Electric Moped Battery and Spot Welder build

[@ttroy350]

This channel deserves a million subscribers

[@kendingsor]

I like the part where you took a gas moped and then converted it to an electric moped

Thanks for keeping your videos dense, we get to see you make a new tool, fabricate sheet metal, and play with power electronics. I'm excited for the next episode of the Jeremy show, so far the character development has been top notch

[@ironhead65]

8:09 oh wow! Nice use of a machinist jack! Great idea!!

[@TacticalBurritoSystem]

Jeremy: Huh, need a spot welder Me: start looking up aliexpress Jeremy: I made one Why does this dude not have more subscribers, its like engineering ASMR.

[@RobertAdairWorkshop]

The Emo Pad joke is totally under appreciated.

[@Mr49Studebaker]

I really enjoy your channel. I find it impressive just how many things you will tackle.

[@mikebroom1866]

I messed with several spot welders. Finally pulled the trigger on the malectrics. Sooooo glad I did.

[@JacknVictor]

I'm doing a similar project (still gathering parts) but your videos are helping me a lot. I've got a tomos a3 from 1985, and I've virtually planned to do everything you've done to yours (the bikes are basically the same, very minor design differences) and I swear im not copying because I bought my bike about 8 years ago to restore, and about 4 years ago came up with my conversion plans as i decided I didn't want to restore it, more redesign it to my own design. The difference with my bike is it has a linger seat with room underneath for some battery cells in a pack but not enough, so what I'm going to do is cut a long door the length of the tank either on one side or on top, with a hinge so I can make up a full battery pack that will sit neatly inside, and ince the cover is closed it will look pretty much the same shape as it was before. The sad thing is I'll never get to ride it because 3 years ago I lost my leg due to an infection when I got COVID and my other leg is pretty much frigged aswell. But I still want to complete this project, and then maybe if I can raise enough money from its sale, I'm going to build myself an on and off road mobility scooter. I've got a scooter chair at the minute, but it's not much good for me, and I had pretty bad accident in it last week it tipped up on a kerb and I fell out and it landed on top of me. It's no good but it's all I could afford at the time. My buddy is going to help me build both the moped and my scooter, and I'm going to give him my old scooter to use to build his kid an electric go kart. Like I say, it's not any good for me but it will make his kid an amazing nippy little racer. Love your videos. Just found them today. Subscribed.

This is very educational thank you absolutely love this good to watch this man is highly skilled and experienced I appreciate your nolege

[@lumotroph]

This is incredible! What an array of awesome things you’re doing 😊building a spot welder unexpectedly in the middle of a video! No clickbait!!! 😅

[@Anders0nic]

I continue to watch and learn!

[@billbaggins]

I knew the joke was coming but I still laughed 🤣 Making good progress mate👍 Can't say that your channel has no variety 😁

[@robertlong9029]

Remember that even the disrespectful comments help you make money, so when some foolish person tries to insult you that it’s just money in the bank. Hater’s are going to hate. Lol

[@haydenc2742]

Oh...final paint...should SO be WWII olive drab with subdued star and all that Very cool build! Keep em coming!!!!

[@brendonfriesen8327]

Great job of the battery case. Fitting with the general aesthetics of the era/fabrication style while not trying to pretend to be something it’s not(gas powered).

[@yeagerxp]

Excellent work 👍👍👍. Thank you for sharing. Be safe 🇨🇦

[@minskmade]

niiiiiice....great battery box build...im in hte middle of collecting parts to convert a 1979 vespa p200e. to electric...awesome video as usual sir...thank you

[@kids832]

I have these same modules. I have two, put them in series and bought a 72v motor

[@JeremyMakesThings]

They’re a good deal. I bought 20 more for my Jeep.

[@kids832]

@@JeremyMakesThings definitely interested in that build. A few friends and I were trying to convert a 1980 jaguar. We found that doing a Lexus Electric motor off of their hybrid is the easiest and cheapest way with about 300hp. Shaped exactly like a traditional transmission

[@JeremyMakesThings]

@kids832 I think Damien McGuire has a bunch of videos on working with those transmissions if you haven’t seen them.

[@Corn-ped]

heck yeah! this is great! how did I miss this. Keep it up! I wanna see a top speed run!

[@Lonwolf4019]

I have been awaiting this upload I really liked part one and couldn’t wait for this video to see how this was coming along it’s awesome

[@robertschmidt6383]

My god your a genius.

[@stewartfrye]

WOW! Talk about content, 10

[@zachaliles]

Being an EmoPed the exhaust is gonna go "WHERE ARE YOUUUUUUU"

[@ctrlaltdude]

I was hoping you were going to put the batteries in the gas tank. I have a similar project on hold right now because I'm not sure if cutting open the gas tank will cause structural damage to the frame. So would have been nice to see you do that... :D Oh well now I'll have to try it myself.

[@JeremyMakesThings]

The tank is definitely structural on this one. I think with proper reinforcement it could be done though.

[@zooobidooo]

Brillant job !!!!!!!!

[@Dreddip]

I thought you had a kWeld for some reason 🤔 fantastic job!

[@googleuser3110]

[@choppergirl]

I've got a Baja Heat frame I'm thinking of doing this with, but something like a moped frame like from a Honda C70 / C90 like you did is another option. Three wheeled trikes also look interesting. Still mulling it over what frame I want to use. I see a bunch of 21700s in that industrial battery. Where did you get it off of, ebay? I bought a ton of them new to use on my Quadcopters, but not that many. Most people use a spot welder on these, but I actually played it dangerous and soldered my leads to the batteries to combine them. I store mine in the lettuce crisper tray in my refrigerator at storage voltage to keep them degrading... it's been 3 years now and so far it has worked. Just drill holes in your bin in case something spills and fills with water so as not to ruin yourbatteries. I hammered some license plate holders just yesterday... for my motorbikes. I've hammer build a battery box for my Honda Rebel, and built Lion packs, but not one for the other at the same time... so... interesting. The downside is you'll have to make a custom battery for this any time you need to replace it, which is probably a PITA compared to buying something off the shelf drop in.

[@calvinboykin4777]

This electric moped conversion is sooooo cool!! You said you were going to put it on the back burner for awhile. Are you considering going back to the electric jeep conversion now?…… I hope!

[@JeremyMakesThings]

I’ve got a couple projects I want to knock out, one is tangentially related to the Jeep (as was this one), and then I want to go full speed on getting the body of the Jeep wrapped up…and then on to the conversion. I’ve been do a little bit of behind scenes work on it along the way too, and I’ve been amassing parts that need to go on it.

[@normanwray1341]

Hello Sir, you know what you are doing 😮😅 thanks

[@joell439]

Fabulous! 👍👍😎👍👍

[@georgeevans9190]

Binky Rules!!

[@blahblahblahblah2933]

Nice build, but that was some harsh seasonal reality at the end.

[@StraightLineCycles]

If ya can't fix it with a hammer, then you have an electrical issue. 😉

[@patricktyra7316]

watching you weld the bracket over the gas cap i was thinking how in hell is gonna get fuel in it , then i woke up

[@FishyBoi1337]

Crazy how further north, winter is when you CAN'T get things done. Down south, Winter is about the only time I can do anything because it isn't mosquitoes and heat stroke° outside! (that's an imperial measurement btw, don't know the imperial conversion)

[@scotttryan]

Surprising how easy it was to get into that battery. I guess the difference between industrial and commercial products. Do you build your own skiis too? Those ones in the background look they might be a diy pair.

[@ferrumignis]

Will the bluetooth work now you've put the BMS in a beautifully fabricated faraday cage?

[@JeremyMakesThings]

Yes. Still works fine

[@rossnolan2883]

😊😊😊😊😊😊😊

[@MurlWatne-io2bo]

I think NASA might be interested you.

[@juliediazin]

I feel you shouldn't put so many screws on the battery box cover, considering the large number of cells in there, if you had to remove the battery pack in a jiffy, that is way too many screws to remove.

[@jdmccorful]

Couple things to say for your battery endevors. A very good reference for Li battery builds and knowledge is " DIY Lithium Batteries, How to build your own battery packs" by Micah Toll and published by him. Can't go wtong with this tome, helped me tremendously when I was exploring the subject. Second, would suggest you read article in todays, (11/11/2023) saturdays/sundays edition of the Wall Street Journal. I believe you will find the EV article in the business section. It'll give you some food for thought while you consider your jeep build. Elsewise , really enjoyed the work done in your video this week. Thanks for the time you put in for us "nerds". Please take care of your hands, they are as important as your tools.

[@JeremyMakesThings]

Cool. I found an article about needing more utility poles. It’s an interesting consequence, but the bigger issue is really the fact that we haven’t been investing in our electrical infrastructure for so long. I ordered the book too. Should be a good reference to check my work against.

[@jdmccorful]

@@JeremyMakesThings you will probably find it very interesting, being a curious fellow.😉

[@BrianBoniMakes]

What do the pedals do?

[@JeremyMakesThings]

Nothing right now because I don’t have a pedal chain on it yet. But like the Mitch Hedberg joke about escalators, I moped can never break down, it can only become a bicycle.

[@BrianBoniMakes]

@@JeremyMakesThings Technically it's no longer a moped, make sure you aren't required to have a license. You have good metal working skills. I liked watching that.

[@VentureWelding]

Is it REALLY cost effective using smaller cells like this? 🤔 Another question, is once you add up the cost to convert it, plus your time in labor (however you'd value that), at what point does this bike start paying for itself once you figure the two gallons of gas per tank you're saving?

[@spongeimperium126]

Ride video?

[@nickhenscheid369]

Does your battery box need ventilation of any sort?

[@JeremyMakesThings]

Not unless things go very, very badly.

[@striknein]

How's the center of gravity on that hog?

[@JeremyMakesThings]

It certainly higher than it was, we’ll see how it handles once the snow melts

[@CALDues]

😂HOG!😂

[@ramone79]

Mayby i missed it but what gearing and chain are you using ? DONT put baby in a corner ( Like Patrick Swayze would say ). I got parts for a Puch Maxi kl and a vevor 72 volt 3000 watt my1020 ( controller 72 volts 65 amps )

[@JeremyMakesThings]

its a 9 tooth minarelli sprocket on the motor (I showed how I made it fit in the first video) and a 60 tooth rear (the builder one treats sells). Normal moped chain.

[@nigelpickett2471]

What about cooling? Especially while charging?

[@JeremyMakesThings]

It’s not really needed. The temperature rise when charging was pretty minimal as demonstrated. In the box it will be a little bit more, but not significantly. I won’t really be pushing this battery very hard, so air cooling should be fine.

[@jdmccorful]

@@JeremyMakesThings the charger is where you might consider "cooling".

[@sparkfishes]

Not everyone enjoying your videos are in the USA so, what was the yellow tape you placed on the batteries please ? I have never seen any thing like it in the UH

[@JeremyMakesThings]

Kapton tape or polyimide tape

[@normanwray1341]

Used flox wire😅

[@be007]

tjeez, ending with a clifhanger, me not like ! cheers ben.

[@twotone3070]

I had visions of it completely black and instead of a horn it just repeats "Yeah, whatever" . I mean, that would be an emo ped, right?
