I have a question if the motor is a 48v, and if I use a 24v or 12v battery, would it even work as will the motor even spin? I have tried a 24v so far it power up but the motor doesn't not spin and this a brand-new kit too? Need help any suggestions would be great thanks
can I modify that controller using an algorithm like PID control, and how to implement that using external system like microcontroller with an rpm sensor as feedback?
Thank you for uploading this trick. I always wanted to run motor directly from solar panel. The panel is rated for 40V max. I tried using boost converter, but motor fails to run after loading it. I tried to trace the circuit to find out the under voltage protection. While doing so, I already damaged one :( I will try this trick with other controller. Hopefully I will be able to run motor from solar panel + the controller. Thank you once again!
Just wondering. Do you know how to reverse the motor. By meaning. I have 3 speeds going backwards and 1 slow speed going forward. Can I just exchange 2 faces of the motor? (my motor is mounted backwards)
Hi, question. Is it possible to run those Chinese controllers with a higher than 48V voltage? And what modifications would it require? If for example I want to run them at around 80V. Thank you.
Many of this controllers are based on the same PCB, such that it is possible to change some components (Like in my video, if there is for example an over-voltage shutdown). Do you have a special controller in mind?

@@TengizAdamashvili If you got the 36V controller, you may change a voltage divider and it should run on 48V too, but more I would not give this controller, since the capacitors are probably not rated for higher voltage and also the MOSFETs may break through at higher voltage. Also the charge pump may be a problem then.
Good day, I need help. I have a controller MODEL KT36 / 48SVPRKD-SPS03 RATED VOLTAGE DC36V / 48V RATED CURRENT 22A LOW VOLTAGE POTENCION DC30V how to downgrade to (LOW VOLTAGE POTENCION DC25v) ???
I have a multi voltage controller 48v/60v/84v and it has 3 different low voltage cutoffs, 1 for each setting. is it possible to remove the 51.5v cutoff for the 60v setting without modifying the other cutoffs? I have 3 52v 18650 packs in parallel and I really dont want to rebuild the packs to avoid hitting the 51.5v cutoff right away as that would require buying a new charging unit to go with the higher voltage pack. thank you for your time and knowlage
Hello. I have a question, I have a 350w electric scooter with 600w max power. I have a 36v -48v - 350w and 18amp controller. Currently I have two 36v 10 amp batteries in series, which still gives me 36v but 20 amp. The question is. Can i connect the third one of this same power? 36v - 10amp. ? So I will have one large 36v battery but almost 30amp. Do you think it will drive safely? will not burn the engine or controller? Thank you for your help :)
Hopefully you just misspoke but 2 36v batteries in SERIES gives you 72v. If you are wiring 2,3,4 or 10 batteries in PARALLEL it will remain at 36v and multiply the amp hours, so you will increase the run time and current potential. This is completely safe as the controller is still receiving the same 36v and will only draw the amps it needs. Just be careful, I would recommend doing the research to better understand these basic fundamentals before making modifications.
Hey, i accidently bought a 48V controller for my BLDC motor. My battery is about 36V, and the undervoltage cutoff is at 42V, so i when i power it on the motor runs for a second or two and then stops. I don't mind having no cutoff at all since my BMS is already doing this job, but i can't rly find the adc, the voltage divider or +-3.3V (i'm not a total noob in electronics but i'm not an expert either). Could you give me any tips/help me to remove that cutoff please ? Thank you in advance.
Why does the controller have the voltage cutoff control? What are the implications of changing it in so drastic a manner? Why not use a 10-turn POT and make it adjustable? Basically, more background would be very welcome. Thank you.
The undervoltage lockout is used to protect the batteries from deep discharching. I chose the 12V, since I don't need the undervoltage lockout at all and this could also be achieved by connecting the ADC pin directly to 3.3V. But I wanted to show, how you can adjust the undervoltage lockout as needed for your batteries. A Potentiometer could be used, but then you need anyway to open the case if you want do some adjustments, since most controllers are waterproof and you won't cut out a hole there. Further to the undervoltage lockout, also the maximum current can be easly adjusted by changing the shunt resistor, such that you can transform a 48V motor controller completely to the one you actually need.
@@ttschabos thats mean that i can skip the steps in videos and connect the adc pin to 3.3V power source with same ground pin? If that true where is the adc pin how can i find it.please?
@@JerzyhanyIf you dont want undervoltage lockout at all you can connect the 3.3V source to the ADC Pin. To find this, you have to look after a voltage divider as in the video, that brings down the input voltage to the range of 2.0-3.3V.
@@ttschabos oh thats so easy now what should i do is to use a multimeter to find a pin that has approximately 3.3v then connect it with 3.3v thats share same ground . Is that all i need? Should i connect another 5v source to feed the hall sensors in the motor and throttle ? Sorry for distruping you with my stuped questions
@@Jerzyhany Ye its not hard, you can use a multimeter and watch out for points of around 3.3V between two resistors. The cut-off threshold at the cut-off voltage is around 3V as measured in my controller. So when you reach for example 37V, which is the cut-off voltage for a 48V controller, then you should measure around 3V. You have not to adjust anything else, the hall sensors are used for position feedback and have nothing to do with the input voltage measurement.
Hi brother, I bought electric car from China, but the speeding very low40km/h , how can I increase the speeding to 90km/h , the motor power 60v/1500 watts, the controller 60v /1500 watts ,
Hey, I think you wont get any faster, since the motor/controller power is not high enough. There is no hack for that, you need a motor with more power and an appropriate controller. Something around 5kW may fit your needs, but its hard to say if I don't know what car you bought and the other conditions.
@Block Chain Do you have a 36V controller, then it might work, but the problem is, that a boost converter has a efficency of around 90%, that means it will get pretty hot. A better solution would be to serial connect 3 lead acid batteries of the same type and same age. Your 24V battery is probably already a serial connetion of two lead acid batteries, if you get a third of around the same age, it will be a better and more efficient solution.
Hy. I have a E-Bike 500w 48 volt Motor and a baterry pack 48 v 10 amps and it charges at 52 volt, and the lover voltage is 41 volt. How low I could go with the voltage so that I don't distroy my baterry pack and my ebike? 40? 39? 37 volt maximum? I could modify my lover voltage directly from the E-Bike controller display. In the settings the lover voltage is 41 volt and I want to be 37 volt for a longer ride ,a bigger autonomy. Can I lover at 37?

How did you change out the sprocket? I have motor very similar to yours and can't seem to get the nut off to replace sprocket.
It is a left-hand thread nut, so you need to fix the axis and turn the nut clockwise to open it.
