Ladies and gentlemen this is Master builder !!!!
Thank you, I also got my first customer 🤩🤩
@@E-bikeguyNice video. I have an Aventon Aventure 2 ebike, the throttle is factory set for 20 mph. Is it possible for me to increase my throttle speed?
@rbcapbustditto thank you,, well the throttle speed is set by the controller software, and shunt mod will get you there faster.
Man this is what I was looking for nice one from England all this ebike stuff is excellent
Thank you, it's definitely worth the mod.
Same big up grimsby aha
This Gentleman is a Master of all facets related to the E-bike.🙌🏿🤙🏿👑☝🏿
Thank you!
@@E-bikeguy Blessings! 👑
ok, excellent point. I did the same last week. This is electronic knowledge.
whatup
way to make it easy to listen & learn.
appreci8 ya
Awsome info I’m a fellow rider also nami guy!😂❤
Cool hot rod mod! I feel the need for speed⚡
Lol it was good for what it was after I did the mod you will definitely feel the difference, but it has nothing on the new controller lol
@@E-bikeguy do you know anything about the adjustable POT?
Not really.
Thanks for the content, man!
No problem
When I was doing my electronics degree back in the 80's we used to get electrolytic caps, charge them, and then throw them to people and yell "Catch!" LOL Man I got so many of my fellow students. The brainiacs were the most effected.
🤣🤣🤣🤣🤣 wow!
Hi mate av just put a build together the lcd screen works but no throttle the kit was for 52v battery 2000watt motor but av put a 60v battry on and the controller is for 48v could this be the problem why throttle aint working?
Thanks again I have some controllers from Violimart I will be looking at them
No problem 👍 yes it's a cheap way to get the most out of your controller
I got a question I got a 72 volt 3000watt kit it comes with a yellow brick connector for the motor and controller and battery and idk if I should use that bc everyone says that’s how fires start. I was told to solder the wires together instead or use bullet connectors what do you think?
Anyome able to tell me the answer to this , i need a 3k watt controller for my ebike do they all have the same wires for hall sensors?
My 45 Amp controller can take 80+ volts.
Do you think it has a shunt like that I could mod ? ?
It's maybe 5 years old, didn't come with any displays. Runs my diy disability scooter up to 37 mph at 80 volts using a 350 watt 36 volt direct drive 16" hub wheel
This is Great, I want to try it on my Swagtron EB-8 has a 350w motor stock. I swapped it for a Super Dolphin 500w rim / motor
Heck yeah 👊🏿 it works 💪🏿
Nice , I have a Q20 Pro AWD with 52 volt dual batteries and dual motors , would that work with this bike also ??
Thank you for the video
No problem 😊
How much you charge if we send you the controller?
Im tempted to try this on my 13a controller the size of a pack of cigarettes but I would have to calculate the shunt resistance i need to make it 20a max, not 40a, because my BMS is 15a with a 30a fuse.
I would go into the upgrade death spiral because i need a stronger BMS to supply the shunt mod controller.
Lately every repair/upgrade i do causes something else to break. Lol
Oh wow, this controller was great after I did the mod but no where near the power of the new controller we just installed
@@E-bikeguy, yes, your controller is 15 Mosfet so it seems ready for amps. I think mine are 6-9 mosfets in all my controllers. My Votol is rated at 32a but you can set it for 45a or higher if you want.
Oh ok yes I know for the most part that all controllers are not the same I guess got lucky that this controller can take more abuse than others
I have a 52volt controler and battery.If I do the procedure do I need a higher voltage battery or will I pull more amps just by doing the Shunt?This controler I have is 22Amps
Yes it will pull more amps when you do the shunt mod
Thanks
Shunt mod, cool man! I would also tell people to discharge the caps with a flathead screwdriver first before messing around too much inside the controller housing. I recently opened a tiny 48V controller to diagnose it and when I discharged the capacitors it let out a seriously massive spark, that wouldn't be fun to touch 👍
Thanks bro you made a good point with the capacitors, for some reason I touched the back by accident too and didn't even think about touching the battery wires together to discharged them , they do give out a loud spark lol even when you connect battery with anti spark xt90 still spark, I know on a 72v battery .
Great advice..
Thanks! That's very nice to hear, I didn't know it was possible to discharge them.
I remember a capacitor from an old camera once punched a hole in my finger with a flash.
@@Bergwacht lol me too I disassembled a disposable camera and I messed around and touched the ends of the capacitor and boy it gave me one hell of a shock, it blew my mind that 2 AA batteries and one capacitor can generate that much juice 😅
@@E-bikeguy Awesome brother, keep it up! 🍻
Thank you
Anytime
The best Controller for that shunt is 35+2amp on 52v17.5 battery and 35amp fuse use 30amp it blows it does improve torgue power slightly but its good upgrade. If you have 2000 wat bike 45amp lcd sw900 set at 100 speed 52mph you can actually do a shunt on a 45amp controller and definitely get more power but up grade battery it draws a load of amps 72volt battery or I uased green wick drill battery with built in BMS 5v7amp 12batterys so if one goes fa it's a case of putting one battery in instead of buying full battery it works out much more cheaper
You're right as my friend is learning that the hard way lol
What do you mean learning the hard way
@Colin White he shut mod the controller battery too weak
@@E-bikeguy on 52v17.5 it works quite well are you sergest g 72volt battery that controller is for 1500wat and 200wat
@@colinwhite144 just noticed your comment and I done a ebike conversion I run a 52v 19.6ah battery with 48v 1000w controller and 48v 1000w motor, Amy suggestions on what controller to use or what to try to gain abit more torque please
Bro i have a question i have a ebike really nice its 1000w i have a unrestricted display so my battery is a 48v 15ah how much amps i need to do 40 to 45 mph ??? Easy and efficient please help bro
Hi does it give you more low-end torque, I want to kick up some dirt on my moped-style bike but the throttle lags, it's a fast bike top end of 40mph but has a throttle deadzone.
Definitely help in low end torque

Hi , great video btw ! I have a new fat ebike chinese yolin .1000w bafang motor with dual battery 48v 22 amp each ..it stuck at 29 mph , and i dont know what controller i have its under the seat , should i go for 52 volt battery ? or try to trick the controller? i dont have money for new battery and mine are still new ..
Be better off to preform a sunt mod
You know cheaper ebikes that have the controller made into the battery mount. Is there a way to modify it's controller?
That's a good question
Well if you ever find out let me know
New sub 👍🏼
Thank you very much this means alot to me and thank you from becoming apart of my community 😊
Trying to get more speed out a rattan bike any suggestions?
Well you can see if your controller has shunts you can mod them for more power
Im still scared of them batteries. Thanks for the episode. Great heads up here.
No problem 😊
Excellent video. Doing a shunt mod on a 25A controller how many amps will I increase?
Thank you 💯 I'll say about 50amps after the shunt mod
Can you wirer a moped throttle to a 1500 motor and 48 v battery
As long as it us electronically able

Well I got it of Amazon it did say for electric bike and mopeds it just the adapter that wrong
@@kelvinmarland6572 email me at theebikeguy08@gmail.com send pics there
I have no idea what im doing, figured id ask, how would you recommend upgrading a freego f2 pro for more torque? Im a bit of a hazard during takeoff from lights in traffic.
Under the "battery" section of their bike specs it claims to be 48 volts, 22.5 amp hours, 1080 watt hours. I assume the battery is where the watt hour measurements come from. So the speed controller would be where the amp hour measurement comes from?
The hub motor says 1400 watt peak, uncertain of its nominal rating.
What would you recommend doing for my desired purpose? And what should i be concerned about in terms of "hardware clash"?
Ok I'll definitely get back with you tonight on this
bike has a design flaw. due to the batter being on the bottom like that the stones kicked up by the wheel will hit the batters. and if someone pulls out on you and your crash and your forks go in. your wheel will smash right into the battery pack.
its better to put the controller on the bottom
No worries it's protected
hey thank you for all your help ,, i got an avantrek ebike for my nephew, i'm trying to remove the speed limiter, but don't know what's what... there's two black waterproof connectors, one thicker than the other... maybe you could help, THANKS
I'll have to look up the specs on that ebike.
Is this safe thow, or could i risk blowing up my controller.
Well it's both it really depends on the controller
creste doar demarajul nu si viteza finala, top speed nu creste doar demarajul, vrei putere mai mare cumperi alt controller da demarajul va creste considerabil am facut si eu si e belea, poti pune doua fire cu intrerupator si ai power din intrerupator.
Does the “more power” include torque and speed? Mine is a 1500w and I usually top it at 33-35 how fast do you think it will go if I shunt my controller?
Yes you will feel it, 3mph more and about 30% more in torque
Good helpful video! im looking to modify an old mobility scooter i got, would a e-biker/scooter controller work on it? its a 24v 1000w system, i might try 36v 1000w, you think that would improve anything? yes im very new to this stuff but id like to learn more about it
24v to 36v will improve the acceleration and speed, as long as you're controller can handle the extra voltage
@@E-bikeguy thanks for the quick answer i gave you a sub, ill definitely have an e bike some day too
Will that trick work on any controller
Pretty much it will
Hello Ebike guy . I am building an 8000 watt 72volts battery and would like a detailed schematic drawing of yours to emulate. Thanks in advance.
Hey bro question I’m getting a lot of voltage sag I have the same display what do you recommend I keep my throttle power at ?
I would say power level 3 till you get a battery to handle the current but long as the bms is not going into protection mode, but if you battery is at a 100% and you have a voltage sag then might be a problem with the battery's capacity
Hello I have a v20 fatbike in the netherlands we have a rule that it only go 5kmh with the gastrottle on the steer, but mine go 10kmh when you don’t peddle do you know if I can program that or something when I find that solution many people will be happy here becouse you get a fine of €290, when they test it and see it go on the trottle 10kmh and not 5kmh..
Oh man, I really don't know, I see that the laws are really strict over there I'll look into it tho
@@E-bikeguy yes bro that will be awesome if we fix something with that!

Hi can ask something i have a ouxi bike v8 2.0
When i pedal the bike the electric support don t start helping pedaling what could be default
It could be, sometimes you have to go in your display settings and activate the PAS
I will pay an electric guy for shunt mod thursday but most people told me it only increase acceleration not top speed .. i have a 1000w bafang motor and dual battery 48v 22 amp each..i go 28 mph 46 km/h..my controller is 48v ,maximum current 26+1 Amp … will i gain only torque?? is it worth the 100$ canadian he will charge me 😅… Thx again in advance 👌
like the intro and music as well as picture overlay! watching your video made me notice my controller had 100v on those things. I currently have a 52v battery, does this mean if I bought another battery and wired them in series the controller could take it?
Yes it will at full charge my battery is at 67v and the caps is at 63v when I connect the battery to the controller I thought I was going to hear a pop but nothing happened so we turned it on and off we went lol
@@E-bikeguy i ordered the 5000w kit, but ive got a 2000kw kit with a small triangle, might be worth doubling up the batteries and see what happens. if it doesn't work just send battery back.
Ok keep me posted
@@hank_Reardon , if you are saying you bought a 14s Li-ion pack (52v) and want to buy another to put in series 28s, 104v nominal, 118v fully charged, then you will definitely fry everything, the controller, the display, and accessories that are wired off battery power.
63v caps are for 48v nominal.
80v caps aee for 60v nominal.
100v caps are for 72v nominal.
You can get away with 63v capacitor for a 60v Li-ion (67v peak charge) if you are lucky, eventually it will pop if the charger is left connected after the light turns green (as it should be occasionally to balance the cells).
The other big problem is charging them, you will need to plug in two 18s li-ion chargers (or charge one then the other, taking twice as long).
If you bought a kit with a controller, display, (dc/dc converter optional), you need to see what the supported voltage is. Many controllers and displays allow you to select 48v/60v/72v but if you plug in 117v, you will need a new display and controller.
So if you didn’t get what you ordered you will be better off using the return policy (unless you need to pay shipping to China) and get what you want, 5000w motor, 72200 (72v controller), and 72v battery (or two side-by-side connected in parallel not in series). Even with that you might sill need to open then and upgrade them from 60a to 100a each.
If you use just one battery you see what EbikeLife had to do to make it capable of bursts of 200a. The Chinese assembles the cells wrong so he had to bridge over the single strip series connectors because they are only good for 30a, at 60a they were getting hot, at 100a they were smoldering, and 200a they burn in half.

Thanks for info, I'll hold off on that then.
@IMHO
Thanks for info, I'll hold off on that then.
What if I buy 96v controller? Think 2000w can handle that voltage if I put statorade in the hub to keep it from overheating?
Got any info for the phantom sit scooters with the basket on back..as far as speed unlocking??..thanks
I'll check on it
Thanks man🫡
@@Bakwod no problem at all 💯
16s pack fully charged? thats great haha thats 67.2v fully charged so i bought some 470uf 100v capacitors just incase for my 18s battery pack :D
Yes it did great for a substitute controller I don't how much power it did before the mod but you definitely can fell the difference, it be fully charged too
I just bought a juiced bike ripcurrent and it has a 25 amp controller. Would it be safe to do this mod? I don't want to fry it because it takes a special controller and I don't think they're in stock. I know it will void the warranty but that's not a big deal to me as I can do the repairs but it's getting the parts. You can't just use any controller because of the torque sensor they use on juiced bikes. I have a phaserunner controller but it's not compatible with the torque sensor I don't think. I'm still doing research. I sent grin tech an email but haven't got a response yet. Thanks for any help you can give me.
Yes the sunt mod will help definitely in power and you would fry it. When you open the controller up make sure you see the sunts should be located in the back of the controller. And just solder them together but if you can locate them. Then the mod might be the best solution. But most low end controllers or mid range should them. You will be 50 amps then
by a 20ccash step up inverter dc to dc all u need is one that god up to 60 volts if u only have a 36volter u can put it on 50or 48or 46volt dc from 36 an it will boost yr speed so much look vides up of boost inverters
Will getting a bigger controller give you more speed? Or do I need to get a higher voltage battery such as 52 or 60 or even 72?
Yes, getting a controller will give you more speed and power but only if you battery can handle it
@E-bikeguy 48v battery handle a 52 amp controller &1000w motor? Thank you for your reply
@@JHOFF111 a sabvoton 7245 will be great for your application
@E-bikeguy I will check it out, thank you very much
@E-bikeguy that won't damage my dual 48 volt batteries or 1000 w motor? More speed?
I recent bought a ridstar q20 and I wonder if this mod could be applied, definitely going to check it out 😵
Yes as long as your controller have shunts
How did it go? I have the 1000w 20a version was it worth it?
@notme9916 it was awesome in fact I sold that controller to a customer
i think it would be cool to just put the shunt mod on a switch. have a button for boost mode. that way my kids or whoever else cant run the boost.
That is a great idea and it will work
How much speed would you reckon this adds and is there any sort of a torque difference?
5% increase in speed and yes you will notice some difference in increase torque
Yoo bro! Your videos are sick! Can you suggest a controller or the specs I need to buy to get better acceleration pls, I've got a 1000w hub motor and I'm just using the stock controller it comes with
s.click.aliexpress.com/e/_msBjedO
Get the sabvoton 7260
Thank you
No problem I highly recommend it easy to use
Which one is it? It says 3000w I only have a 1000w
good stuff! was wondering, are controllers and batteries pretty much universal ? or do you need to match the same brands ? controller & bike brand for example
You can mix and match but most importantly you have to make sure the battery is compatible to the controller, like if the battery can handle the current the controller is asking for
Best wrapping in copper wire then you can remove it when you get tired of the battery flattening faster 😅💯🤠🤟
do you still have to squeeze them ? before wrapping them in copper ?
@@R3FL3X84 Just wrap the shunt ,looks like a staple
I know, right!!! 😅
what. My friend's situation I opened mine and saw four exits will not tell what to do 0:12
hey, i have an ebike from alibaba, 1000w hub motor, 52v dual batteries. 52v controller, if i was to do this mod what downsides or risks am i facing? because it seems like a 5minute mod to increase the speed and power but theres gotta be downsides if that doesnt come straight from the factory, im really tempted to do this if its safe for the bike overall
The risk, that will will be more current being pulled from your battery, make sure your battery can handle the extra current before the mod.
im new to e bikes, but i did see another video on this same trick, and the guy emphasized the importance of getting a heatsink for your hub motor.
Hey buddy, I have an Emmo Hornet X (48V). Do you know something about these bikes? I', wondering if I can use on this boke a 52v battery.
I'm not really sure but the only way to tell is to open up the controller and see what capacitor it has.
I fried my controller by adding too many lights, 51V in and 0v coming out. Manufacturer doesn't sell them, which one should I go with? 48v 500W motor...
Go with a sabvoton 7245 excellent controller and adjustable
Yiu sure that won't start a fire..all these ebike fires got me a lil skeptical 😩
No it definitely won't start a fire, it's all about how people a careless about their battery over discharging, overcharge them or a dead short in a cell by damage the controller won't start a fire itself
My guy. I own the same LY48V1000W controller. Recently Its been turning off my power randomly. The power will turn off but then come back. I've checked all the wiring and everything seems to be in place. Please help
Ok it sounds like a low voltage, do it only do that while acceleration or just all of a sudden?
@@E-bikeguy a little bit of both. It will shut off while it's on but not riding. And it will shut off for a few seconds but my LED display will show that it's low but then come back again to full. I hub motor will cut off and then work just fine. Am I looking at a faulty controller?
@crowsnestrc3551 that could be the problem, you said that your display show low than go to full check the battery it might be a indicator of huge battery sag before you rule out the controller is bad
I see what you're saying. I've been using my bike to go uphills alot. I live in a town with a lot of hills everywhere u go. Idk if that might have anything to do with the bike being faulty. It's a Sunday BMX build. I own the 48v 1000w controller and 1000w motor kit. I'm having a really hard time figuring this out.
My battery meter reads full. But my LED display. The "810" model won't even light up now
I've got 750wat fat tyre bike I'm going to use 1000wat 52v 20amp battery can I use 32+2amp controller I just want to go a bit faster I no the bike laws I would great full if that's OK thanks
Yes, I don't see why not lol
I have 1 question dying to no. How will it affect the battery. I saw 1 video where a guy shunts his control, but claims he had to replace fuse in battery. And iv seen others like yours and. No one mentions the battery. I have an old controller, and i want to try to shunt it but don't want to wreck our blow-up any fuses on battery.
It depends on the battery, since it will draw more amps so you you have a 30a or less battery I would not recommend it
@E-bikeguy 30 ok thanks i will keep in mind.
Hi some lads use 1000wat wheel 52v25amp ordinary controller 57,.mph it's overuse the bigger the battery more power say 3000wat as BMS really is a waist of time it's only I info to tell the current is drawn form each battery equal but if one of the wires burn on BMS it's long walk home the bike stops the lad next door to me builds battery and doesn't use BMS

@@E-bikeguy Thanks!
@@mrstans no problem 😊
I am sorry but I didn’t understand what the modification did. What exactly changed? Thank you
There's a shunt in every controller. Tells controler what amps its putting out. By adding solder. It fools controller into thinking its pushing less amps thar it actually is. But will increase heat. There's a gell you can buy to add to controler so it dissipates the heat better depending on controller it might not survive. Depends on misfits they used. Cant look that up too. But if add gell helps allot!
Yes we'll I ordered the original controller that he had on the bike before all this happen so h3 had a 80a 3000w controller on the bike, so I did the mod to the 1000w controller and I noticed it can handle more voltage but didn't know how much so I went to 52v to 60v went to the trials to test it out and it preformed great to my surprise it didn't get hot either, it was definitely a noticeable improvement in acceleration and too speed but has nothing on his new controller.
@@E-bikeguy puts out more power with no extra heat? What mosfits are in that bad boy?
You know what, I didn't even check that. I saw the caps and tried the 60v battery I just built went out in the woods to test it and it's just been good from there
@@E-bikeguy I was going to try on older controller..seen allot vids on. But never see a long term vid.. or performance comparison? Before and after . Just it's better. You enjoy the day.. and God bless brother.. good video.. loving my ebike.. 👊👊💪💪
Do you have any other kids or tips ?
Correction mods
Mods or tips
So if i were to do this mod on my stock controller and not change the battery or anything else, my bike will be faster? Is this just the speed limiter being taken off?
You will feel about 25% increase in acceleration 15% in speed
@@E-bikeguy i have a 250w ebike. Top speed is 20 mph.
@@E-bikeguyso i should find the controller open it up and solder 2 parts together? I would love to have a bit more speed and accelration. Nothing crazy cuz i ride in the city and dont want to get hassled by cops. This sounds like a perfect option for me. I can get up to 20 mph throttle and 24 mph pedal assist. So if I do this i should see around 23 mph throttle and 27mph pedal assist? And better acceleration?! Cuz thatd be perfect! Im new to ebikes so do you have a way i can contact you if i need help? Im not sure where the controller would be or what it looks like. Let me know thanks!
@@kaizen_creations you will be fine , trust me 🙂
@@E-bikeguy lol aight, ima just go for it, i think i found where my controller is located
I killed the motor hall sensor with a controller shunt mod because the motor apparently couldn't handle that much power and got too hot.
What kind of motor you had on your modded controller?
@@E-bikeguy One of those generic China rear wheel direct drive hub motors. The one i killed was from a 1500 watt kit(35 amps).
I'm pretty sure that my 1500 watt controller delivered about 2500 after the shunt mod.
the modded 1500 watt controller was about as powerful as my current unmodified 3000w controller
Oh wow, ok I having a similar problem with my son's 3000w kit, it overheated to so I tell him to be gentle till his new motor arrives, but the 1000w ebike it gets warm but not hot, mainly he is light and doesn't require alot of energy to move bike
@@E-bikeguy Then of course it would be good if you installed a controller in your sons bike, where you can limit the amps. The only permanent solution I can think of is magnetic cooling ferrofluid.
I also thought "then I'll just drive more carefully"
But it's so much fun that the heat will be ignored 😁
Unfortunately, my new display doesn't even show me the temperature anymore, so I have to guess when it's getting too hot, that sucks.
Even when these motors cooking at 100 degrees Celsius, they only feel slightly warm to the touch.
Lol right from time to time I'll stop and tell him to feel his motor and see if it's hot or not lol
And if you cut the 3 wires? What happen?
To my Thierry, a little go or no go at all
@@E-bikeguy ok. Thank you. I have a R25 performance Vmax and I want to remove the 20km limiter but I’m having trouble to do it! Any idea?
@Alexandre Madeira usually some controllers have a speed limit wire as a blue wire, just unplug the blue wire and it unlock the controller to go faster if not and you have a controller that do not have shunts like the one in this video then best option is to upgrade the controller.
@@E-bikeguy I don’t think it does because I disconnected wire by wire while using throttle in between to see if had any changes in speed and it haven’t.
What controller do you suggest for a 48v system with a 500w motor and a 10.4 battery? Thank you for you help
@Alexandre Madeira do the controller has a Waterproof connector for the hub motor?
If you run a 60v battery those caps are going to explode
Will this work on a totguard stock controller
As long as they have a shunt it will work
@@E-bikeguy I just now have it apart and I'm looking at it it is all in a slide box I don't have to get it to slide out of the box first I don't see anything easily on the end is it just a big capacitor that you are just sorting out so it goes straight through instead of through the big large capacitor
It's a brushless DC motor controller voltage is DC 36v product number JH3AZ2612DZQR
What if I've got four shunts
If they side by side you put them all together
@@E-bikeguy yes mate thay are side by side but 2 of them are taller than the other 2 as I've got a new controller and battery iam going to test it b4 I do the mod to see how it performs
Ok it should be noticeable difference in acceleration
Hi ebike guy, my name is Niamh I emailed you last week about how to unlock the speed delimiter on my ebike Raleigh array. Just hoping you can help me with that. Hope to hear from you soon.
Yes I remember, I also ask my supplier about this I'll find out something tonight
Can I send you my bike to do this mod I’d pay
Email me at theebikeguy@gmail.com
Looking for someone to build or upgrade a bike for me already 😢
No problem hit me up when you ready.
@@E-bikeguy I’m ready I can get a basic baba or Amazon bike send to u n pay u for the parts n labor n shipment to me where can I find ur email to send u the type of spec I want
Theebikeguy08@gmail.com. email me there
@@E-bikeguy I’d emailed u
What a janky setup.😆
3 volts is not enough capacitor overhead for 60 volts, and MOSFETs will burn out after shunt mod.👎 Buy an appropriate rated controller for battery and motor, or enjoy replacing them like toilet paper.
You know how old this video is? You talking like it was yesterday lol
@@E-bikeguy And you're still a food stamp mackin' mushmouth who don't know crap about electronics. Hey, hey, hey! 😆 Go vote for your big daddy Trump. There's another stimulus check just waiting for ya at his zipper.😁
Just get to the point !
🤣🤣🤣🤣 have to wait just like everyone else 🙄
Thank you! I learned something.....💪🦵🚴♂️
Ok , dang I just got your comment, sorry I replied so late
@E-bikeguy ....no worries.....I just watched today......I have watched every one of your videos since I subscribed....now going back in time to watch others.
Do you have a way I can message you privately
Jakoie08@gmail.com you can email me there
Does someone know can controller for 1000w take a motor of 1500w?
Yes it can with no problems 😊
