Only seeing this in April 2021, but I enjoy that you modify and experiment and then put it out there for newbies like me...I have learned alot from this vid and thank you for you work!!!
My pleasure.
jerry is absolutely right about thickening the phase wires to let more current flow BUT not until you get a controller that will allow for that extra current. controller first. phase second
If my controller is 48v with 30A current. Will I get more speed if I upgrade the phase wires?
@@lincolntay5246 it depents on you BMS if you got an 48v 15 ah pack it comes usually with 40-50A BMS you can go then for an 45-50A controller
@@salviaaable man where do I learn all these terms haha I’m new to this stuff
@@echospace7347 just keep on watching videos about E mobility here on YT they are plenty of channels to learn from, EV customs for example
Thanks for the tips nice one
So in resume; if I wanna go from 48v to 72v I would need.... a 72v battery, a controller that can deal with that voltage (or upgrading the capacitators/mosfets of the one I have), a thicker phase cable (like you are doing), and... Telling to the display that the wheel size is smaller than actually is, so it sends more voltage, correct?
That's a lot of work! It's incredible you managed to do it.
Good job. I replaced with pure silver 14ga wire and PTFE shrink covering. 72 v. Much more power!!
Great !! Power through efficiency :D
Hello , I'm attempting to follow your lead and attempt the same thing on my das-kit 500w . The motor and controller that came stock does 38km, just throttle,and it does this with my roommate on the back. That's 400lbs. I was going to get a different motor but I'm going to try your 14guage trick first
Jerry, it's really simple nowadays to build a battery, even without soldering, & they have kits that you just push the batteries into & bolt all together. Your definitely a smart enough dude to take it on, & you'd get 35-70 miles on 48v/20ah battery, depending on the weight of bike & passenger together
Can I build an 108v some odd battery? I want to know what my limitations are on that end. I ride a 48v 500w ebike, I know I'd have to change the controller units. And probably a motor upgrade if I want that balls to the wall.
@@johnnyz.438 a house fire once you discover 1 cell is damaged from diy gone wrong and no "real" proper method of testing anything. enjoy.
Hey man, sick job on the phase upgrades!
You should get your hands on some nice thick copper wire and re wind your motor too, you can get much better power through them with a little more copper density, also don't forget to replace a plastic gear with a metal one on your planetary clutch, it'll stop you from shredding your gears long term ;)
Your phase wire upgrade means your windings will get introduced to more current and voltage (efficiency boost) So it makes sense that the windings could heat up more now than previously. (If you're keeping the power low its not much of an issue, but you seem to be the type that would like to juice things a little harder, like myself)
@On A Mission umm, sure thing mate.
Perhaps your understanding of the subject is just lacking.
Punctuation, grammar and proper sentence structure, I don’t really see where I went wrong 🤷🏻♂️
@Mission Gameliel Im Aussie, "Sick" means good.
As in;
"Fuckin' Heaps Sick Cunt"
Thanks mate i.ll try that get some copper wire and start winding.
@GameliEL Auceps
Sick (slang) = cool/awesome/impressive
@GameliEL Auceps I mean, if you live under a rock 🤣
Ever heard of context.
Sick has been used in many ways, including the way I used it, for over 20 years, perhaps your intelligence or rather knowledge of general communication techniques is lacking. Guess your "common sense" just ain't up to snuff mate.
Great work
Informative video explaining your performance concept .
Glad you liked it
You have to upgrade your controller to use this 80v battery. My motor and controller both broke costing me hundreds because controller and motor couldn’t handle the battery power 😂
It was fun for awhile, I felt the power and it worked but ultimately ended up burning up everytjingn
That new G062 1000w hub motor seems perfect for this. I can't find any information on it. I watched this video years ago when I first got into ebikes. Now I have 3. I'm going to put a 3000w Sabaton controller on mine. I build batteries so I have 2 100 amp 48 volt 35 AH that I can run in series together for 90v 100a.
Very very interesting, Thanks
Glad you enjoyed it
Thank you brother 🙏
My pleasure
Is a DC brushless controller the same as a brushless hub motor will it work if it's the same watts and volt 1000 brushless motor hub kit
Excellent!
Ive been looking at all videos about rewiring ebike hub motors &cant find 1 which shows exactly where each phase wire attaches inside the hub. Obviously like for like reattachment as per hall sensor wiring but my problem is that i had an axle spinout on my Dapu M155, after which the motor has not worked. the yellow phase wire is not attached....display shows o.o speed and PAS 0. the lights also wont switch on, after 10 mins the display shows 33 the switches off..any ideas apreceated
Do the 82v greenworks professional batteries work?
Snapper is 82v too
Yes
Best video ever
Fascinating. I have a question. Does replacing the phase wires with thicker ones actually increase your motor's power or speed? Have you noticed a significant difference in performance?
Higher voltage = Higher speed. Once upgraded to Higher voltage system, the original wires have to be replaced otherwise they'll burn out.
Voltage doesn't raise the heat. Heat is only influenced by amperes. But a too high gearing (winding) can be inefficient at lower speeds.
@@emilen2 he prolly left the amps at the same level after going up in voltage, when he should have lowered it since a higher voltage needs less amps to achieve the same outcome. Idk what his wires were rated for, so who really knows why he did that is just him
thank you!
Amazing
On a 750wat ordinary motor how many magnets has 750wat hub motor need tp no for display references thanks good job on motor
Thank you.
You're welcome!
Can this be done with a 250w yose power motor?
So much torque that he's slipping the rim liner
This might be a dumb question but could a 72v controller work with a 48v battery plus Hub motor?
So if you are going to set up the hub motor to allow more current flow, you need more current flow. You can do a shunt mod on your controller. TH-cam will show you. Also, prob need to add some heat sinks to hub and maybe some ferrofluid to magnets.
What is your top speed with 80V? What size amperage controller are you using? Interesting build.
35- 40mph, 50-60a controller is good.
@@JerryMinne do u know where I can get a 1,000w gear hub motor?
@@dimitrimcintosh8858 aliexpress
@@dimitrimcintosh8858 I bout a 1500w and 52v battery on Amazon. I hit 40 on a fresh charge lol
@@JerryMinne dumb question here, but how do some people that have a 72v battery get their bike going upwards of 80, and one even close to 90 miles per hour? Obviously they have different motors but my question is what exactly is required to go fast? Is it all about the gearing? Like people on surrons have 72v batteries and a BAC4000 or BAC8000 controller but like in the end, what is required to reach high speeds? A beefy battery, a high amp controller, and a way to keep your motor cool? Do some motors just max out at a certain internal rpm? Or is it the gearing of the motor that holds it back? I have heard some on TH-cam talk about overvolting motors and that “in theory” an electric motor has no limit besides it burning up. If this is really true I’m wondering why people aren’t going 50mph on cheap motors. Is it not enough torque and wind resistance so they reach terminal velocity at a much lower speed? Or does it all come down to voltage and the controller?
Im sorry to say that just by using a thicker phase wires one can never ever double the motor power. Never. To be able to have a more powerful motor system you need to upgrade the controller with a more powerful one so it allows more current to flow towards the motor otherwise your thicker wires wouldnt do you any good. In some cases some smarter controllers can be specifically programmed to deliver more current to the motor resulting an increase in power but judging by the looks of your controller I very much doubt that is of that type.
Hi great video and info
I got 72v 20ah with 50amp bms and 1500w motor witch I getting good performance of the motor so now if I change the motor to 3000w witch is have same winding will I get better performance or nothing will change any advice pls
3000w should be double the size of 1500w motor. If they are the same outside, more likely they are the same motor.
@@JerryMinne no friend motor is same size abit beafier but a lot heavier
Did you try this?
where you live brother? i love ridin in the snow too. i want to do this upgrade but afraid il lose whatever range i still have on a 3 year old battery. good video thanks man
How can i start an hub motor with hout display and conrtoler only battary ?
I have an old prodeco tech 750 watt motor hub,, can I swap my controller to a 72 volt battery to get more power without frying the motor?? Any help would be appreciated it!! Thanks,
Yes. Higher voltage equal Higher speed.
Nice👍👍👍
Interesting thread pattern on your tyres. What make and specifications are they or any chance of a link to them. ????
If my controller is 48v with 30A current. Will I get more speed if I upgrade the phase wires?
No. Higher voltage equal higher speed.
Hello there.
Only 1 magnet is visible on the cover at 07:00.
is this not a problem for the bike to work properly?
I've got a ton of 60v snapper batteries
What kit would work from Amazon /eBay that would work?
Thanks!
The most 48v 52v ebike kit will work with 60v batteries.
hello sir, i got a bafang 48v500w motor, right now i am using 48v/25A+1A controller and 52v25ah battery, top speed almost 50kmh , but i would like to increase the torque of the motor, what should i do ? thanks. good video
The only to increase torque is to get bigger motor. Higher voltage doesn't increase any torque.
@@JerryMinne thanks for your reply， but will any thing changes after i change to a 48v38a controller ？
It won't have much different. Even though the motor may take more than 25a at peak, but that is several seconds things.
CHANGE to a geared hub motor if you want more torque, thats the only way to get more torque, as its a direct motor to hub assembly, also upgrade to flat pack lithium cells that provide 40 or 60amps continuous. my pack can push 200amps but my controller only needs 20 amps and it pushes that uphill max and i have no voltage sag. cylindical cells suck thats why most EV vehicles use flat packs, actually my battery is built with those cells worth every penny. i have 36v 2.5kw 70ah per cell, max speed flat throttle only on 20in wheels is 15mph the best part is on hills i maintain 12mph uphill at 20amps.
I burn my hub motors going up long mountain roads. They just bog down and overheat, especially in the summer sun.
Increasing power would only make it worse. Need more torque AND to increase cooling!
Probably need lower gearing for more torque.
How did your motor hold up with 2 X the power?
Hi sir and happy New year!!🙏
I just buy a YYK 50a controller and have 12 awg phase wires
My motor is 2000w but i was working with 35a controller till now and the thickness of phase wires is up-down as yours!
My question is.....🤔
Can i put together the stock phase wires with 3 more wires 14 awg and conect them (3 stock+3 14 awg) 6 motors phase wires to Controller 3 thick phase wires.??
I will open new hole from the other side of the motor!
The voltage is 72v (if it matters)
Thanks!🙏
Normally there's no enough room for extra wires.
@@JerryMinne i will drill the motor from the other side!!
Good luck on that.
Hello sir: i have the rad rover (rhino) 5 (250 w). i want to make it go faster. Do you have any suggestion what i can do to make it go faster ?
You need change speed controller to match higher voltage.
@@JerryMinne okay. So i only need to change the speed controller ?
Upgrade to 72v speed controller then you can use pretty much any brand high voltage power tools batteries.
Would there be a difference of only using a 52v battery?
Yes. If you ride off road, you can feel the cable will heat up so quick.
Bigger wires mean more current, more toque, more capable to ride up hills, off road...
A link to where you bought your 80v battery please ?

5:15 what is magnet size ? (L-W-T ?)
Nominal: 500w | Peak: 750w
What was the top speed before and after the modification?
With 48v battery, the bafang 750w motor speed is 25mph, 80v battery can get 40mph.

Just follow this video you can double the power of your ebike.
I don't think that I live to far away from you...??.. I live here in the area of San Diego... Can you help me out here and bring my Hub motor up and alive with your expertise..??.. Please let me know if you are able enough to do so for this weekend..??.. Thank you..
did you disconnect the speed sensor in hub motor?
No. The hall sensors are required for the most ebike controller.
@@JerryMinne would the hall sensors work out the voltage without controller . ie circuit boards inside hub?
Hall sensor requires 5v voltage which provides by the ebike controller.
Hello! Your videos are addicting lol. Are you interested in putting a kit together for resale? I currently have a 56v 2.5 AH but plan on getting the 7.5 AH here soon with another power tool. The kit would include the upgraded hub and batter connector on the other video you have for ego? Just curious
@@cmase1000 Nah
One battery in. One battery out. Choose a route that isn't predominantly downhill going in. 😁
I dont understand .. I feel something is wrong .. how can I increase the voltage to 80v while it is 48 basicly??? It will damage the motor and the controller.
Now if the voltage still 48v , so what cat the thick wires do !!!!
wish you showed disconnecting the wires. Cool video though. Thx
Using torch or high power soldering gun.
I got 36 volt Junk bike, can I test rear hub . By direct with a . 36 volt battery. From stihl chainsaw. 4 hour battery. 36 volt😮
Yes. Make sure secure the battery connection.
What amp controller do you use?
55a
Do you have to solder the wire?
Yes for better connections
@@JerryMinne thank you for the response.
So you don’t use the julet pin connector anymore? Just directly connect new thicker wires to controller wires?
Do you think I will improve performance on my fat tire bike with just this upgrade?
I have a 1200 watt motor and 52v battery. Thank you in advance!
Also do you know how to derestrict or take off the speed limiter so I can have a higher top speed?
hi, my english is pretty bad, i just replace the 3 motor cables and voila? or do you add an 80v battery? thanks
To get advantage of 80v battery you have to replace 3 phase wires.
you need to add the 80v battery
@@hydralizk6631 if you have a newer e-bike you could also add 1- 52 volt (sold as 48 volt) battery in series which would be a 96 volt battery as the higher powered e-bike come with a 48 volt battery

Powerful motor but the range on 1 battery is very poor, not worth the time and trouble for these upgrades.

Higher voltage equal Higher speed. But common controller can only handle 96v or less.
So your not going to get more "power" essentially, but it will cut out some restrictions... Small wires will cause a restriction that creates heat which is the enemy. Think of a hairspray cap with that little hole... Run faucet full blast but only a small drip coming out. Make the small hole bigger you still have the same amount coming in but it lets all current flow easily... Hope this makes since
What batteries are that
Greenworks 80v battery
Thanks. God bless you. Im a christian i hope you too 🙏
Adding a second battery doubles the distance not the power.
Increase the power and decrease the range... whoop.

Probably need lower gearing for more torque.
I'm I'm in Florida I put fan blades work by my motor just like about 4 inches wide to go around they took the lot
So if you change the battery to a 80 watt how much is an 80 watt battery? And don't you need a new controller if you do that? And I really like those tires they look like on off-road tires and I've not been able to find any where did you get those tires? I want tires like that and it won't make so much speaking noise like mine I have a 2020 ecotric Hammer bike I have 600 miles on it. Being disabled with one leg this bicycle saved my freaking life saved my life I have no other way to transport myself
6ah 80v battery is about $140. You need controller that supports 72v system.

That's the 500w motor that's set to natively deliver 750w. You've been scammed through false advertising.
I'm probably scammed too although it has engraved 48v 1000w on the hub but it's way smaller(it looks like the same size as in this video) than a regular rim 26" 1000w 48v that I had in the past

sorry jerry but there is one thing wrong with your theory. it is the controller that dictates how much power a hub motor recieves. not the thickness of the wire. people, this is alot of work for nothing
Yes and no. The controller controls the speed, of course, but not the way you think. As I said the controller controls speed not the current. The controller has limitation on current but actually control it. For example, when motor has heavy load like climbing hill, you give full throttle, so the controller has maximum output, but the motor try to drink more current. in that situation, if you have thin wires, the wires burn out, if you replaced thicker wires but has small controller, the controller burn out.
Still don't know how you gotvthose wires in
