride!! Good luck with it whenever you come back to it. The only thing I’d suggest is that you mount the battery pack to the frame of the kart rather than on the rear axle, then it will have a bit more cushion from bumps and rattles etc.
There needs to be a crossover with you and Adelaide local celebrity DankPods! He’s got a garbage box car he’s working on on his second channel, just sayin I smell a collab, and stinky headphones
an alternator rated for way under your voltage will screw stuff up, also the heat from the voltage on those copper strips will cause the plastic to warp
As several people have already pointed out, I would recommend using a small external rotor for the hall sensors (it could be just a 3D printed disc) to avoid any magnetic interference from the stator coils. As for the battery connections, even though it must've been a lot of work, the 3D printed clamps are probably not the best idea. 3D printed parts tend to sag over time under continuous force, not to mention that even PETG will get much softer if the battery pack heats up. I understand that you want to do thing yourself and I can appreciate that but in this case, I think it would be best to have the battery pack spot welded properly at a battery repair shop. I hope you don't abandon using the alernator as a motor, I think it's a cool idea. If you wanted to take it a step furter, you could fabricate a new rotor and use permanent magnets which would probably increase the torque and efficiency dramatically. It shoud be possible to use magnets from an old hoverboard wheel if you wanted to keep the cost low. At least you wouldn't have to worry about powering the rotor coil.
if a fuse blows, theres usually a reason why. check the rectifier and the primary side switching transistors for shorts between each leg. they could have died to a transient in your power grid of just overheated, they looked pretty dry @24:32
Sounds like a perfect present when he turns 7. I admire your perseverance! I would probably just go with about 1500 watt engine with an on/off throttle and be done with it... It would be a bit jerky in some situations but would be a lot easier to build.
I love how much you fail and try again. A great example of the process of creating. This is a great video for everyone, especially kids, since this world makes them think that everything comes without effort. Never give up.
This electric go-kart series makes my head hurt. It also reminds me of my semi-frustrating childhood, where spending thousands of dollars and a couple years building something from a combination of junk yard and expensive mail order parts was somehow always preferable for the adults in my world (children of depression era farmers) than just buying something that actually works for less money. But seriously, I wouldn't have had it any other way. Teaching the kid resourcefulness and delayed gratification is a character building lesson. But I hope the kid will get to drive the car before they start high school ;-)
Lmao I was feeling that the entire time I was watching this series. Im converting a 350 into a vortec 350 out of junkyard parts and expensive mail orders and its frustrating
I’m going through the same thing with my 66 Cadillac. Ditched the carb and added throttle body fuel injection off a 91 Chevy truck. Most of that is okay, but I did a few custom things along the way like an arduino controlled radiator fan assembly. Each time I face a challenge I wonder if I should just go back to the way it was lol
@@clarkinthedark1 I took a wiring harness off of a 98 silverado 1500 and I'm putting it on my carbed 350, i modified the hell out of the harness. 0411 swapped ecu, multiport fuel injectors with multport intake. Most of it is going ok but sometimes I wonder the samething. Should've I left it how it was? I sometimes wonder that. But considering I'm going to be able to tune the hell out of my truck and have awesome fuel economy and power I think it's worth it. If you need help feel free to ask
lol yeah. ive been trying to make speakers and i finally made some 150euro speakers that work as well at 300euro speakers, and only spent 600euros on the development.
How is an old DC treadmill motor not the perfect idea? People use them all the time to turn a normal wood lathe into a variable speed wood lathe. Just needs a cheap little PWM module you can get plans for online, and old treadmills are a dime a dozen.
It is the perfect idea for a lathe or a treadmill. Nowhere near enough power for this application, plus needs dangerously high voltages (usually 150V or so DC).
Look at where the hall sensors are.... in between the iron holding the coils on the stator. Most commercial brushless motors have the hall sensor far away from the stator coils. I think what is happening is going to the bigger/more powerful controller is causing the hall sensors to trigger on the stator field and they cannot "sense" the rotor field.... Long story short, the stator field is so strong the hall sensors cannot "detect" the rotor as it rotates. Just a thought. Keep up the good work and you will get it eventually. :-)
Oh my god I love all the mistakes you're making here for the rest of us, not only that but showing us the mistakes and explaining why The mistakes are valid mistakes, this is absolutely priceless!

@@imakedookie that might reduce the overall efficiency and overheat the motor but it wont cause an immediate cutoff
I'd put money on it. Those little buggers are sensitive! Was having intermittent issues with one and the problem ended up being the trackpad on a laptop on the other side of the room.
So throw an oscilloscope on it to check the signals on a bench test? Use a portable 'scope for live testing?
Most likely an transient from the DC-DC coupling into the LV lines. Some shielded HV cables and better grounding might improve the behaviour but i would recomment a proper motor that already has the sensors as it might already have some filters or anything.

Edit: I should also mention that Kelly provided amazing product support. Send them an email and Fany will get you sorted.
Something doesn't make sense in his setup, he uses an alternator which afaik doesn't even have a built in hall sensors so unless he added them or uses a sensorless controller that wouldn't work
@@TheBlackAndWhiteCow He added hall sensors in his last video on this project. You would know this if you A) Heard him say he added hall sensors in his last video on this project, or B) Watched his last video on this project, during which he added hall sensors.
Gotcha, TH-cam failed to delete my comment for some reason because I posted it before I watched the whole part. still there's so much to fail when converting and you end up with subpar motor that wound up for low voltage and still brushed and you still have to match the correct voltage on the excitor coil, unless you do it for fun it's better to get a proper BLDC for that
This is a silly rube goldberg device that costed a fortune and doesn't work. Put a damn predator engine on it and be done with it. The kid absolutely will get over the noise. He'll come to love it and associate it with good times.
@@tarstarkusz Have... Have you been to this channel before? You think he works on stuff to get results? What a grand and intoxicating innocence. How can you be so naive? He does not own a Yugo or a Coda because they are sensible cars to own. He isn't converting a bus to a weird RV-car-carrier because that's a sensible thing to do.
It might be a longshot, but I'd love to see a collab with you and Mehdi at ELECTROBOOM to figure this out. Def need to walk away and spend some time on other projects, and I know this is sunken cost fallacy at this point, but it would be a shame to abandon this "Learning experience."
I tried (and succeeded, failed, repeated, and dismantled) a PFSense firewall project at home and it felt a lot like this one. Learned a fair bit about it, especially when I 'was in over my head'. Would not do again, but was nice to learn. Gave me troubleshooting experience.
It's an excellent learning experience for when he decides to convert the bus to electric immediately after he finally finishes it in 2042.
"I know it's the sunk cost fallacy, but it would be a shame to..." Gee, you set the trap and then walked right into it! 😊

There are plenty of people on here who will offer their advice etc. I just want to say thank you for posting two excellent videos, they were entertaining and informative, crucially they were also brutally honest - very few TH-camrs are honest and brave enough to show their failures. What I particularly liked was your approach to problem solving and analysis of the issues that arose. I think a lot of people seem to think that creating something like this is relatively easy - although you really did make it difficult for yourself by using an alternator! You've proved that's totally not the case! I look forward to seeing how you do in the next video. Thanks once again. Best Regards. Lin. UK.
You have the patience of a saint. I love your willingness to keep at a task long beyond when a reasonable person would.
I really appreciate that you also upload your "failures". I actually learn a lot from these videos. And don't consider them as failures, it's just part of the process!
At this rate you're going to have a really awesome electric go-kart for your seven-year-old.
Probably closer to 9 year old, if you see how slow some of his projects go. I'm still waiting for that bus conversion to be finished. 🤣
@@sbrazenor2 that's mean... but hey he said the bus may never happen
@@GDMHificationranpitc I was just being a ball buster. I come for the entertainment, which he's successful at. It would be nice to have some closure, but obviously a project that big can be hard to get done even without complications.

Your content is perfect for me to watch when I get home from work and I’m smoking a bowl.
Much better stuff than the earlier attempt. Good work. We find that engineers do a great job of matching the motor they offer with the controllers. We learn so much by building ourselves. I hope your son has a ton of safe fun!
As an Australian I can say that I loved your ad, the first one I haven't skipped in ages.
I love that you've printed "attention angry electrons" in German XD
It can actually mean angry electrons as well as raging electrons...
… he wrote Elecktronen ..
@@SmilingDevil lol my mind corrected it automatically
"that's over my head... literally".
LOL^2
the stupidest basic lines are the best when the delivery is excellent ;-)
I love your attitude. And it makes me feel better about MY projects and my failures. Too many youtube channels dont show failures and only wins. We need the whole process!
I am making my final project on designing a battery pack for an R electric motorbike (27s-24p) and I can really feel your pain. Isolating electrically while maintaining cooled and assembled the whole mess of cables and boards is crazy. If I only could have access to technology like tesla have hahaha
You're a good Dad for doing a lot of this for your son. I also hope some of this knowledge transfers to the other EV projects.
"If you're bothered by this mess of balance wires, don't worry. I am too!"
I hate you. Lol
Upgrade your spot welder by throwing another MOT in parallel.
Also, the two battery packs look like they could use some insulation between them 😳
the copper wire wicks away heat too effectively. I worked a job where we occasionally recycled that stuff, it was a pain to melt so I could get an assay on it as we used a modified welder setup to melt samples down in a crucible
The fact that you had so many fails and pressed on, while explaining everything, means I want to watch more. So tired of the magic one two three done videos where "I didn't even measure, it just worked". Thanks for the awesome content!
i'm only two minutes in and i'm in awe at the editing of this video. i have to remember to care about the project too. the editing is distractingly good
This is probably the first time in my life I spent two minutes on TH-cam watching an ad, and even enjoying it. Excellent work.
Two things...
1) I wish more people had the attitude "that's not a waste because I learnt a heck of a lot"
2) I think it's great that you are building a go cart for your kids 7th birthday...
I have immense respect as a fellow engineer for someone starting out in the world of electric vehicles but I do want to mention one thing. The collective view is that anything is better than a kelly controller. I recommend looking into vesc as they are easy to program and provide much more useful information when it comes to error messages and figuring out issues with your components. If you plan on purchasing a new motor for that go-kart look for something in the 5kw range (make sure it has the correct duty cycle) and remember: electric components are limited by heat. If you find a way to cool down your motor, whether it be via a fan or water cooling, you can push your components a heck of a lot harder than spec. Also, If you have issues with your BMS and I recommend purchasing a charger such as a D6 duo that only needs the positive and negative cables (plus balance leads) to charge. It acts as its own BMS for charging and is very safe and highly intelligent. For discharging you can buy voltage testers for the balance leads and set them to warn you when the voltage drops to a low level. Voltage testers are usually 25 cents a pop and reliable in my experience. Also, voltage sag should affect a controller's performance unless there is an issue with it.
I have immense respect as a fellow editor and would like to point out the aesthetically delicious bead seams on the second battery box especially under that yellow paint.
In addition, his fanciful sense of farcical, self depreciating comedic timing and melodical approach to jump cuts via utilizing foreground foley to cue spontaneous riffs brings his already premium STEM content to a higher level of infotaining/pleasurecational quality.
Why not go with a 20 kw motor so adults can have fun too, 5kw is better for a scooter or small motorcycle. I'd rather limit it than not being able to go hard enough:D
@@TheBozn If properly cooled 5kw is enough to have a great time. At 20kw you would most likely be spending money on power you don't need. Also, the components to utilize a 20kw motor would push the budget to an astronomical amount.
@@reichenschaller365 20S2P LiPo (60Ah each, 120Ah total at 74V for 11kWh) = £1800
BESC G2 (100V 400A controller) = £250
25kW 120100 motor, 300A max 180A continuous, 27S maximum, ~44Nm = £250
Halve the battery (it’s sort of overkill, the cells are 6C continuous so you can get 360A which is ample) and the cost is only £1500. Hardly astronomical for 25kW I’d say.
@@imperialsecuritybureau6037 I would love to see where you can get a 25kw motor with an appropriate duty cycle for one ~$350. $2477 for the batteries makes sense but 350 for the motor and the controller is ridiculous. If you see a 25kw motor for 350 you should steer clear of that obvious lie. Remember, in applications like a go-kart duty cycle is imperative lest you want a burnt-out brick.
I love this project, but I also understand that you might now wanna continue it. But it would be so so so fun to see you succeed and get it working!
I love how you show your mistakes, it makes the video so much more personable!
I love the failure of this so much- because now I know I’m not the only one to dump days into something and still have my plan fall through. You are now my spirit animal
Caution! Angry electrons! :D
Love that one :)
And since it doesn't matter really, I'll shush about "Elektronen" only having a k instead of a ck ;-)
I even like "Elecktronen" more 😁
LOCAL CELEBRITY DANKPODS?!
MY BOY MADE IT! I'M SO PROUD!
Thank you for addressing the fact that everything you were saying about Australia were just stereotypes and not what we are actually like. Really appreciate it, and keep up the good work with your projects.
I've learned so much just from this video. Thank you. On a sidenote: This was the most fun ad for NordVPN I've seen so far.
Your self deprecating yet tenacious approach is so refreshing and inspiring. Makes the rest of us feel like we can do hard things too.
I just have conversations with myself in my head. Aging Wheels actually acts them out. A whole new level of crazy.
I absolutely love the editing you do, and i find your humor to be highly entertaining!
I made a crappy spot welder using a 12V leisure battery and sharpened copper rods, and a high current relay that I controlled with an Arduino and foot pedal with precision timing to get the welds that looked best. After getting the microtiming dialled in, it worked amazing. Only trouble is, the battery losing voltage after many welds and the microtiming had to be extended to get an equivalently good weld but hardly a complaint, I can just charge it. Hope you got it sorted in the end!
My son and I loved watching these two videos! I am also super jealous of that welded battery box, looks awesome!
Maybe the son can help with the project. Once he has finished school and university and is a engineer of some kind. :)
Ah, we finally have a sequel to Project Binky
@@chrisestill8825 is this not project binky? Oh God, where am I?
Robert, you are a comedic genius! Your nord VPN ad flowed so well in the video that I wanted to watch it, and enjoyed every bit of it.
All of your content is great! Thank you for going out of your comfort zone and putting in the work to bring us this great content, I'll watch anything you film, edit, and post!
I was just thinking, I'm pretty sure everyone who uses TH-cam has already seen an advert for Nord VPN, But this was the first I didn't feel tricked into watching. :D
Aging Wheels + Dankpods is the most unexpected but also the most perfect crossover. The question is, when are we going to see the Maluch on this channel?
When aging wheels drops his pkcells
Thank you for uploading you stuff to TH-cam. People like you are amazing.
This is my first and, at the moment, of this comment, my only Aging Wheels video; I cringed at the humor; I smirked at the dryness; I straight laughed out loud; and I learned exactly what I needed to learn.
I enjoyed the video almost as much as I did at making that run on sentence.

When i built an 80A battery pack for my ebike, i did series connections with the same solid nickel strip, then soldered short lengths of copper wire to the parallel connecting nickel strip in the gaps between the battery spot welds. Works a treat!
Yep. The weak point is the tiny spot welds anyway, rather than the strips. You need lots of welds per cell, so sometimes two strips of nickel gets you some more spotting surface.
I love the thumbnail. The Tavarish-like arrows (including one pointing to dirt), you laying on the ground with a silly face, the selfie remote in your hand just out of frame... It's glorious.
I have to wonder if the hall effect sensors have a functional 'voltage/magnetic range' of input on them. Meaning, how much electricity can you put into the alternator before the resulting magnetic output overloads the HE sensor and gives a bad motor controller reading. In simpler terms, are you EMP-ing the HE sensor and therefore overloading the inputs on the MC?
Cursory, completely ignorant, searching indicates sensor power voltages and switching currents range from 3-30v and 1.5ma to 250ma. Not sure what those ranges mean, but I suspect they're related to the HE error you're getting. Additional research reqd.
I'm mostly commenting in the hopes of visibility for your comment and I know nothing about this topic but your explanation would certainly make sense as this issue occurs when applying over "bare minimum" of power. Also, shouldn't it be possible to test it by accelerating slowly on flat ground? If I understand correctly, when the motor draws enough current to make the magnetic fields big enough, it happens at a point which should always be the same speed if tested multiple times under identical conditions? Am I even remotely correct?
@@jokumukamikalie You're mostly there for non-technical talk (I'm not much above that myself). It would be a good test to try, yes. Start on flat and level ground and gradually increase throttle. If it cuts out at a consistent throttle ask, then it may be as I suspect. If not, it is likely some other electrical issue. I'd start with small diameter wiring on up. Interference maybe??? I understand that he needs a break from it currently, so we may not see anything there for a while. If a patreon post comes up in future one of us should mention it (if we recall).

Hey! You should consider a cheap $60 TAV30 Torque Converter. I built a mini motorcycle bicycle using a Harbor Freight 2hp Engine. That Torque Converter made a HUGE difference in low end/high end torque!!! (BTW to fit the thing I had to buy a shim for the crankshaft which was an easy fix) good luck!!!
That may be necessary due to the alternator windings, wound for a device typically spinning at 2500+ RPM and low voltage/high current.
Why do they call those "torque converter"s? It's a belt-type CVT with a centrifugal clutch. I mean, yeah it swaps torque for RPM like any transmission. Maybe my question should be "why do they call those hydraulic turbine things 'torque converter's when they aren't actually transmissions?"
Your humor keeps me coming back video after video. Definitely one of the best TH-camrs. I really like your other channel too
As someone who has built my own e-bike, I feel your pain. Especially with the battery pack, which for me has been a constant subject of redesigns and troubleshooting and never being quite satisfied. I will say though that I used a hub motor I got from the UK, it's been serving me for 4 years and at least 10000 kilometers, and it has never given me any trouble. I'll also say that hooking up a DC to DC converter to the BMS has given me trouble, it introduced a weird feedback loop which has almost fried my BMS without any actual load on it. Electricity can get up to all kinds of weird stuff like that.
The addition of a 3d printer and cnc router is a game changer for this channels projects. Great video as always and I really enjoyed the extra time put into the "ad".
This is great - most youtube stuff is "I made this and it went perfectly first time, look how I did it in 12 seconds thanks to editing". Watching the struggle is a nice reality check
Really like that you also show what did not work as intended. And then problem solutions that might help the error.
I watched your previous video about the alternator it was amazing, your extremely smart and i really like how you show when something you design didn’t work out.

5 minutes in and I can't decide if I'm more impressed by the editing and production or the sheer amount of effort put into that battery box! Brilliant 😀
The sponsor bit.... I am over my head in love with this channel
I love your videos. It's so refreshing see someone not know what to do 100% and how they figure out how to make it work. I get so burned out on videos that are essentially instruction booklets lol. I need some drama, some "whoops!!" 😂, I need growth 😂😂. I love how you create things. Really awesome.
Apart from the project I just must comment on the absolutely best sponsor plug ever! Editing is awesome also.
what a crazy time line. I love seeing the hair cut before and after parts.
If you're ever intesterested in adding more safety to the go-cart, you might be able to add some form of cutoff in the seat belt (when the belt is buckled, allow throttle input), or a safety cutoff in the seat (similar to a lawn mower).
My two cents.
I'd put some protection between the chain and the high current cabling personally...
Oh my goodness! That was a ride!! Good luck with it whenever you come back to it. The only thing I’d suggest is that you mount the battery pack to the frame of the kart rather than on the rear axle, then it will have a bit more cushion from bumps and rattles etc.
brooooo ... feel ya frustration! Happy you kept at it. Good luck and look forward to you FINISHING this project.
Quality video and editing ❤
There needs to be a crossover with you and Adelaide local celebrity DankPods!
He’s got a garbage box car he’s working on on his second channel, just sayin
I smell a collab, and stinky headphones
Let's get some scarlet fire on there
Yess this needs to happen!
an alternator rated for way under your voltage will screw stuff up, also the heat from the voltage on those copper strips will cause the plastic to warp
As several people have already pointed out, I would recommend using a small external rotor for the hall sensors (it could be just a 3D printed disc) to avoid any magnetic interference from the stator coils. As for the battery connections, even though it must've been a lot of work, the 3D printed clamps are probably not the best idea. 3D printed parts tend to sag over time under continuous force, not to mention that even PETG will get much softer if the battery pack heats up. I understand that you want to do thing yourself and I can appreciate that but in this case, I think it would be best to have the battery pack spot welded properly at a battery repair shop. I hope you don't abandon using the alernator as a motor, I think it's a cool idea. If you wanted to take it a step furter, you could fabricate a new rotor and use permanent magnets which would probably increase the torque and efficiency dramatically. It shoud be possible to use magnets from an old hoverboard wheel if you wanted to keep the cost low. At least you wouldn't have to worry about powering the rotor coil.
I am just 10 min in, will finish don't worry. But it is absolutely clear from here that your script and your editing are stellar. Kudos, man.
if a fuse blows, theres usually a reason why. check the rectifier and the primary side switching transistors for shorts between each leg. they could have died to a transient in your power grid of just overheated, they looked pretty dry @24:32
You never truly understand a concept until you can explain it to laymen. Good job Mr Dunn.
Sounds like a perfect present when he turns 7. I admire your perseverance! I would probably just go with about 1500 watt engine with an on/off throttle and be done with it... It would be a bit jerky in some situations but would be a lot easier to build.
You did GREAT! Thank you for documenting the process, the failures, the upgrades etc.
Thanks for the Knowledge and Laughs I've gotten from your Videos.
I love how much you fail and try again. A great example of the process of creating. This is a great video for everyone, especially kids, since this world makes them think that everything comes without effort. Never give up.
This electric go-kart series makes my head hurt. It also reminds me of my semi-frustrating childhood, where spending thousands of dollars and a couple years building something from a combination of junk yard and expensive mail order parts was somehow always preferable for the adults in my world (children of depression era farmers) than just buying something that actually works for less money. But seriously, I wouldn't have had it any other way. Teaching the kid resourcefulness and delayed gratification is a character building lesson. But I hope the kid will get to drive the car before they start high school ;-)
Lmao I was feeling that the entire time I was watching this series. Im converting a 350 into a vortec 350 out of junkyard parts and expensive mail orders and its frustrating
I’m going through the same thing with my 66 Cadillac. Ditched the carb and added throttle body fuel injection off a 91 Chevy truck. Most of that is okay, but I did a few custom things along the way like an arduino controlled radiator fan assembly. Each time I face a challenge I wonder if I should just go back to the way it was lol
@@clarkinthedark1 I took a wiring harness off of a 98 silverado 1500 and I'm putting it on my carbed 350, i modified the hell out of the harness. 0411 swapped ecu, multiport fuel injectors with multport intake. Most of it is going ok but sometimes I wonder the samething. Should've I left it how it was? I sometimes wonder that. But considering I'm going to be able to tune the hell out of my truck and have awesome fuel economy and power I think it's worth it. If you need help feel free to ask
lol yeah. ive been trying to make speakers and i finally made some 150euro speakers that work as well at 300euro speakers, and only spent 600euros on the development.
How is an old DC treadmill motor not the perfect idea? People use them all the time to turn a normal wood lathe into a variable speed wood lathe. Just needs a cheap little PWM module you can get plans for online, and old treadmills are a dime a dozen.
It is the perfect idea for a lathe or a treadmill. Nowhere near enough power for this application, plus needs dangerously high voltages (usually 150V or so DC).
This is an effort. I like you for your toughness! And the sponsor segue...
your humour, wit, and editing were amazing! keep it up
This ad was the best one i have ever seen! It made watching ads fun again! Thanks! 😁

Even if he was lousy at making stuff, which he isn't, I would watch just for the editing cuts.
Look at where the hall sensors are.... in between the iron holding the coils on the stator. Most commercial brushless motors have the hall sensor far away from the stator coils. I think what is happening is going to the bigger/more powerful controller is causing the hall sensors to trigger on the stator field and they cannot "sense" the rotor field.... Long story short, the stator field is so strong the hall sensors cannot "detect" the rotor as it rotates. Just a thought. Keep up the good work and you will get it eventually. :-)
Oh my god I love all the mistakes you're making here for the rest of us, not only that but showing us the mistakes and explaining why The mistakes are valid mistakes, this is absolutely priceless!
