As a guy who designs electrical things as the day job, the time you took to do each wire and connection right is what I love to see in the field. Excellent craftsmanship all around. You used the right tools and took the right time to do it right. I have really enjoyed this build and level of detail you put into it. Like you mention, 100s of hours per video.
My brain hurts thinking about how you were able to put this massive puzzle together. I can't believe you finally were able to take it for a drive! Congratulations!
@@JerryRigEverything I remember the feeling of the first test drive on a electric sk8board that I've build and customized. Your humvee is something else. I hope it will give you much more smiles per kWh than headaches.
I just replaced the batteries in my remote control and I feel like a champ. Hopefully the feeling for you getting this done is similar lol. All kidding aside, great job man and someone needs to sponsor you to bring this bad boy down to CES one year.
It’s more terrifying to remove and recharge 6s lipos in a rc car. Those things have like no regulations and could go thermonuclear at any moment. Even just sitting on a shelf.
Maybe it's already been mentioned somewhere or maybe someone else has made the comment, but I'd really suggest putting a driveshaft safety loop or two on the rear shaft. Any failure of a driveshaft component at speed and that shaft will start whipping around in the tunnel with enough energy to rip into those battery boxes pretty quickly.
I've mentioned this on every episode he drops. When that shaft lets go, his hummer is going to burn to the ground. I hope he is able to get out before it gets too hot.
Idk what that thing is but someone mentioned something in a about that a thin metal plate he used to attach driveshaft (?) or something to the body of humvee & they pointed out that metal plate can't possibly handle the torque produced by this. Are you guys talking about the same thing?
you should copy paste this comment and comment it on his newly posted video very fast and early so that he can see this important suggestion that can save his hummer from burning.
it is exactly the sound the morning milk man's delivery float used to make when i was a child, they were electric and largely disappeared before the turn of the centaury in the uk
That high pitched noise is probably FOC - “Field Oriented Control”. It’s a method for controlling motors at slow speeds and many controllers switch it off at a steady state. Your motor controller probably has some configuration around this, you have a lot of inertia so once your moving you can probably shift over - experiment with the cutoff to get lowest noise / smoothest acceleration.
For something with the weight of a standard ICE hummer 20 kmph (16mph-ish) for the acceleration to switch to a higher speed. That's the maximum I'd say, could easily even go for half that. It's mostly a setting of "how fast are you going to go offroading to the point your motor can't push at standard settings?"
I am willing to bet, that it runs on Vector control (FOC) over the full range. The whine comes from motor coil resonance due to switching frequency. At low speeds the PWM signal is at low duty cycle, which creates a rather drastic change in magnetic flux in the coils, which in turn makes them vibrate.
It is probably running FOC, though it is usually not turned off to my knowledge. But there is usually a high frequency injection happening (at least with sensorless FOC) at low speeds to estimate the direction of the rotor. At higer speed it is not needed since the induced voltage from the magnets (into the windings) are much bigger than any other voltage drops and can therefore be used to estimate the direction of the rotor. But it could also be an inverter with variable switching frequency as @Veselin Georgiev says.
24:40 THAT was funny! I smiled a lot through this video- SO excited and happy for you! YOU DID IT!!! I knew you would, but I also knew what a huge undertaking this would be. Those shirts are deadly! I gotta get one!
I'm amazed Jerry has been able to put this much time into projects with a newborn. Mind you, it's not just a "this'll be cool", it IS a large part of their income stream. Me, I was chuffed that I built a 3 foot aquarium & wooden stand during my wife's pregnancy with our first, it was my "stay out of her way and let her rest" project.
The high pitched whine that they were talking about is the DC braking feature of the motor controller. It's applies a PWM signal to the windings of the motor to hold it in position when momentum, gravity, or some other force is causing it to move when you're telling the motor to stop. High frequency switching (PWM) makes noise because of efficiency losses (sound, heat, light, etc.).
@@florrieflorrie4577 I'm not sure what sort of methods Tesla or BMW employs for their motor controllers. They could be using regenerative braking. Depending on the gearing or noise dampening involved, this can be relatively quiet. The DC braking that I think was used here can also be quieter. When they close up the hole in the cabin that goes straight to the engine compartment it should dampen it. High frequencies don't penetrate walls as easily as low frequency.
@@Drag0nmaster yeah that thing even with sound dampening is gonna sound loud as hell. Not as loud as a diesel etc but still loud because he’s got balloon style 33s 35s so that makes it louder, then the wind noise and basically sheet metal panels that vibrate like crazy at higher speeds, it will be miserable for good drives
I'm loving every single episode of this series! And I really hope he can come up with another project once he's done with this one because I'm quite addicted right to this series right now and I can't believe it's almost over!
In would like to see some Cambry in these episodes. Being a bit of a DIY dude myself (I built my house along with some other projects) I have followed Zach for some time. When Cambry came into the picture she added a nice colour to everything. I like the episodes where she appears as much as all the technical stuff.
Yeah. I agree. . . Maybe a project thats an extension of this one. Like a sport or camping trailer that goes with the Hummer. That way we get to paint it with matching colours. . . TGC Blessings:)
Generally, when you assemble high power electrical leads, it is good practice to mark the mounting hardware, so that you know it has been properly torqued and it hasn't moved. Loose joints can create cool fires 😁 Also that whine you hear is coil whine from the motor. You can try to change carrier frequency of the inverter to minimize it.
I am seriously impressed. To go from being generally good at tech and mechanics to actually putting together such a complex piece of hardware as an EV, thats a feat for sure. Kudos to you Jerry.
THIS by far is the most satisfying episode of the whole journey so far!the intricacies of assembling each of the batteries into place n loading em up into the humvee....super satisfying!the thrill n suspense when u got it rolling surpasses my excitement for all the Jurassic Park movies dino scenes...i really feel like been part of the project,so yeah-i'm grabbing the Whisper Tees for sure!
Honestly, each one of these videos, for me, is the most highly anticipated thing on RUclips. The sense of satisfaction and fulfillment Jerry must feel all throughout this process can’t possibly be overstated. And really, imagine once this whole thing is buttoned up and fully functional; what can he not do then?
Working, myself, on a relay setup for a rock crawler with 32 relays and fuses, I have been almost overwhelmed by the learning curve of rewiring the entire vehicle. This project blows me totally away, and really provides inspiration. Congratulations, you deserve all of the thrill of that first drive.
That 3 AM test drive of a project never gets old lol. Also, that whine sounds like the PWM frequency of the speed controller/inverter, it might be switching drive modes at different speeds? Should be able to be tuned out with some settings. From my experience ESCs tend to do that when they're running in sensorless mode. I assume that motor has an encoder but it may need some configuring.
You should probably install a steel hoop around that drive shaft to keep it from smacking the center battery box. If a universal joint breaks it could get ugly
I found myself grinning from ear to ear when you all drove through the parking lot. What an undertaking. This is the best build series on RUclips right now.
You should put a couple driveshaft loops on it to prevent damage to the center box if you were to ever have a u joint failure. Hate to see it burn to the ground due to a battery venting. Great work! Love the series!
I believe the reason the motor makes that high pitched sound when it starts from a stop is the ESC in a special high torque mode that pushes more current to the motor, similar to the sound hybrid cars make when they start rolling. It's sort of like a first gear.
@@DavidBezemer indeed it is. It may be possible to increase the pwm switching frequency in the inverter, to push the noise out of human hearing. This is certainly possible with commercial VFDs.
Man I'm so happy for you! I work as an electrical designer for an EV company its amazing to see that the information is available for anyone in the world to give this a try if need be! Amazing job again and Im looking forward to seeing how much further you take it!
i just want to say how much I appreciate you naming all the things like Canon plug with 31 holes and letting us know its called HD30. So many people that build and do cool things on youtube channels don't really give us details if we ever want to do anything on our own. Thanks!
I'm not even driving it but still it makes me crazy happy to see this project come along such a long way...I've been waiting for this day since the first video was uploaded and got me crazy excited about how a converted HUMMER EV would really be like. I've followed this project more than any show that exists and honestly I really got addicted to this series like I've watched each and every video in literally less than an hour every time they were uploaded....Congratulations to Zack his family and the whole team that's been working really hard on this project. Would love to see the HUMMER EV in SEMA 2022. Much Love ❤
When it first came out of the garage on its own power, I screamed of excitement! And I'm not even part of the build. Haha! What you did is super cool stuff! Congrats!
I think that this humvee build series deserves an award or some sort of recognition. Alot of effort were put into this. Also, will this be street legal once finished?
I was wondering that, too. But then again, it's the US, so if it rolls n breaks, it's probably street-legal :-D I know in Germany it's very difficult to get a license plate for any kind of EV conversion as you have to get it examined by an official authority, which is quite expensive. And if you fail the examination, you have to fix the issues and redo the process, until you pass everything. It can end up costing many thousands of euros just to get a permit to run on public roads... And if you are not an expert in what you are doing it will be very difficult to build an EV up to code in the first place. Every wire, fastener, connector, mount, etc is tested and has to be up to code in its own right. It's not an easy process. It's all in the name of safety though, and I think it's ok. Sucks that you can't easily convert your own car. But prevents unsafe cars to be on the road. So overall, I am not too mad about it.
U should install an outlet (and prolly some sort of inverter or converter on ur wall idk exactly how it works) to output power so that you could actually use it to run a house for a few days maybe even a some sort of charge controller to hook it up to the solar panels u installed a while back
Nice job Zack! 2 things 1. Spraying that centre box with some bed liner for protection could be a good idea. 2. Some catch loops for the drive shaft. If it breaks loose with no restraints it will either thrash like hell against the centre box, or your Hummer's rear end will try to do the pole vault as the front of the drive shaft ploughs into the road.
Being a mechanic who operates a family business I'm really excited by the future of electrification, alot of people assume I'm against it because keeping liquid drinking jalopies on the road is a major part of my lively hood, it's exactly the opposite, I would gladly trade dropping compact electric motors into vehicles instead of piston pumping greaseballs 😂
@@man_imbored171 regular cars are definitely alot harder to repair these days, many more moving parts that have individual sensors for each component, electric motors having a single moving part is definitely a plus
Followed this project from the first video. Going through an engineering school right now, there are often moments were I think the task at hand is impossible. Just a lot of input in a short amount of time paired with high expectations. Then I remember that guy from RUclips, who DIYs an EV conversion in his garage and that really puts stuff into perspective. You're an inspiration, Zack, thanks for taking us along for the ride.
hi Jerry, i saw your coolant routing at 3:28. You might swap the direction of one of those stainless steel pipes, because you are cooling the right battery way more efficient than the left one. This is due to the pressure taking the easiest way through the system. like in the early 1991 Mazda NA Miatas. Greeets from germany, keep it up!
Words can't explain how much I love this series, I have been waiting for every new video like it's a TV show This might just be the most important project on RUclips.
The way jerry present everything .. the little details..Its awesome...we should promote these types of knowledge ....not the shit most RUclipsrs present in their vlog.
Jerry, the hole drilled through the middle position of the metal section severely compromises the structure of the member that joins the chassis perpendicularly from side to side of the Humvee. You should look out for some flex or accelerated failure by the thinned out material there. 16:00.
I think it should be ok. The hole would reduce shear capacity mostly. The majority of bending capacity is provided by the top and bottom flanges which are intact and so there shouldn’t be much if any additional flex. I would be more concerned if the top and bottom of the section are cut.
As we did in the cabin of the boats at Night you use a low wattage RED blub to light up the cabin so we cab see somewhat outside...As the military does as well to help you see better at night does not overpower ur irris with white light.....
Out of everything that is just plain amazingly awesome and high-tech, what I love most is how clean everything is on fitment and presentation. It is a piece of art, like each piece was specifically designed for this one purpose. Amazing job Zack!
This has been one of my favorite series. After it's finished I would love to see this traveling around and making appearances on other shows to bring more traffic to your channel. I can definitely see this showing up on MKBHD and Lew Later. Thoughts? If not grab a huge sponsor and take it to major cities for meet and greets and show it off.
Been following and admiring this series for a while that I actually felt the happiness of completion! For the last 5 minutes I was smiling like an idiot to the screen
The drive shaft underneath the centre boxs need to be a little more secure i think by making a tube chassis type of thing around it,just to be safer if the shaft breaks or something
@@JM-oi9pk You're more than welcome to make your own electric Humvee and get it to run quieter as your Tesla. Until then, leave the room so the adults can talk.
For the under dash wiring you should do wax cable lacing like aircraft use. Does sheaves that cover wire some times rub over time and ware a hole in the wires.
The most unique beefy and technically well thought out electrified conversion ever seen on RUclips! I take my hat off to your ingenuity and forward thinking throughout this epic build! 😃👍
This was one of the most satisfying videos to watch in this series, yet!.. and not just because of the major milestone but also for all the detail in how those battery boxes are constructed. Impressive. Congrats!
Been watching this project since day one. The amount of hard work and dedication you put in this really paid off, i am more than happy for your success. Congrats!
I've been here for learning, but who am I kidding. I have been here to see Zack's excitement once this baby starts rolling. Paid off! MASSIVE MASSIVE RESPECT.
The day He started this project I wasn’t sure how the things will come together, but then I watched every single episode of this project and things were much clear ! As I software engineer I can understand how joyful it’s when you are done with a project and it works, Congratulations Zack
Jerry I hope you get a chance to take this beast for some serious off-roading someday! Imagine enjoying nature without diesel pollution in the future, everyone wins 👍
as an engineering student this project is so fascinating and watching your videos for this series for twice or thrice like a kid watching cartoons 😅 and also I can almost feel wind through my hair as the Hummer is started 🔥
“Overkill is a good thing” This is the difference between engineering on the fly and engineering to make a profit. Engineering on the fly is not as financially constrained since it is based off of your cash flow. Let the project take longer and you have more money to spend on the project. Engineering for mass production means every time the design saves money that ends up being money you can spend on more features or more RnD for your next product.
Man, it all coming together is so great, it's been a joy watching this, and it was making it, you can tell. Your best project so far, and one of the most impressive YT series of the past decade. You rock Zach...
Have been waiting for this day all along and here we are.. so amazing to see this finally come together on its feet(or wheels rather ).. the entire journey has been so absorbing and equally connecting to the viewers.. i'm sure many of us started clapping around on seeing it move for the first time.. Thank You Jerry for this series and making us all part of the experience.
Awesome job! The whine is extremely annoying though, reminds me of some of my RC cars, in rc it is usually fixed by adjusting PWM settings, not sure if it applies here. My current RC powered by sensored BLDC motor with foc control is completely silent and so is my sur ron ebike, so there must me solution out there, keep up good work!
Awesome Build!. "If it's worth engineering, it's worth over-engineering!" I laughed, that after you have put so much time and effort into the project, you still seem surprised and excited that it actually works. Best feeling in the world, that sense of achievement on the first drive of a new project vehicle. Keep up the good work. ;-)
this guy made an entire electric truck and companies are struggling even after launching before this guys started working on this project. I am following JRE, may be just because of this project, but I have to say this series is the best one you can find on the RUclips for any DIY stuff. respect man!
23:10 if you dont have rubber liner on the metal holes in the hummer Id suggest to add as a precaution even if the rubber liners of the cable are thick
Love this series so much. I’m very interested to know what the final front/rear weight balance will be! And how it roughly compares to the original balance. Keep it up Zach!!!
Congratulations! I have been with you since you brought the hummer home and with you as you got the hummer turned into EV! looking forwards to build progress.
Hey zack, i know its still a long way to go before this is anywhere near complete - but is it possible for you to put up a graphic (either in a video, or elsewhere) that shows the breakdown of what you are installing into the hummer and where it goes? like top down view of the hummer with the engine and ESC in the front, ecu somewhere in the middle, 12v system in the passengers seat, batteries in the back, and what ever is going out the back of the batter box etc? maybe if you 'have the spare time...' mark what things you have done etc - just something to help everyone follow along with what is a very complex conversion for most people to 'just know' where everything goes or what is needed?
Idk if it's just me but as watching this I felt so chill like just to the point I almost fell asleep all the sounds of drilling and tapping etc.. and Zack's voice is so calming to top it off. The only thing that kept me awake is how cool the build is and how it's going.
Such a brilliant series Zack! I wait so eagerly for these!! Couple of questions 1. The metal box is so tightly enclosed (including water seal) but the front portion seemingly has a gap? Was this explained somewhere in case I missed? 2. What are your thoughts on that metal box not being easy to tear apart? What is some battery module dies, wouldn't the replacement be super hard? 3. Thanks for mentioning the whining noise. When in your previous video you had it installed, I saw no comments and thought I am the only one hearing the tinnitus like whine. Is it from the inverter? 4. Are there sensors inside battery enclosures that does monitoring for you and show alerts?
I'm pretty sure the whining is due to the inverter. Actually the noise itself probably comes from the motor but it's because of the inverter switching. Other electric vehicles definitely make the same noise.
@@wolfgangornig3556 ahhh I see the o ring when he shows the breather at the start just not when screwing it in! Still not sure about the o ring threads or the big hole in the top of the box though
We've got a roller! "Amazing work" doesn't even come close to describing this. Loved every minute of this series, and I mean what's not to love, been smiling like an idiot seeing it move under its own power. 💖

Also Zack: “I am not a smart person”
The humbleness 😂
Fr lol
🤣lol
Everyone who hasn't built an entire electric vehicle: "what does that make me?!" O.O
He built the HMMWV part of the vehicle?
Looking forward to seeing this Hummer in person.
Wow.. Munro my man himself.
The Teardown Titan himself!!! 🔥🔥🔥
I'm sure for him it will be like having a visit from Jesus in person.
😮
Oh man... You better reduce the amount of screws and other connection points in there before Sandy sees it.
I believe the reason the motor makes that high pitched sound when it starts from a stop is the ESC in a special high torque mode that pushes more current to the motor, similar to the sound hybrid cars make when they start rolling. It's sort of like a first gear.
It's a Pulse Width Modulation (PWM) noise, most likely from the inverter.
@@DavidBezemer pretty sure yeah, although I couldn't hear the sound change from the changing duty cycle
@@DavidBezemer indeed it is. It may be possible to increase the pwm switching frequency in the inverter, to push the noise out of human hearing. This is certainly possible with commercial VFDs.
Wrong, it’s the alternator, needs new oil
@@GardenGuy1942 hmmm....I was leaning toward the muffler bearings.
Back in the day, I had to solder each wire into the cups on the back of the cannon plug pins. Tip: start from the center and work your way out.
Man I'm so happy for you! I work as an electrical designer for an EV company its amazing to see that the information is available for anyone in the world to give this a try if need be! Amazing job again and Im looking forward to seeing how much further you take it!
Those LTT zipties being used is absolutely hilarious 😂 I made a DIY eBike (72v/2500w) and used them for cable management on the bike too 😂
Congratulations to Zack and his channel: Hands-down, this is the BEST content on RUclips in 2022!
i just want to say how much I appreciate you naming all the things like Canon plug with 31 holes and letting us know its called HD30. So many people that build and do cool things on youtube channels don't really give us details if we ever want to do anything on our own. Thanks!
I'm not even driving it but still it makes me crazy happy to see this project come along such a long way...I've been waiting for this day since the first video was uploaded and got me crazy excited about how a converted HUMMER EV would really be like. I've followed this project more than any show that exists and honestly I really got addicted to this series like I've watched each and every video in literally less than an hour every time they were uploaded....Congratulations to Zack his family and the whole team that's been working really hard on this project. Would love to see the HUMMER EV in SEMA 2022. Much Love ❤
When it first came out of the garage on its own power, I screamed of excitement! And I'm not even part of the build. Haha! What you did is super cool stuff! Congrats!
I think that this humvee build series deserves an award or some sort of recognition. Alot of effort were put into this.
Also, will this be street legal once finished?
It should be there's nothing here that would make it not street legal.
I was wondering that, too. But then again, it's the US, so if it rolls n breaks, it's probably street-legal :-D
I know in Germany it's very difficult to get a license plate for any kind of EV conversion as you have to get it examined by an official authority, which is quite expensive. And if you fail the examination, you have to fix the issues and redo the process, until you pass everything. It can end up costing many thousands of euros just to get a permit to run on public roads...
And if you are not an expert in what you are doing it will be very difficult to build an EV up to code in the first place. Every wire, fastener, connector, mount, etc is tested and has to be up to code in its own right. It's not an easy process.
It's all in the name of safety though, and I think it's ok. Sucks that you can't easily convert your own car. But prevents unsafe cars to be on the road. So overall, I am not too mad about it.
U should install an outlet (and prolly some sort of inverter or converter on ur wall idk exactly how it works) to output power so that you could actually use it to run a house for a few days maybe even a some sort of charge controller to hook it up to the solar panels u installed a while back
Nice job Zack!
2 things
1. Spraying that centre box with some bed liner for protection could be a good idea.
2. Some catch loops for the drive shaft. If it breaks loose with no restraints it will either thrash like hell against the centre box, or your Hummer's rear end will try to do the pole vault as the front of the drive shaft ploughs into the road.
Being a mechanic who operates a family business I'm really excited by the future of electrification, alot of people assume I'm against it because keeping liquid drinking jalopies on the road is a major part of my lively hood, it's exactly the opposite, I would gladly trade dropping compact electric motors into vehicles instead of piston pumping greaseballs 😂
Yeah but they're becoming more and more hard to repair
@@man_imbored171 regular cars are definitely alot harder to repair these days, many more moving parts that have individual sensors for each component, electric motors having a single moving part is definitely a plus
Followed this project from the first video. Going through an engineering school right now, there are often moments were I think the task at hand is impossible. Just a lot of input in a short amount of time paired with high expectations. Then I remember that guy from RUclips, who DIYs an EV conversion in his garage and that really puts stuff into perspective. You're an inspiration, Zack, thanks for taking us along for the ride.
Love your face when the car started! i'd also had the same feeling XD
Seeing Zack happy with his Hummer is the most Wholesome thing on the web, Congratulations!
hi Jerry,
i saw your coolant routing at 3:28. You might swap the direction of one of those stainless steel pipes, because you are cooling the right battery way more efficient than the left one. This is due to the pressure taking the easiest way through the system. like in the early 1991 Mazda NA Miatas.
Greeets from germany, keep it up!
Words can't explain how much I love this series, I have been waiting for every new video like it's a TV show
This might just be the most important project on RUclips.
you might wanna watch 'Rebuild Rescue' rebuilding an abandoned airplane
The way jerry present everything .. the little details..Its awesome...we should promote these types of knowledge ....not the shit most RUclipsrs present in their vlog.
Am I the only one who was so hungry to see these wheels spinning on road. Loved the video Jerry❣. Learnt a lot from this Electric Hummer Series 💯✊🏻
This is incredible. I can't believe you've gotten this far into building the EV and I cannot WAIT for the final results!
Jerry, the hole drilled through the middle position of the metal section severely compromises the structure of the member that joins the chassis perpendicularly from side to side of the Humvee. You should look out for some flex or accelerated failure by the thinned out material there. 16:00.
I think it should be ok. The hole would reduce shear capacity mostly. The majority of bending capacity is provided by the top and bottom flanges which are intact and so there shouldn’t be much if any additional flex. I would be more concerned if the top and bottom of the section are cut.
@@nicholasaitken1415 Agree
Actually it compromises nothing. Thanks for playing
As we did in the cabin of the boats at Night you use a low wattage RED blub to light up the cabin so we cab see somewhat outside...As the military does as well to help you see better at night does not overpower ur irris with white light.....
Out of everything that is just plain amazingly awesome and high-tech, what I love most is how clean everything is on fitment and presentation. It is a piece of art, like each piece was specifically designed for this one purpose. Amazing job Zack!
This has been one of my favorite series.
After it's finished I would love to see this traveling around and making appearances on other shows to bring more traffic to your channel. I can definitely see this showing up on MKBHD and Lew Later.
Thoughts? If not grab a huge sponsor and take it to major cities for meet and greets and show it off.
Been following and admiring this series for a while that I actually felt the happiness of completion! For the last 5 minutes I was smiling like an idiot to the screen
Same.
Congrats! What an achievement!! Did not miss any of your videos can’t wait to see it all ready with the full paint and all!
It's amazing seeing how different everything is since it started, I love this series
The drive shaft underneath the centre boxs need to be a little more secure i think by making a tube chassis type of thing around it,just to be safer if the shaft breaks or something
As someone who's in the military that drives humvees in daily basis, it's so weird to see it drive so silently
@@JM-oi9pk my god.. Seriously you compared the first try ever EV by a RUclipsr with freaking Tesla ? Haha
@@azamshukri7741 Tesla Owners will try to brag about anything.
@@JM-oi9pk You're more than welcome to make your own electric Humvee and get it to run quieter as your Tesla. Until then, leave the room so the adults can talk.
@@JM-oi9pk but unlike your tesla, it actually looks cool
@@JM-oi9pk You just said it to brag about your Tesla 😂
For the under dash wiring you should do wax cable lacing like aircraft use. Does sheaves that cover wire some times rub over time and ware a hole in the wires.
The most unique beefy and technically well thought out electrified conversion ever seen on RUclips! I take my hat off to your ingenuity and forward thinking throughout this epic build! 😃👍
11:12
Zack: “I can almost feel the wind through my hair” 🤣
Zack: I am not a smart person
Also Zack: *Proceeds to build a car*
Also Zack: installed an elevator at home
Also Zack: built an electric quad cycle
Zack is our first pick during a zombie apocalypse 💪🏾
@Godkey 3. He used all of his brains to build it
@@G4UL so did Einstein.
I love it.. Being an "off-road" vehicle I wish you'd add some loctite to all of those bolts everywhere.
This was one of the most satisfying videos to watch in this series, yet!.. and not just because of the major milestone but also for all the detail in how those battery boxes are constructed. Impressive. Congrats!
Congrats man! What a year this is going to be 🎉
At long last. I've enjoyed being on this journey with you Jerry!
Been watching this project since day one. The amount of hard work and dedication you put in this really paid off, i am more than happy for your success. Congrats!
Exciting to see this move what a cool build!!
I've been here for learning, but who am I kidding. I have been here to see Zack's excitement once this baby starts rolling. Paid off! MASSIVE MASSIVE RESPECT.
The day He started this project I wasn’t sure how the things will come together, but then I watched every single episode of this project and things were much clear !
As I software engineer I can understand how joyful it’s when you are done with a project and it works, Congratulations Zack
Right on, right on, right on!! 👍 sounds like the gear box takes a while to lubricate itself, but after a few minutes, the oil is thoroughly flowing.
I'm hoping D brand makes printouts of the insides of the batteries to stick on the battery box.
This episode was genuinely worth the wait.... It was AMAZING!!!!!!
Jerry I hope you get a chance to take this beast for some serious off-roading someday! Imagine enjoying nature without diesel pollution in the future, everyone wins 👍
Bravo, there was never a doubt, you can JerryRig anything.
as an engineering student this project is so fascinating and watching your videos for this series for twice or thrice like a kid watching cartoons 😅 and also I can almost feel wind through my hair as the Hummer is started 🔥
“Overkill is a good thing” This is the difference between engineering on the fly and engineering to make a profit. Engineering on the fly is not as financially constrained since it is based off of your cash flow. Let the project take longer and you have more money to spend on the project. Engineering for mass production means every time the design saves money that ends up being money you can spend on more features or more RnD for your next product.
I’ve been here since day one of the series Finally And then also a part of the car
Feels great to see it finally moving, can't compare to what Jerry must've felt since it is his project ☺️
Man, it all coming together is so great, it's been a joy watching this, and it was making it, you can tell.
Your best project so far, and one of the most impressive YT series of the past decade. You rock Zach...
Have been waiting for this day all along and here we are.. so amazing to see this finally come together on its feet(or wheels rather ).. the entire journey has been so absorbing and equally connecting to the viewers.. i'm sure many of us started clapping around on seeing it move for the first time.. Thank You Jerry for this series and making us all part of the experience.
its really awesome, waiting for 6 months just to see this baby move. congratulations jerry. its a great success
lots of love 💖
Awesome job! The whine is extremely annoying though, reminds me of some of my RC cars, in rc it is usually fixed by adjusting PWM settings, not sure if it applies here. My current RC powered by sensored BLDC motor with foc control is completely silent and so is my sur ron ebike, so there must me solution out there, keep up good work!
Awesome Build!.
"If it's worth engineering, it's worth over-engineering!"
I laughed, that after you have put so much time and effort into the project, you still seem surprised and excited that it actually works. Best feeling in the world, that sense of achievement on the first drive of a new project vehicle.
Keep up the good work. ;-)
That's up there with "do it right, do it once".
@@mikes78 Always try to do it once, but it's always done better twice, or three or ...... times. ;-)
this guy made an entire electric truck and companies are struggling even after launching before this guys started working on this project.
I am following JRE, may be just because of this project, but I have to say this series is the best one you can find on the RUclips for any DIY stuff.
respect man!
23:10 if you dont have rubber liner on the metal holes in the hummer Id suggest to add as a precaution even if the rubber liners of the cable are thick
Wow, that's cool. The level of tech know how that's needed for this project is steep. Congrats on finishing it up ; )
Love this series so much. I’m very interested to know what the final front/rear weight balance will be! And how it roughly compares to the original balance. Keep it up Zach!!!
Never missed any episode…it’s been quite a ride… loved every second of it… all the good wishes from India 🇮🇳
Waiting for the launch 🚀
Congratulations! I have been with you since you brought the hummer home and with you as you got the hummer turned into EV!
looking forwards to build progress.
i can almost feel the wind through my hair

Hey zack, i know its still a long way to go before this is anywhere near complete - but is it possible for you to put up a graphic (either in a video, or elsewhere) that shows the breakdown of what you are installing into the hummer and where it goes? like top down view of the hummer with the engine and ESC in the front, ecu somewhere in the middle, 12v system in the passengers seat, batteries in the back, and what ever is going out the back of the batter box etc? maybe if you 'have the spare time...' mark what things you have done etc - just something to help everyone follow along with what is a very complex conversion for most people to 'just know' where everything goes or what is needed?
a series unlike anything else, and to see it succeed was absolutely brilliant! great, great job Zack, thanks for documenting everything so well :)
Idk if it's just me but as watching this I felt so chill like just to the point I almost fell asleep all the sounds of drilling and tapping etc.. and Zack's voice is so calming to top it off. The only thing that kept me awake is how cool the build is and how it's going.
Such a brilliant series Zack! I wait so eagerly for these!! Couple of questions
1. The metal box is so tightly enclosed (including water seal) but the front portion seemingly has a gap? Was this explained somewhere in case I missed?
2. What are your thoughts on that metal box not being easy to tear apart? What is some battery module dies, wouldn't the replacement be super hard?
3. Thanks for mentioning the whining noise. When in your previous video you had it installed, I saw no comments and thought I am the only one hearing the tinnitus like whine. Is it from the inverter?
4. Are there sensors inside battery enclosures that does monitoring for you and show alerts?
Yeah and head didn't use thread tape for the breather valve or other threads which seems a bit odd since he went to such a measure to seal it
@@Encrypt- no need for extra sealing because there is an O-ring that does the sealing.
I'm pretty sure the whining is due to the inverter. Actually the noise itself probably comes from the motor but it's because of the inverter switching. Other electric vehicles definitely make the same noise.
@@wolfgangornig3556 ahhh I see the o ring when he shows the breather at the start just not when screwing it in! Still not sure about the o ring threads or the big hole in the top of the box though
1. Was my exact same question
We've got a roller! "Amazing work" doesn't even come close to describing this. Loved every minute of this series, and I mean what's not to love, been smiling like an idiot seeing it move under its own power. 💖
This has been such an awesome journey, almost felt the first drive joy through the screen. Proud of you Jerry 👏 🇰🇪
*Zach
...Also RTV is what that orange goop was that had it water tight when you started (only orange and black are two different temp ranges of the same stuff).
at 22:12 Zach says bokas. You can tell he is exited lol
