Drew, greetings from the USA! I was just given a 2017 E300 that didn't work. I installed new 12V 7AH batteries and took care of some broken wires between the throttle and the speed controller and everything works now. I wanted to improve its performance and found your video. I am glad I did.! At first I was skeptical about your mod, but I figured I'd give it a go. I did your mod to the speed controller last night, and now I can get up a fairly steep hill and the speed is noticeably better! Prior to your mod, I could only get half way up the hill. I weigh 175 lbs. and the E300 zips me along no problem thanks to the mod. My 12 year daughter notices the difference too! She really flies on it! I recommend this mod to anyone with a stock E300! BTW I am a Mechanical Engineer if that matters to anyone reading this. Thanks again! Cheers!
You're supposed to use a 12v 9ah battery that's probably why you were having that issue
voltage and current is going to define perform, 9Ah is a measure of capacity, it determines how far you'll go (or not go in the case of old SLA batteries :)
Thanks for the feedback!! Cheers Drew
@@jonathanquezada1956
P=IV
Power(Watts)= I(Amp draw) x V(Voltage)
Power will be the same using either a 7 ah or 9 ah battery. Only difference is the power created will last a little longer with the 9 ah batt. So no increase in speed.
@@Hectorgutierrez you need a litium battery its gives more ah, don´t buy the old bulky ones.
I just found an E300 in the trash. I asked the people working in their garage if they were throwing it out. They said "yes" and that all it needs is new batteries. It is in fantastic shape. I guess their kids didn't really ride it all that much. I have been binge watching mod videos about the E300, and there certainly a lot of them. I need to buy some new batteries, make sure it really does work, and then I am doing this mod.
Awesome! If you didn’t get the charger go back and ask them if they still have the charger too!!! Cheers Drew
@@DrewFixIt Yeah, they had the charger with it. I'm just glad I got to it all before the scrap metal guys came around.
@@BryanWhite77 Nice, I call that a score!
@@DrewFixIt I got two new 9ah batteries and got the scooter going. The kids love it. I also did your mod and it definitely makes the acceleration better for a bigger person like me.
This is so funny. I also just found one in the trash. All that was wrong with it was the rubber of the throttle came unglued so it doesn’t turn the throttle anymore. The battery was good I turned it on and rode away. 😂 $15 charger and now I have another project… 😅
Thankx
This mod worked GREAT on both my E300 with OEM batteries! I weigh 160lbs. I used a 14 ga bare copper wire found in some spare home Romex wiring I had.
My soldering gun would not get the ends hot enough to melt my soldier SO I just used a small palm size butane torch I have.
It worked well to really apply the heat with its blue flame tip and quickly heat the copper end and the old soldier and new applied melted together. Be sure to use flux if your soldier isn't Rosen flux core.
I did one end at a time.
it works pretty well. had some trouble with the soddering but other than that, for how easy it is. it's worth it.
Just tried this hack and it works like a charm
Awesome, thanks for sharing the good news!! Cheers Drew
Your modification worked perfect on my E300. I was skeptical this simple modification would be so easy, but it went exactly as you showed. thank you for taking the time to post the video. Cheers😍😎
This is a great hack. It worked perfectly on my version 41 e300. Doesn’t bog down on grades like before. My only issue was getting the solder in place, but that’s a “not very electrically inclined” thing lol. Thanks for the video!!!
Hi Keeno, thanks for the feedback! Cheers Drew
If you see what your doing it’s just the motor ground yellow wire that directly connects to battery ground through that shunt which is always grounded anyways. Why not just hook yellow motor ground to black battery ground outside the controller for the same effect?
Totally worked man, good video thanks. Pulls my kids right up the driveway now. I even installed 2 new 12v 9ah batteries vs the 7ah.
Hi Pete, awesome and thanks for sharing!! Cheers Drew
It works better with that batteries? Is there a real difference in terms of performance with the upgrade of the amperes? Do you installed lithium or lead-Acid batteries?
@@AudiofiloChacharero I just ordered the replacement batteries for the razor e300 but made sure to get 9ah rather than 7ah. They are sealed batteries. As far as the Mod with wire, I used the piece of copper from a white roll of 120v I have. Soldered that and it pulls my kids up the driveway now. Wouldn't do that before. Hope this helps you out.
Thx for vid, lithium batteries are cheap now and saves about 10lbs of weight!
it looks like theres already a shunt on the other side. do some of them come preequipped with a shunt
i have an e200
Hi Luke, that is correct! What you are doing is adding to the shunt so that the combined new shunt can pass more current than the original! Cheers Drew
Sorry Drew, I was on vacation. So I put two new “Expert Power” EXP-1290. 12V. 9ah/ 20HR. THANKS
Yes so in the case of my Fiido T1, the problem is the opposite, too much power - there is no finesse in the throttle - its on/off. I want to put in a switch from the handlebars with a wire going down to the controller. In one position the original resistor value is in circuit as normal (with full power). In the B position a higher value resistor will be selected to give a lower current and hence lower throttle.
Hi Steve, understood. I’m not sure why razor didn’t put a variable speed controller in these scooters! Cheers Drew
Is there a cheap easy way to put power tool batteries in these..I can't stand waiting for it to charge..Me, my lady & daughter love riding together but we want to go on longer rides..Thank You
Hi Mate, it really depends on what tool battery’s that you want to use! A couple of 12V ones in series would be a really easy modification! Cheers Drew
WOW man!! This just what I needed I guess I can do the same mod on my Uber Scoot 300 since it looks very similar to Razor and my uphill ability is very poor.
Sounds good, let us know how you go with it!! Cheers Drew
Hello I did this, but I’m just getting a click and light on. It was working before fine.
Oh never mind it work good to cause the break lever got wet and dry it it work now it pulls me up hill I use a 12 ga soild wire perfect
for anyone not a complete noob. 3:40 is the actual start of the mod
The wheelchair has 2 motors. Each is 250 watt 24v. Battery is lead acid.
Thanks for sharing this great to know this I'll do my 300 thanks again. Have a good one enjoy life 😊
Thanks mate! Cheers Drew
Loved the video! Never thought you could modify the scooters like that! Can this simple modification work on the lesser "E100"? It goes about 10 miles an hour. Thanks for sharing your knowledge....👍😎👌
Hi Alan, unfortunately the E100 only comes with a 100W motor and the core platform is small with a little rear wheel. I suggest upgrading to either a E200 or E300 which will give you a good base platform to upgrade from. Cheers Drew
@@DrewFixIt hey, thanks man. Even though I can't use the mod on my E100, I still enjoyed watching the upgrade. Thanks again...😎
Hi @@alanpules4105 if you like that one perhaps you might like this Razor one I did playing with some different custom lithium battery packs: ruclips.net/video/vHbdyS-3Hrw/видео.html Cheers Drew
This is beyond amazing. Thank you
Glad you like it! Cheers Drew
I just tried this mod and no change. I also changed the batteries with new ones (12 volt, 7 ah, lead) and a new motor (higher wattage). My sons charger barely lasts 10 minutes and struggles going up hill. Im frustrated...could it be the speed controller?
My brother just gave me he’s E200, it would work right if I did your instructions?
Hi Jamie, yes it will work, however by comparison to the E300 you will not notice as big a difference as the E200 has smaller wheels and therefore accelerates faster out of the box! Cheers Drew
Great video thanks! Any thoughts if this would also work on the rx200? And can the shunt just be a piece of wire? 14 gauge maybe?
This worked great for my son’s e200 and soon going to mod my brother-in-laws e300 I gave him. The question i have is, is there any long term side effect?
Hi Austin, I have not noticed any substantial long term impact, however everything is going to work a little harder and hotter, so one would expect a little impact! Cheers Drew
@@DrewFixIt tx for the quick reply and the video!
Awesome improvement
Sure was!! Cheers Drew
Have you tried fitting lights and a bell to it yet?
I think it's a legal requirement in most states.
No mate! Cheers drew
wow thats great i have an old e100 in the back room it was working yrs ago and the kids just stopped going on it it was brand new and they only went on it twice and when i tryed to charge it it wouldn,t so im quessing it needs new batteries but what i was wondering is can you do that to that one because it only goes about 7 mph
Thank you so much it worked !
Sweet, thanks for sharing mate! Cheers Drew
@@DrewFixItI had a problem , it worked great but my scooter now randomly turns off when I’m going up an incline then will turn back on like 30 seconds later do you know what the problem might be ?
@@DrewFixItand then it will make a click and it will turn back on again
Good day Drew....getting ready to do your hack....wondering what lithium battery and charger you might suggest?.......
I did this yesterday on my daughters e200. It didn't improve anything unfortunately. Scooter is exactly the same
Extra torque is fine, but can you tell me approximately on many more mph you get ? Thank You 😊
The top speed is only around 10% faster, the big difference for me is the increase in acceleration!! Cheers Drew
Try a smaller sprocket
Thx for the video. This is officially above my pay grade. 😆
Mine too, but that didn’t stop me having a crack 🤣🤣🤣
Right so I tried this and it didn't have any effect on the performance of my e200
Hey drew. About to do this. Just a question, will this hurt the scooter in anyway? Do I have a chance of melting the motor with this or hurting the batteries? I have an e200, if that helps.
Hi Mate, you are effectively over riding the built in limiter, however in reality you’re only going to give a percentage boost of 10 or 20 percent so the chances of damaging your motor or batteries is minimal. My scooter as an example is still running fine with this mod personally! Cheers Drew
@@DrewFixIt Thanks.
Thanks!
Thanks Matt, truly appreciated! Cheers Drew
Can this be done also to the controller of an electric wheelchair? What's the percentage of improvement for the speed and torque? Will it not heat faster? Will it not take so much from the batteries that will end up reducing the battery capacity per charge? Hope you can answer my questions and guide me, Sir.
Hi Mate, I would not personally do this to a wheelchair controller. Cheers Drew
@@DrewFixIt Alright. Thank you, Drew.
Hi, I have the same model razor scooter & completed this as per instructions, but 1st ride the cutout tripped & continues to do so in the 1st 1min of riding. It was not doing this b4 mod, so it causes the issue, anyone have a view?
Hi Michael, I would suggest that your additional shunt is a little too fat! Cheers Drew
Hi Drew, Followed your instructions on this mod for an e325 and it worked great at first, way more power. While testing on the first ride It then started causing the reset button to trigger which in turn turns off the machine. I can hit the reset button and then turn the machine back on and then it works fine for a while but then it will trigger again. Any thoughts on why this is happening? Can I bypass this by unplugging any of the connectors? Any fixes I could try? If it continues and not that I want to but can I solder this off and would it in theory return to its original function? Appreciate any advice, thanks!
Hi Mate, what is happening is that you are now pulling more current and it sounds like it is right on the limit of that fuse. I would suggest putting a fractionally larger fuse in! Alternatively, go fractionally smaller (in diameter) with your bypass link that you have added to the controller board. Cheers Drew
5:33 do you solder the 2 bulbs together where the wire meets one side or are the bulbs still separated where one side of the wire is soldered at
For some reason when I twist the throttle it won’t go im pretty sure I did everything correctly can u help?
Gonna try this on my son's.
What about the scooter's with 3 speeds?
Hi Mate, I have never opened up a speed controller with 3 speeds to know. Cheers Drew
What range are you guys getting with the 24v 7ah stock battery?
I got about 6 km but the batteries are 7 years old.
And the rider weight is about 78kg. 😅
Hi Gerard, 10km is about normal. So I reckon you’re doing well out of 7 year old batteries! Cheers Drew
That's what I'm getting too with 4-5y old batteries, and it is time to get some new since the service tech guy told me that with new and a bit stronger batteries performance would increase a lot and with this mod, would be even more, so get yourself a pack of new juice and good luck!
How you bypass the annoying kick start on this scooters
Hello I change two new batries and I have the same problem every day my problem is the very low range can some one help??
I found one of these by the side of the road for the trash and took it home and the batterys were done and I think the controller didn't work so I'm going to run it straight to a 24 volt lithium battery from another old scooter and just use a toggle switch and wire directly from the motor to the battery.
Hi Stephanie, nice find! To do what you want to do you will need a relay as per this video I made on another scooter: ruclips.net/video/MMEqKcgljdw/видео.html Note - without a relay your switch will die sooner or later! Cheers Drew
@@DrewFixIt That would be nice to have because then I can use the throtte switch instead. I got it to go down the road like this but the battery is not good. i only got like 200 yards and it died. do you know a good place to order a 24 vilt lithium battery? I'm thinking at least a 10 amp hour one.
So after the mod, how much faster than 15 mph was the top speed of the scooter?
Same top speed but much better acceleration and hill climbing.
Can I do this to my super 1000w uber scooter this heck? Or how can I make my goes faster?
I'll never unhear soouullduurrr😅
Hi Jesse so glad that you have a lasting impression!!! All jokes aside, glad that you got at least a bit of a giggle :) Cheers Drew
I love the accent honestly. Great video and very informative!
Hi. Can you explain the engineering behind this hack. Why does it work
Hi Zubair, the thickness of the original shunt limits the amount of electricity that van flow through it, think of it like a skinny water pipe for which we then add another pipe alongside it! Cheers
Can you do this with the E95? Or is the Interior the same
Hi Mate, the E95 will have a different speed controller as it is lower capacity. The principle though should be the same so you will just have to find the current limiting shunt yourself on that PCB! Cheers Drew
Great videoo Drew, I have just bought one of these scooters off of gumtree, and I am wondering, does this mod decrease the range of the scooter? I'm thinking more torque, more speed = less battery life? Have you seen any noticeable difference in battery life since doing this upgrade? I ask because the stated range of the scooter is around 10 miles on a full charge, and I will probably be using at least 6 miles when I'm travelling about. While the increased torque would be a blessing, will I be sacrificing that distance? Thanks! Michael
Hi Michael, I have not noticed any significant decrease in range! Cheers Drew
The range should be the same unless you are using the extra torque to go uphill faster instead of pushing the scooter.
I used a 486 watt hour battery on an ebike with a 1500w motor giving me 17km at 50km/h. The same battery on another ebike with a 300w motor riding a 25km/h also lasted 17 km range. It could vary if the vehicle and riders are lighter.
@@gerardr4869 It will definitely reduce the range if you are noticing more power. That hack allows more current which means it will use more current. More fun though and worth doing unless you fry your motor.
@@nickdarling5557 usage of more current is also providing more travelled distance but the higher the load , a battery gives less usable energy
So less range.
What is the approximate power in watts after this mod? Just wondering if it's better or worse than switching to a 36v controller.
My guess is 350W. Cheers Drew
so they basically are using the shunt as the limiter
Correct! Cheers Drew
Hey what's up man I'm late to the party but I bought two razor rambler 12s do you think this mod would work on it also of not do you have any tips on getting more speed out of them. Thanks all the way from Texas.
Hi Ray, I don’t know. It just depends exactly what speed controller Razor have used in this model. What I would do is open the speed controller up and have a look if it’s he same or not!!! Cheers Drew
@DrewFixIt yeah I'm gonna need to do that problem is absolutely nothing on RUclips and how to on the rambler 12 from my understanding is its not as simple as unscrewing a few screws to get what u need to things are solder inim not even talking about the speed controller once I get into it ill let you know what I find
My scooter E300s don’t have any power, run but when a I get on it do not move, that I need to replace the motor or is another part giving this problem?
Hi Jorge, perhaps you need new batteries! Here is a video
ruclips.net/video/_ZaYluDs5Ns/видео.html Cheers Drew
Drew i was wondering if i can just rip the shunt off or would it just damage my scooter?
Hi Mate, it is actually a current limiting device, so … ripping it off will stop the scooter running at all! Cheers Drew
Drew, hi from Canada East Coast, thank you for the great video:) I have a Razor E300 as well and I am wondering if the shunt mod will trip my circuit breaker? thanks keep up the wonderful videos:)
Hi Deborah, my circuit breaker has tripped once or twice since I did this nearly a year ago now, however I was hammering it really hard up a hill! Cheers Drew
@@DrewFixIt Thank so much Drew ..just what I wanted to hear👍
I only get to just 2 miles with it and I bought 2 new battery of 12v please what can it be the problem please.
What is the battery capacity?
Hi friend, I'm from Mexico and I really don't understand English very well, my question is... the trick is for what really? What does it take away and what benefits us? more speed for what? Thanks friend, I wait for an answer
More speed and more torque. Cheers Drew
Hey is it possible to replace the battery and the motor in a razor scooter that is a e100 and replace it with e300? My scooter is a very small scooter tho it’s one of the kid ones that goes 8-10mph
Hi Mate, when you consider the amount of money that you would spend on these upgrades I suggest that you would be better off finding a second hand Razor E300! You will then have a very solid platform/base to move forward with! Cheers Drew
@@DrewFixIt that’s true. But would it be possible?
@@everleighshortsedits9500 anything is possible, I just don’t understand why you would do it! Cheers Drew
@@DrewFixIt it would only cost me $80 and a new one is over $200😂❤️
@@everleighshortsedits9500 go for it then!
Very interesting hack but does it burn the motor in time? Or drain the battery faster? Im mostly scared about the motor, can it get burned or something?
Hi Daniel, my motor is still running fine!! Cheers Drew
Battery should drain slightly faster because of the increased current
Can you modify Gotrax scooter?
You can do anything with enough patience!
@@DrewFixIt I'm looking for the right person or youtube video to try increase my gotrax speed and more
This hack worked beautifully....until my board overheated and lit the whole scooter on fire lol
Haha!!
Hi Drew love this idea. I used to own a Grey razor e300. But now I upgraded to a razor eco smart. So my wife has a first gen E200 belt driven with a variable speed thumb throttle. I was wondering if this trick would work with this mod?
Hi Mate, yes this mod should also work on the Razor E200! Cheers Drew
Would this work on a mongoose z350
Sooo is this going to mess up the scooter and possibly kill the battery/ motor quicker?
Hi Billy, mine is still going strong! Cheers Drew
G'day Drew, im still very new to these Escooters.
If that one bit of wire already on the green side of the circut board is the speed Limiter, Then wouldn't adding another wire on the other side do same thing, or keep it as limited as it already was?
It adds more material to that circuit thus limiting the "amount" of current flowing through.
Hi mate, adding more material to the circuit actually has the effect of “increasing” the current! Cheers Drew
is that little wire supposed to be resistive? bc i have that too. i mean ig adding more wires increases current lol but is it negligible?
resistance = resistivity of material*length of wire/cross sectional area. to increase current use a material with a really low resistivity, as short as possible and the widest cross sectional area
Drew, I was given an E300. The batteries were bad so I got new ones. The motor runs and turns the wheel, but when I put weight on it it will not turn the wheel. As soon as I lift the rear wheel and it has no weight on it, the wheel turns. Any idea what it could be.
Hi Nick, what band of batteries did you put in? Cheers Drew
Same problem.
What I need to do to fix my razor E300s it run but no power or don’t move when I get on it
Check the battery's individual voltages with a voltage meter. One may be bad.
what about the zing c20?
How fast will this mod make it go from the 15 mph
Hi Michael, the main improvement is acceleration and ability to climb hills!! Cheers Drew
Hi Drew Simon , razor 300 charges for short period of then it turns green I brought new batteries but still
Hi Simon, I suggest checking your connection between the charger and the scooter! Cheers Drew
@@DrewFixIt thanks 🙏
Hello Drew, I'm hoping you can shine some light on my situation? I have the exact scooter and the first time I did the procedure it worked awesome! However it stopped having the extra power after one ride. I thought it was due to my crappy soldering job so I did it again but nothing happened and then again!!!! What are my options ? I weigh close to 200 lbs I really need that extra hmph thank you solo much. Your video was so easy to fallow your a great teacher.
Also the batteries are brand new
Hi Jay, It’s hard for me to say without looking at it, however perhaps in your case you might be better off upgrading components such as
ruclips.net/video/wPVQ6zAvOmg/видео.html Cheers Drew
Hi Drew, I installed two new 12v 9 Amp batteries.
Hi Nick, what brand of batteries did you install? Thanks Andrew
U need lithium
Has anyone tried the e300 original controller with 36v ? Or has anyone seen the capacitors voltage rating inside the controller?
Hi Gerard, you will blow the capacitors and FET’s! Cheers Drew
What battery do you have?
Hello. I have an E300 that sat for a long time. After being on charge all day I still have no power with throttle. When I have it plugged in and hit the throttle I hear a click from what feels like the speed controller. I put a voltmeter on the batteries and I'm only having about 8 volts. So I'm assuming the batteries need replaced regardless? I just figured it would at least turn the tires with no weight on it.
Hi Korey, your scooter need new batteries. Here is a video I have done on how to change them: ruclips.net/video/_ZaYluDs5Ns/видео.html Cheers Drew
Saw a video that said you need at least 21 volts coming from the batteries for the tires to move 👍
The speed controller cuts power at 20.5volts +/- 0.5v this is so you don’t over discharge the batteries. However, if a 12v led acid battery only charges up to 11.5, it is considered worn out and needs to be replaced.
will this mod work for an e200s?
How many gauge or what size is that copper wire u used?
I used 14 ga home solid copper wiring but 12 ga home wiring might give a slight more power, not sure.
I need help to derestrict my e bike. It has an ananda 3614dsc-5ns0 controllers. Pls help!!!
Hi Mate, without knowing the specifics of the controller in your ebike, I suggest installing a higher capacity unit in as I did here with this scooter: ruclips.net/video/wPVQ6zAvOmg/видео.html Cheers Drew
Would dis work on a razor e325 ?
Hi Mate, it just depends upon what Speed Controller Razor fitted to you model. Best to open it up and have a look inside to see if it looks the same or not? Cheers Drew
I did and it looks the same but when I did this it did not work
I have a razor MX650. Would this same method work on it?
Hi Mate, depends on the speed controller in that model. Open it up and have a look if similar design! Cheers Drew
Does this work for a e90?
Does this remove the kick to start. I have an e100
Hi Joel, you need an E200 or E300 to do this hack! Cheers Drew
wonder if it fry out the board?
Hi Mate, my boards still fine! Cheers Drew
Will the battery drain faster?
Hi Peter, one would assume so given that you are accelerating harder, however I genuinely have not noticed much difference in run time! Note, however I did put a fresh set of good quality batteries in this scooter just before doing this mod! Cheers Drew
Is this worth doing if you have no hills?
Yes - it certainly helps with acceleration!
Will this work on black label e90?
Hi James, only on either a E200 or E300! Cheers Drew
How fast does it go with modifications?
More torque but not more speed
How much more mph does it go after?
Hi Mate, top speed on flat is about the same. What really changes is the acceleration and ability to go up hills! Cheers Drew
Would it work on an e100
Hi Mate, e100 come with only a small motor, are painfully slow and are just not up to the job unfortunately. Suggest you upgrade to either a E200 or E300! Cheers Drew
How is this mod still going, has it damaged the controller or motor yet

Hi Johny, Interesting. Did the fuse blow or did the controller just cut out? Cheers Drew
@@DrewFixIt so I have no idea if there is a fuse but I don't think it blew all that would happen is it would run normally as long as I didn't put weight on it but as soon as I stood on it the light on the power switch would cut out... After removing the copper wire and reassembling it I've had no issue with it. I believe it's a 2016 e200 Razor
