Amazing video! You might be the pro who could give me a tip ... I have a Razor E Prime III scooter, its controller has gone bad, I bought a generic controller to replace it. The battery pack has an XT-60 connector output (P+ and P-) and a charging connector (C+ and C-), both were connected to the original controller. The replacement controller does not have a charging input (from the wall charger) and charging output to the battery pack, so I have to connect the battery pack charging connector directly to the wall charger connector. Now no matter what the battery pack just does not output power to the new controller, the voltage across the XT-60 reads 0. It reads the full 42 V (charged for a 36 V battery pack) across the positive wire from XT-60 to the negative charging wire from the battery pack (P+ & C-), so I know the battery pack is still good. I searched all over the internet without any luck about how to fix this problem. Plugging in the charger to charge does not wake up the BMS to output power. There are sayings on the internet about shorting B- (which I don't have access to without opening the battery pack) to P- to wake it up. Since the original controller was connected to C+ and C-, if anything, the controller must have shorted C- and P- to turn on the BMS's output somehow, so I tried that but still having no success. Could you offer any tips on this? Many thanks!
I soldered DS together with F2 on the bldc and when I activate SL (Brake Low) I have a regenerative brake that slows me down very gently. F2 doesn't block the wheel as much as F3 and the EABS stops working completely at around 2kmh. I think this works best if your bldc controller doesn't have EBS available!
EBS brake in chinese controllers sometimes does not regenerate to the battery, and instead it short circuits the motor with some tiny load inside the controller which is known to burn both motors and controllers if enthusiastically exercised. Can you confirm that your battery voltage slightly increases during EBS braking? It would determine if your controller is capable of a true regen. I really would appreciate an answer! Thanks in advance
i have an cheap ebike and i added a voltmeter to it, when i try to EBS brake it increases voltage slightly and slowly, so does it regen to the battery?
I have the cheepest controller. It didnt even have wires for regen, but I found pins like this video. I also put ACS712 to measure the amp. It DOES regenerate 4A at top speed.
I have same throttle @ 17:55. Is it a straight wire through, ie. red 5V, black gnd, and blue (or green) signal? replacing a Swagtron EB6 throttle that had different colored signal wire.
@@user-A4YongJI i have a simalar controller i have the 60v pins on board what do i do with them i use 60v battery x2 60v pinouts on board brainpower controller 48v thank you
how do you know that X is motor deactivator? what's the difference with a low level brake? there is a way to distinguish ebs from the other braking functions? stunning channel
on that board your working on what do you call thoughs raised pathways on back of that board? I'm trying to find a match my old one Im not seeing very many like them can you point me the way?
Yeah it is, so long the alarm system works. You can have the surprise somewhere away from home and with no tools handy or know how to bypass it that it stopped working and instead of riding you will have to push it. I bought two disk brake locks with alarm. When they are moved the alarm is really loud. And cheap on Ali.
Hello friend, could you tell me what the VCC value is, with the orange cables connected? I need to repair my controller, yesterday by mistake I put the brake cable connected to the power connector y I'm seeing that that orange and black wire is connected to the same point as the blue wire on my screen, now I can't turn on my bike
@@EVCustoms I didn't mean the consumption of electricity, but the force that is delivered to the wheel, more precisely in the capacity and weight that it can carry. In old electrical engineering books it is written that higher speed means lower power. Lower speeds have more power, for example on a hill they can handle more weight.
Super informative. Noticed your controller has pads labeled TXD and RXD also. Trying to wire a UART display (sw900) currently controller is working on bike through throttle. Display powers bike on as it should (used the door lock and the alarm wires). Just need the transmit and recieve connected so display will stop batching about E10
Did you managed to connect it ?, I have different controler and display , in my controler there is RX pad for receiving data and TX for sending data to display
Interesting video , it is critical you understand when hot Rodding an electrical system which wires will need larger gauge wires to handle the added voltage or you will catch something on fire . You may need to leave it to a professional, the old saying , you know just enough to be dangerous.
don't worry, unless you mess with battery or phases cables all the other cable are low power or digital signal, you have to try extremely hard to get even some sparks
I would really appreciate an thank you if you would tell me which wire to cut to disable the ebs on the controler for the front motor. On slippery surfaces can be dangerous. Pleease.
Will this overheat and burn out the controller? Doing the k2 to ground connection?? Like say for instance i have cruise control will this be something I may be able to cruise at top speed ?
No way, I run 120% on dual 1000w front/rear with three speed swith for low and mid speed. And it runs cold. It's gonna get hot when I run 72v because 72v runs cold on 3000w.
Good video. For activate 60v I connect green wires togheter and for 48v I disconnect them? It Is right? Thanks in advance. I have another 48v controller (with 60v two PIN in pcb), and I'm looking for how activate 60v.
Dude, can you tell specific parts on pcb that could disable the speed limiter of the controller. ive got maximum speed of 25kph only. Want to bypass it without changing battery voltage to run at least 30kph.
Finally someone who gets right into a controller box.Good video.Do you have or plan to make a video of a Daymak Turbo Drive how to unlock its full potential controller?

Hi, is there any way to convert a generic 48v 500w controller into a 36v one? I really dont want to buy another controller because it takes a month to ship from china
Best mods to a jp 67.2v controller I think would be to bypass the LV shutoff I can detect when to stop and charge scooter also the automatic brake I want it completely off the jp does not allow that in settings it brakes instead of roll freely or regeneration into battery must have been off the menu and want to know if shunt is a good idea I’m curious but don’t want failure i’ll recommend them with the electric brakes to cut the wires. Trust me you should be able to apply the brakes with feel rather than wide-open stop.
Thank you for this video. It was quite good, but your video does not show clearly where you're connecting for higher speed, 120%. The other thing I'd like to know is whether the speed can be taken up to about 140%. Thank you.
@Will Swift Because, Top speed is not fixed. It varies according to design. So, if a particular design is underated, and if better methods are employed, above 100% is possible.
Hello. I bought an Yume M11 electric scooter. The scooter came with the rear light broken (the red diffuser ) and because was mounted on the rear fender after a while broke completely. Yume sent me a replacement but now I have no brake light. I changed the connectors and the led's are working either 2 either 3 from 5 total which 3 I presume should be for the brake light. I understood that the controller has a low and a high brake wire. Is the high 12V? I will mount a separate brake light but I see other connectors with only 1 wire. It means the wire is only +? If yes which one. And the ground is common with other ground wire? Please help me. [Smile]

Soi bought another controller and throttle and it was a 3 mode sine and I had all the wires I needed to plug into it to activate it. It started slowly spinning the back wheels and then itshotup in speed and I knocked it off the bike and again interrupted the pairing mode. On bothe try’s I set the circuit up again and nothing happened at all. The battery unplugged test showed 57 volts. But when I plugged it back in to test the positive and negative it only shows 20 something. It’s like the battery ant give its full power to the motor or controller side. Someone on the web mentioned motor lock?? Can u help me please I will gladly pay you for your time

The DC pin is for witch function ???

Thank you so much!

Hi, is there any way to convert a generic 48v 500w controller into a 36v one? I really dont want to buy another controller because it takes a month to ship from china
hi sir, what is the cause of may 72v controller? when i run the hub motor is reverse,

I have a 36v/48v controller, there no break light connecting wire... please help me to find
Best mods to a jp 67.2v controller I think would be to bypass the LV shutoff I can detect when to stop and charge scooter also the automatic brake I want it completely off the jp does not allow that in settings it brakes instead of roll freely or regeneration into battery must have been off the menu and want to know if shunt is a good idea I’m curious but don’t want failure i’ll recommend them with the electric brakes to cut the wires. Trust me you should be able to apply the brakes with feel rather than wide-open stop.
Thank you for this video. It was quite good, but your video does not show clearly where you're connecting for higher speed, 120%. The other thing I'd like to know is whether the speed can be taken up to about 140%. Thank you.
@Will Swift Because, Top speed is not fixed. It varies according to design. So, if a particular design is underated, and if better methods are employed, above 100% is possible.

Hello. I bought an Yume M11 electric scooter. The scooter came with the rear light broken (the red diffuser ) and because was mounted on the rear fender after a while broke completely. Yume sent me a replacement but now I have no brake light. I changed the connectors and the led's are working either 2 either 3 from 5 total which 3 I presume should be for the brake light. I understood that the controller has a low and a high brake wire. Is the high 12V? I will mount a separate brake light but I see other connectors with only 1 wire. It means the wire is only +? If yes which one. And the ground is common with other ground wire? Please help me. [Smile]
