Meanwhile.....back in China, a factory owner is smiling and rubbing his dirty little hands together thinking "Thanks Dave!"

[@batsoupe]

Then that little factory owner in china laughs all the way to the electrical engineer responsible for the design, and realizes Dave just bypassed a failsafe specifically designed to reduce the amount of strain on the cheap motor and possibly increase the overall run time on the battery.

[@edwardkasprowicz3176]

Dave, great info and good work. Can U do the same with a mobility scooter, like a pride celebrity X scooter to gain more speed?

[@bruzza3031]

Supposedly you can do it on electric bikes scooters anything but you take a chance of burning up your controller so I heard

[@jb678901]

Recently purchase Uberscoot ES04 300, which came with chain drive and 250W motor, lead acid 24v battery supply (2x12V) and a 24V controller. Just installed a 350W 24v motor, and it required no modifications (just fit). Reused the motor power plug as the metal connector contacts were already on the wires of the new motor. Just had to remove the plug from the old motor and extract the old contact leads from the plastic plug (clipped internal stops on the old metal contacts were easy to depress with a small screw driver in order to extract them). Then I simply inserted the new contact leads into the plastic-housing plug. Note: matched the colors of the vertical and horizontal contact leads within the plastic plug so that the motor direction is kept the same. This has already dramatically improved the hill climbing torque of this well made scooter. I used heat shrink before inserting the lead contacts to avoid shorts and better moisture proof connections (did this for the whole length up to the motor housing. Also, I added some hot glue to the backside of the plug for reinforcement. Next up...replace the lead acid batteries with 12000 MAh Li-ion branded battery pack with a BMS as part of the battery unit. I am staying with 24V...I do not want a speed demon for me or the kids. Just a better hill climber. In addition, to upgrade the controller to 24V 500W. This should better handle peak power demands with the Li-ion pack. Lastly, keeping the rear sprocket the same...no change other than adding some marine grease. Again, no need for more speed on my part here. It all fits like a champ. Battery unit was about $70, controller about $20, and the motor about $50. Scooter originally cost me $250 new, so all in I have a decent and legal scooter for just under $400, with a good range.

[@asainlee6690]

[@billylaplant3342]

I tried to do this on my e300 but there was a black plate covering the board. I couldn't get it off, so i put the metal on the bottom, where you said it would be hard to do. I just taped a paperclip to that metal bar (speed limiter) and it didn't seem to make a difference. Is there a way to get the cover off the board and is the way I did it safe and should it work?

[@grandtheftauto1233]

This is called a shunt mod. You shouldn’t do this a sit will completely remove all current limits on the controller. You will blow the mosfet once too many amps are drawn. Better mod is to add solder to the shunt on top the board, so only increase the currently flow and not make it unlimited

[@theshadow5472]

Can it also be done on a controller of an electric wheelchair? What's the percentage of improvement for the speed and torque?

[@tmatheson]

I’ve seen a lot of these shunt videos but what I want to add is that before you do anything. Measure the resistance in ohms across the shunt. That way you have a way to measure how much solder to add. If you double the resistance for example, you should get double the speed or max controller speed whichever is greater.

[@mistersunny3636]

I guess you have to lower the resistance to increase power. And one should know how to measure a few milliohms. Also speed is always voltage dependend, not amps.

[@tmatheson]

@@mistersunny3636 I mean reduce not double, double the solder is what I meant.

[@leoaquarionewprofile2981]

great video man, i have been watching your videos and i feel to ask you a question, more than a month i'm struggling to make my mobily scooter a bit faster. tried many things and nothing, but seeing you video, i realised that would be the only thing could work, but i opened my controller S DRIVE but I CANT IDENTIFY where to make tha change, to add on it or remove completely. So kindle do you mind if i send the picture of the controller and you tell me where is located that? I would appreciate a lot if you could do it for me...

[@simontaylor138]

[@andrewmead1434]

what if you jumped a potentiometer across it so you can adjust the speed to your preferred settings

[@Kalash9777]

make a video like that

[@1HandyLad]

No, you need to modify the circuit heavily. It uses TL494 PWM controller that you need to pull a datasheet of and see how to control the speed in regards to this particular design. Direct wiring a pot across a shunt isn't going to work.

[@XJOCK69]

Ty Dave. After that quick fix on E200 how much mph did you get out of it? I’m bout to do mod. Before I do. I need to know MPH please. My E200 on a good day does maybe 10 mph

[@TheMightyClam]

Hi. Nice informative video. I'm considering doing this on my razor e300 - do you have any idea what the extra drain on the batteries will be after the mod? I'm concerned I will be limiting the already short lifespan of the batteries between charges. I'm already getting less than 30mins on a typical use 😂. Thanks!

[@jynx8501]

I’d recommend just trying it and if it does effect your battery life, go from there , replacing the battery shouldn’t be the hardest thing with one a little larger I can only see the size and it not fitting being the problem , however if you were putting a new computer in it then we’ll you’ve fucked it in my eyes because I have no idea what I’m doing at that point

[@DaveHere]

Some of your comments I can't reply too. Depending on the thickness of the wire it can increase the speed by 2-5 mph. The thicker the wire the faster. That also means it could cause your motor to overheat or your processor board to burn up. It is the size it is because of the safety of the equipment.

[@DaveHere]

***** I was in it for the torque when I did it.

[@DaveHere]

***** got ya. Definitely avoid this hack if you want distance. It will drain your battery quicker. Quick interchangeable batteries would be cool. Good luck

[@Mr65Mee]

I was wondering if another set of batteries plugged to the charging plug would work. Like having a small backpack with batteries and wire to plug to the scooter.

[@DaveHere]

+Able Reyes depends how you hook them up. increase the voltage and you'll fry the board. increase aph and the scooter will run longer.

[@GibParadox]

I'd say your best bet at extending your range is to reduce friction to a minimum. Make sure your bearings are not rusty, properly greased, etc... same goes for the chain (which tends to gather dust and dirt). Also, if your wheels are not solid (ie. there's air inside), make sure the pressure is right. If they are solid, I'd try and fit the thinnest ones available (the smaller the ground contact, the smaller the friction). Finally, when you start from a 0 speed position, give the first push "the old fashion way". This saves the motor from having to "start the motion" (which uses a lot more power than just maintaining the speed).

[@4479hotrodmustang]

It worked on the razor mod Bella scooter it goes up hills with me on it and it didn't before. But my question is how do you do the Bristol razor scooter it's different.

[@XJOCK69]

Rayden B I’m bout to give it a go. We’ll see?? 👍

[@michaelwilkes0]

didnt see any comment actually explaining why, so here is what is going on. That wire is not a current limiter, its a current sensor. Dont cut it, leave it there and add the other wire as well. This works because it tricks the controller. The resistance is now lower, and the controller measures the current incorrectly and thinks its allowed to pump in more the current. Making the wire bigger than a paperclip is probably not necessary. In fact the paper clip is probably more than necessary. The controller is likely already running at about 80% duty cycle to hold full speed so you just need to divert about 20% of the current around the original shunt to get 100% duty cycle out of the controller. Im just guessing those percentages from experience, I could be wrong. Now remember, the manufacturer programmed that exact current limit for a reason. Its not like they just didnt want you to have fun. They know that past that limit, stuff starts getting unsafe. By all means do the mod, but remember that full throttle is now a turbo mode that should be used lightly. If the motor, speed controller, and batteries are cool to the touch, keep pushing it. If they get hot, back off a bit.

[@robertreid3806]

"So the controller sees half the current" [through the original shunt wire]. Er no! The controller cannot measure the two currents through the original shunt and your new one separately. The controller just 'sees' a single electrical path from A to B. But now that path has a marginally lower resistance. This change opens the gate in the mosfet slightly more, allowing greater current to the electric motors, thus feeding them more juice and making you go faster. One thing to remember is that the manufacturer would have selected the mosfet for the original design current value. So any big increase risks exceeding the mosfet's rating and it will overheat and fail in a couple of seconds. Solution? Increase the mosfet's heatsink size to disperse more heat (small improvement), or way way better: swap out the mosfet for a higher rated one and bolt it to a big heatsink! Personally, I'd accept a modest improvement in speed (by using a thin extra shunt) and retain some of the original reliability.

[@chopperbadcompany759]

I have an old pride mobility scooter any help on making it faster?

[@euro9115]

I have to say, duct taping a paper clip across the circuit board is definitely NOT a good method. Soldering a small gauge wire 'jumper', similar to the same gauge as the original jumper, across the same contact points on the board is how it should be done. Best to use an insulated piece of wire and soldered to the circuit board. It sounds like some of the responders have actually tried the paper clip and duct tape method, or simply wired to the wrong contact points. As for enabling or disabling the extra current carrying capability, one could install a S.P.S.T. (single-pole, single throw) toggle switch on the outside of the battery compartment (close to the controller board) and soldering short 26 or 24 gauge wires to the two contact points on the board. Then you could have the increased torque with the switch in the ON (closed) position when you need to go up an incline, and switch OFF for riding on level terrain. I just acquired a (free) used E300 and started to refurbish it. Someone left it sit outside for a long time, as all the screws were badly rusted, as well as the chain ... I had to drill out the screws. I've already purchased a new chain and two new batteries. The motor, tested out fine, but the throttle control does not want power it up ... need to troubleshoot the throttle and brake controls and wiring next. If the controller still works, I'll try the mod and add the toggle switch to provide the current increase, and hopefully, have the best of both worlds ...

[@freshmaker5]

Please reply to this if you pull It off and make a video. Is doing these mods safe?

[@dubstar939]

Worked for me

[@ovidiuovidiu5966]

I am not familiar with the scooter board but the shunt must be a current to voltage to the processor. So if you add another resistor in paralel you will fake the processors feedback regulator and it will not work propperly. I do not know where this meal jumper is on the electrical schematic. If it is on the battery it is a protection not to destroy the battery from overcurrents if it is on motor is acurrent sensor.

[@gregst.martin4889]

Losing weight will help you get more speed also and a bigger battery helps with this hack

[@shammyali3895]

i tried it but the wire that comes from the charging port to the processor the wire on the processor end same black wire snapped and my scooter doesnt charge but wen i turn on the scooter smoke cums out and the plastic cover on the wires gets burnt

[@RobbiRocks]

Dave buddy, how does adding one more little peice of wire etc across those two sections increase speed etc? As those two bits are already joined together on the green side of the circut board

[@jkstdstang]

I believe the idea is to increase the current path by making it thicker essentially although he is talking about bypassing it altogether it sounds like. Beefing up the existing trace with solder would be a more reliable mod as his method will most likely pop the mosfets on the PCB at some point from too much current.
