Thanks so much. After first watching your videos a year ago, I finally re-watched them and got my KLS7218S to work with my Cyclone 3000w mid-drive. It was also my first attempt at battery building (20s5P), so the first power up was nerve racking. The motor didn't turn at first and just jittered, but I swapped two of the phase wires and it worked! Using your videos and the manual, I was able to get it programmed. Thanks again!
Hi, We are using KLS8430H to run the PMSM. But we are facing an issue with Identification angle process. Angle identification process is not completed getting Identify err. Requesting your support for us to proceed further
Provably you are using a quite big motor so I suggest that you increase the "Motor Nominal Curr" from 80 (default) to 90 and try if your identification angle process if finalises ok.
Hello, I have a electric scooter with 72181 Kelly controller , but work with 60v lead acid battery, can I connect 72v lithium battery (84v) to it without changing anything or need to change programming parameters?
72 from the controller reference number means that it can work up to 72V nominal battery voltage. (Max. battery voltage around 85-90V). But I recommend that you confirm it by reading the manual. In order to make the controller work properly with a different voltage battery, or different kind of battery, you NEED to change the parameters at the controller for the new battery.
I have usb cable for lbmc and golden motor controllers, this cable work on kelly controllers? Do you have link of software for I connect and change parameters?
@@vahidganjvar3812 The cable you need is a RS232 to USB adapter cable. Or if you have a computer with RS232 connection then just a RS232 cable. You can download the manual and software from here: kellycontroller.com/support/
@@gonzalop.chomon327 It's pretty clear what he meant. You said in the video Kelly does 80 to 200 Amps but it only pulls 80A from the Battery. The 200A are the Phase Amps that the motor sees at low Rpm. 80Ax72V is a max of 5760 Watts. If you just say 200A it could mean 200Ax72V wich would be a crazy 14400 Watts. So it's important to distinguish Battery Amps from Phase Amps.
The speed it is not only a matter of the controller; It is the full setup: battery, motor and controller. All of them powerful enough to reach and maintain that speed and motor able to reach that speed.
Hello, I'm working on a motorcycle conversion project. I'm using a Kelly KLS 7275h and I can't get a connection to my bluetooth app. The LED on the dongle is blinking and when I try to connect it with my phone it stops blinking but I get the error "open Flash failed" in the App. Has anyone had a similar problem?
@@gonzalop.chomon327 Thank you for your answer! I already messaged the guys from QS and they will send me a PC connection cable, hopefully this will work.
Hi Harry, here you can download the manual with schematics for the KBS-E wiring: kellycontroller.com/wp-content/uploads/kbs/KellyKBS-XUserManual.pdf If you have any doubt let me know.
I Gonz, i see your video 2-300 times, but in something Im wrong:
I I am Carlo and write from Italy. I have a problem with the Kelly controller paramenter ! I use a Kls 7218 s, a mxus 3k turbo 8000W peack, and a battery pack 72v 28Ah 2160 Wh (compost of 160 samsung cell 35 E 18650 ) at last, a Daly bms 72v 20s 150 Amp. The sistem dont' work! I change all the possible parameters on kelly's App. But Noting!!! So I ask me, and ask you : -1 : is possible that the color of the fases ar wrong..??? if i change the color for try, i broke somenthing?? and -2:Do you have, and do you can, send me all the true app parameters, for a pretty use? I don' t know ...I am disperate.....the seller of the kit, is a very bad boys...and i don' t know more what i can do. If you can help me ….I'm becaming mad! Carlo,
As you already have played with the parameters in your controller, first make sure that in the App you are using hall sensors parameter (Your motor has hall sensors) Then you need need to make the motor turn. There is 36 different combinations of how to connect the cables of the motor and the hall sensors. It only works in 6 of those 36 combinations. this is done by try and error. When you see that the motor turns (does not matter what direction) DO NOT TRY TO GO FULL SPEED. After that you have to do all the proceedings explained in the video.
Gonzalo, I am thinking of buying a sensorless Kelly controller but I am not sure because I am trying to reach 100000rpm and I dont understand the formula they use. they say eRPM = RPMxPolePairs. Their sensorless controller is rated 17000eRPM therefore if I want to spin a 4pole motor, I could only go as high as 17000/(2 pairs) = 8500rpm. Does that make sense ? Thanks in advance for your time.
Hi marcotstrere, Yes you are right. As per Kellycontrollers info their sensorless versions are up to 17000 eRPM so, yes if your motor is a four pole then up to 8500 RPM. And looks that they do not have a HiRevs. version.
Hello Gonzalo. Do you use a pre-charge resistor on your wiring or just a XT90 anti spark please ? I have a KLS7230S and a 48v Hailong battery and a MXUS 4T motor.
Hello, I bought Kelly KLS 7215N Controller. However, I am having problems with the connections as there is no user manual. There were parts that I benefited from your videos. But I can't get the engine speed to the screen. "(8) Meter: Copy signal of hall sensors." I'm connecting. Which pin should I connect? I would be glad if you help.
YOu should always note which Kelly you are describing, for they make many controllers, with many different software programs. How do you like the KLS series? I do like my KEB.
Thank you for the tip. I added that info on the description, but you are right I should said it on the video, but I just forgot... The biggests differences that I find between the KLS and the KEB are: - Less noise from the motor - Smoother responses (due to more parameters that can be tweaked) - More functionalities - But still missing the PAS (Pedal Assist Sensor) function.
Dear friend, please help me. I connected everything and a red light and a green light came on. The engine does not turn when I turn the throttle and I connected everything properly. I would appreciate it if you could get back to me as soon as possible.
Usually the red light will flash with a code, 3-2 or 4-3 or whatever. At the end of the manual you will find what every code means. If you can not find it let me know the code and I will try to help you.
can anyone tell me about pin wire 15 on here an where it goes its a foot switch does it need closed to pin 11 or left open to work i have a 7230s regards
Hi Magnus, Before you make identification angle procedure, the motor has to be able to turn, meaning that the color combination of cables is correct. And you have to choose the correct parameters at the controller. Check full videos.
Hi ... I have a small problem with the Kelly kls 120A controller I have the drivers, the program, everything, but I only managed to connect to the controller once. then it started showing me the program that the controller is not turned on or the RS232 cable is disconnect. but the controller is on, the cable too .. please help. thanks
I don't understand, i used your very usefull video to link my kls7212s to my mxus xf19 but it don't work. I linked the 5 hall wires, the 3 throttle wires, the power wire to the plus of the 52v battery, the 3 phases wires. When i first plug the battery and the power cable i had a green light flashing on the controller, i immediatly tryed to use the throttle and i felt a beggining of reaction like a very little impulsion every time i started to activate the throttle, avery very shy move then the green flashing light turned to a flashing red like this: 3 times flashing then 4 times flashing again and again. If someone can help me, i checked all the connections, nothing wrong
@jeanterine4712, 3-4 flashing light means: Angle Sensor Error: It can be: - Connected the phase wires or the hall sensors wires on the wrong combination - Damaged hall sensors - Identification angle procedure not made or failed - Wrong setup of kind of sensor I bet for the first or third reason ;)
hii this is ariz , im using kelly7245nc controller. i have been changing all the parameters , but the motor speed isnt gradually decreasing but it stops in 1 second. The 48v 110ah battery drains faster and how can i improve my battery effeciency by controlling the sudden stopping of motor
If your motor turns and then suddenly stop abruptly, it is possible that you have not done the motor identification sensors angle properly. That can cause big consumption as well. Try to make it again, it should turn smooth and nicely.
I received that "black" controller and screen without any manual or other kind of info... and I was not able to find the controller manual. Anyway it is a quite simple controller that I believe it is made in India and vastly used in rickshaws. About the screen it is made by APT: aptdevelop.com you can download the manual for the screen form that webpage.
Thanks for this vid. My controller shipped without a bluetooth adapter. I have an USB adapter on my android that will turn the USB C into USB compatible with Kelly's cable. Will the android app see and connect to the controller this way? When I run the app, it asks if I am using the wire cable or bluetooth, so I suspect it will work. Haven't tried it with the controller yet.
Hello I was wondering if there’s a reason why the Kelly Bluetooth modules don’t with the kbs controllers ? I would like a way to track watts and change my setting easily
I am very happy with them. But I understand that they are difficult to program as they have a lot of fields that you can tweak... Actually more than 100 options.
Hey Gonzalo, have you ever had any issues with the computer cable connection? A few months ago I was able to get it to connect after a number of attempts and then set up the parameters, but lately I can't seem to make it work. Every time I try to open the Kelly app it says "no power, or cable not connected". Do you have any advice?
Yes, sometimes I had difficulties with the cable. Usually after several attempts disconnecting the battery and so on I was able to connect. Try to add a ferrite ring to the cable because it maybe noise problems. Heard that using Android app instead of PC app works better but never tried myself.
Fantastic tutorial series!! Following it closely but I have a slight problem... it seems KellyController only has the KBS-X version not the KBS-E version, so it's capping me at 60v for over voltage on a 72v setup :( - any chance you have the link you used to download the programming software? I have the same controller
@@gonzalop.chomon327 you know what it was, i made a mistake and ordered the 48v initially... It has two stickers on it, one says 7218 and the other says 4818... Lol - just placed order for 72v as well. Great videos man!!
would there be an issue if the controller power pin gets power before B+ does? This is how I have my contactor wired but I thought I would ask before I begin bench testing. Thanks!
@@gonzalop.chomon327 thank you. BTW I just got my kelly controller programmed a few minutes ago thanks to your videos. I'm going to make a video (already have a few episodes available) and I will link to your video here!
Hello Gonzalo - I’m curious on how to use the foot switch pin with the battery charger as you describe. I have a three pin charger connector with red and black going to the battery for charging. There’s also a blue wire that plugged in to the factory bike controller to prevent powering the system with the charger plugged in. I don’t know how to connect this circuit - can you please advise? Thank you!
@@gonzalop.chomon327 ok - it’s not 12v but I see the concept looking at the circuit diagram in the Kelly manual. I’ll keep working on it. Thanks again!
At 3:15 my motor just jitters and does not make a full turn. Any idea what it might be caused by. Hall sensors seem to be legit and also the main phases seem to be ok. My controller is KLS7212S and the motor is mxus 3k
Hi Garbagej, For what you say, I think that the problem is that the motor phase wires and hall sensor wires are not connected in the right combination. You have to check the different combinations of wiring the motor phase cables and hall sensors cables in order to find the correct ones. There is 36 different possible combinations, only 6 of them make the motor work, 3 in one way and 3 in the reverse.
Great vid!! You mentioned around 10:55 about Max Output Fre. Mine is also at 1000. So this can be only requested to Kelly to increase it? Is it to increase top rpm or speed of motor? Thanks!!
Yes it is possible to request to Kelly for higher frequency controllers if necessary. But that does not mean that your motor will go faster if your motor is only able to go to a certain speed with the voltage supplied.
@@gonzalop.chomon327 hi there! Do you mean you can request a specific "model" of controller or do you mean that Kelly can program the controller higher?
When I turn on my Kelly Kbs-X it goes green, I turn the throttle and the motor starts to turn then cuts out after a 1/4 turn and light flashes red, how do I solve this?
Can you please advice me with some issue? I installed this controller with a 2000W 72V BLDC HUB Motor and when i give full Throttle it ramp up the power and than slow down for a few seconds, and than ramp up again. it looks like there is some amperage limitation in the controller, but in the app i set the AMP to maximum. is there is some advice how to solve it? thanks for your great service
It looks to me that the Sensors Identification Angle procedure has not been done or has failed. So first can you check that? If the problem persists let me know and we look other parameters issues.
@@gonzalop.chomon327 i did the identification a few times. after many tries i replaced the motor with a new one, and thr problem stay the same. after it slow down once the re led start to blink. it gives the code 3,2 "internal reset". can you please help me understand what it going on?
@@neworld4ever I think it can be problem in the identification angle or faulty wiring. That causes the controller to reset. It can be as well a problem inside the controller of bad connections. Check everything, make sure that after doing the identification angle procedure, the value is back automatically to 85. Hope it helps.
@@gonzalop.chomon327 the identification angle is automatically back to 85 each time i set it to 170. the wiring is good. is there is a way to set the identification manually? I think that if all this tries don't work i will go in to a conclusion that there is a problem inside the controller, right?
@@neworld4ever No there is no way to do the identification angle manually. And if it changes to 85 means that is doing it correctly. So look for something else. The only things elses I can think of are: - To check the different combinations of wiring the motor phase cables and hall sensors cables in order to find the correct ones. - There is the possibility that the controller is faulty.
Depende cual sea el controlador a veces se puede cambiar la programación. Si no fuera posible los Kelly son de lo mejorcito que he probado a un precio razonable.
Hello, we have the problem with our vehicle that the speed display shows about 5 km/h too little. Unfortunately, we have found in the Kelly manual no information on how we can adjust the speed display on the "Kelly KAC7235n". Does anyone have a tip where we can set this in the software? Which parameter we should change ? Thanks in advance, Christian
No, this controller does not have field weakening. As far as I know (I don't know all) Kelly controllers doesn't have that feature. Anyway, as a rule of thumb if the motor needs to run more that 10% of its working time on field weakening point, it is better to use a higher KV motor, or increase the system voltage in order to achieve higher rpms. Else the system will run with low power efficiency.
You can setup the regeneration different ways: No motor brake, Intelligent automatic regen brake (using brake switch), Analog regen brake (using a potentiometer or a hall sensor throttle/pedal), Release throttle regen brake and as well you can setup, slope braking aid and direction change regen braking. You can see how to set up on next videos: Part 2: th-cam.com/video/_if9dnVkr6U/w-d-xo.html Part 3: th-cam.com/video/ITP6mey2eCk/w-d-xo.html
In order to give you some advice about it I need detailed information. But before of all you need to know this: A battery powered electric system depends on the battery power. So if you want more power the best way to start is to have a more powerful battery. There is different ways to pimp up controllers and motors so they can give more power that what have been designed for, but first the battery has to be able to give that power to the these devices.
@@danabuksis6231 I suggest bigger battery if you want more power, but may depend in your application, if you need it to run just for a few minutes (10-30) it may be enough battery (at the costs of battery life) With that little info is not much more I can recommend you.
salut j'ai effectuer Appairage des phases mai le moteur saccade et ne veut rien savoir et sur mon Controller la led rouge reste allumée merci de me venir en aide svp merci
Sorry I do not understand French, but with the translators it says: "Hi, I have paired the phases but the motor jerks and doesn't want to know anything and on my Controller the red led stays on." You need to find out the right combination so the motor turns. There is 36 different combinations and it only works in 6 of them. When it turns do not fully accelerate the motor before you make the sensors identification angle protocol.
Software for this controller model does not has that option. But you can change the relation between speed/torque control by modifying the Kp and Ki values. You can find info about it in the last video: th-cam.com/video/ITP6mey2eCk/w-d-xo.html
@@automoto95 First try the motor with the already set values from factory. If not enough acceleration then increase the Kp value in 400 steps and the Ki value in 10 steps until you get what you need.
I've seen them all! One thing to think about: what you are programming is a Kelly KLS controller. Other lines, like older KBS have very different parameters. Maybe you should specify that in the title. Thanks again for a great video series!
@@OpenEmoto Thank you for the tip. It is specified in the video description. Anyway the old software is simpler than the new one, so if you are able to program this one the other one has less parameters but their function is the same as in new model. (There just some little simple differences)
Hello Gonzalo I have a Kelly kbs-x 72v 55amp controller I’m trying to wire up to a cyclone 3000w motor, could you give me a run down on what PIN numbers go with what for throttle, acceleration switch, 12v out? I’m having some trouble figuring this out as I’ve seen different things. I’ve read the manual but i want to make sure, as well as do you think I’ll need the pre charge resistor? Or instead can I use a capacitor parallel with the battery lines into the controller ?Thanks for the help in advance !
Hi Cristian. - First of all here is where you can download the latest manual: kellycontroller.com/wp-content/uploads/kbs/KellyKBS-XUserManual.pdf - On pages 10 and 11 you got clear schematics about the connections. - For the throttle: Pin 20 is ground (usually black cable in throttle) Pin 4 is 5V (usually the red cable in the throttle) and Pin 3 is the signal from the throttle (usually white cable in the throttle but can be other colour) - For what they call "acceleration switch", I think they refer to a dead's man switch, latter they call it in the manual foot switch. I talk in the video about it. You can use it or not as it can be enabled or not. - (Pin 11) 12V out, this to use just in case that some sensors may require 12V instead of 5V (Do NOT use it to feed other vehicle systems as it gives very little current) - With 72V I recommend that you use a resistor precharge system. - You can add a capacitor at the entrance of the controller if the distance from the battery to the controller is very large. But this will make even more necessary the precharge system.
@@gonzalop.chomon327 for the precharge system how exactly can that be set up do I have to have a contactor? The battery will be in a back pack with a cord about 3 feet long, would that distance be long enough to be able to just use a spark arrest such as a capacitor?
@@cristhianhoyos7863 The precharge system is in order to charge the capacitors that the controller has inside, if you add more capacitors then there is more capacitors to be charged... so more need of a precharge system. You can buy connectors that have that precharge system incorporated in them, that maybe the easiest solution for you. here: https: //s.click.aliexpress. com/e/_9fjDxU (without the spaces)
@@gonzalop.chomon327 I couldn’t use that link, but I think I found something similar? It’s a anti spark xt90 would that be what I need ? Bc my battery will be disconnected very often so I’m not sure how I can do a regularity charge system currently I’m using xt90s to from the battery to the controller, if I replace those with anti-spark connections will that work ?
@@gonzalop.chomon327 thanks you’ve been a life saver ! I have one more question ! In the manual on like 15 and 16 it says it has a boost switch and and eco switch, I know you said there’s a part of that in the programming, but what pin wires would I need ? It’s not very clear on that part haha
Hello Sir, I am currently working on a 3 wheel project. I am working with a Kelly KLS7212N model driver. I am working with a 3 wheel vehicle of approximately 400 kg.(Gearbox ratio 1:10) The vehicle cannot go uphill without a booster gear and overheats, reaches about 90 degrees Celsius and protects itself from excessive heat. How can I overcome this problem, which parameters should I change?
There is some parameters at the controller that can be tuned in order to reduce the motor temperature. Between others the main parameter you can tune is: to reduce the overall power, but as you commented, you have power problems. What makes me think that the problem maybe that the motor is not powerful enough for your application. Can you give information about the vehicle: Weight, speed you want, aerodynamic coefficient, frontal area, etc. So it is possible to calculate what is the motor power for your needs.
Gonzalo , i have controler Greentime 84v 1500 w did you know how to program that controler and with wich cable ? problem is angle 60 degree it must be 120 degree If you know you will make me happy :)
Hey, can I programme the controller to have something as eco mode to consume less power and have speed restricted to +-25km/h and other configuration with full power and switch between them in real time? Something as chinese e-scooters have. Thanks!
@@gonzalop.chomon327 Yes I finally find out too that it has three speed, but didn't know about custom program to each one, that's great! I have another question which I can't find anywhere. Do you know the main difference between KLS and the "legacy" KBS? KBS is slightly more powerful, 55A/130A, against 50A/120A in KLS. As I understand, the software and functionality is different, but I don't know the details. I want good throttle response and KBS should have torque throttle mode. Thank you again :)
@@thepretiso The main difference is that KBS ones are square wave and KLS are sine wave controllers. Software is more less the same. While in the KBS you have 3 modes to choose from (Speed, Speed/Torque and Torque) in the KLS you have direct access to edit the PID numbers.
@@gonzalop.chomon327 Oh really? there is no mention on Kelly's site that it's square wave, I thought it is also sinewave. So what do you suggest is best option for e-scooter? I am worry that KLS would lack that acceleration punch from the start, what do you think? Also I think that configuration of KBS is easier. Ill check that part3!
i have a kls it has a tft screen there is no sm4a or rs232 port will i need to go via julet connector (tft screen connector?) hardwire a bt adapter on there?
I suppose that then it is already being programed for a certain vehicle or a motor/battery set. If it does not have a programing connector then you will need to open it and add it if you want to change parameters.
I think I just found the schematic you need for the connection to the Julet connector: kellycontroller.com/wp-content/uploads/kls-s/KLS-S-APT-Communication-adapter.pdf
@@gonzalop.chomon327 Thank you im waiting on the bluetooth adpater as the pc method didn't work, yes the shecmatic is perfect thanks, will let you know the progress
Hi Jean, this KLS controller models does not have PAS sensor input chanel. There can be a way to connect a PAS, Torque, Force or similar sensors and made them work, but I do not know how.
Afaik the only way to really get PAS support on the Kelly ESC is to pair it with a Cycle Analyst v3 display from Grintech. To do that you'll need either (easier way) the grin tech external molded shunt or do a CA hookup to the controller motherboard. Then you setup your pedal assist parameters on the cycle analyst.
The BBSHD has 88 effektive Motorpoles,does it mean i have to write 44 at motor poles, And which Temp-sensor do i choose when there is a 10K in the BBSHD??? Thank you
The BBSHD motor has 4 poles so it will be 8 for the "Motor Poles" field. About the thermistor, this controller accepts the KTY84-130 (970 - 1030 Ω) and the KTY83-122 (1000 - 1020 Ω) so I believe that a 10K thermistor will not work for this controller.

Hi Gonzalo, thanks for the tutorials. wondering whether u be making a wiring video as mentioned? ive got a KBS72181AE and the manual reads 'All contactors or circuit breakers in the B+ line must have precharge resistors across their contacts', but it doesnt seem like you have and im hoping there will video to enlighten this matter with other systems like the regen braking. tqvm for reading
No I have not used any prechager system, that is why you can listen the sparking on the videos. The model used for the video is quite small so it is possible to skip the precharge at cost of replacing connectors or switches occasionally. But for bigger controllers precharge resistor or other system is a must. You can find info about the regen braking on the following videos: Part 2 English: th-cam.com/video/_if9dnVkr6U/w-d-xo.html Part 3 English: th-cam.com/video/ITP6mey2eCk/w-d-xo.html
@@gonzalop.chomon327 hi again Gonzalo. I wired my KBS72181AE like u did and applied very low throttle. The motor turned for a few seconds but then the controller overheated and shut down. After letting some time to cool I tried again but the Led indicated there's too much voltage into the controller. I suspect it could be my wire running from the battery to the pink wire 7 being not the right size and resistance maybe? What's the right awg then? Thanks
@@guumballl Pin 7 is just the "switch on" signal, it does not need any kind of big load cable. If controller heated up in just a few seconds, something must be done badly.

And of course make sure that the battery voltage is not over the controller limit (90V for your model)

If the battery is able to deliver 30A as you described, then set it at 30A (You need to make the calculations to transform it to % ) For more acceleration change the PID numbers. I talk about it at 3rd video.

Hi Vahid, Kelly has dozens of controllers models, check their website.
The motor speed depends on motor characteristics and voltage supplied.

We are using KLS8430H to run the PMSM. But we are facing an issue with Identification angle process. Angle identification process is not completed getting Identify err. Requesting your support for us to proceed further
Provably you are using a quite big motor so I suggest that you increase the "Motor Nominal Curr" from 80 (default) to 90 and try if your identification angle process if finalises ok.
@@gonzalop.chomon327 Sure will try. Thank you
what throttle is that and or what throttles work with kelly controllers?
Any signal from around 1V to 5V will work.
You can use a potentiometer or a hall signal throttle.
Hi Gonzalo.. Can you help me to connect the controller
Hi Patricia, what controller model do you have?
Hello, I have a electric scooter with 72181 Kelly controller , but work with 60v lead acid battery, can I connect 72v lithium battery (84v) to it without changing anything or need to change programming parameters?
72 from the controller reference number means that it can work up to 72V nominal battery voltage. (Max. battery voltage around 85-90V). But I recommend that you confirm it by reading the manual.
In order to make the controller work properly with a different voltage battery, or different kind of battery, you NEED to change the parameters at the controller for the new battery.
I have usb cable for lbmc and golden motor controllers, this cable work on kelly controllers? Do you have link of software for I connect and change parameters?
@@vahidganjvar3812 The cable you need is a RS232 to USB adapter cable. Or if you have a computer with RS232 connection then just a RS232 cable.

Kelly 80-200A? No 80A Battery and 200A Phase
Sorry, I do not understand what you mean.
@@gonzalop.chomon327 It's pretty clear what he meant. You said in the video Kelly does 80 to 200 Amps but it only pulls 80A from the Battery. The 200A are the Phase Amps that the motor sees at low Rpm. 80Ax72V is a max of 5760 Watts.
If you just say 200A it could mean 200Ax72V wich would be a crazy 14400 Watts.
So it's important to distinguish Battery Amps from Phase Amps.
OK I understand now.
It is a 80A continuous current and 200A peak phase current. (I did not meant phase current)
Hello friend, i need high speed (can reach 120-140kph) square wave 72v(84v) controller, can you suggest me a controller please ?
The speed it is not only a matter of the controller; It is the full setup: battery, motor and controller.
All of them powerful enough to reach and maintain that speed and motor able to reach that speed.

I Gonz, i see your video 2-300 times, but in something Im wrong:
I I am Carlo and write from Italy.
I have a problem with the Kelly controller paramenter !
I use a Kls 7218 s, a mxus 3k turbo 8000W peack, and a battery pack 72v 28Ah 2160 Wh (compost of 160 samsung cell 35 E 18650 ) at last, a Daly bms 72v 20s 150 Amp.
The sistem dont' work!
I change all the possible parameters on kelly's App. But Noting!!!
So I ask me, and ask you :
-1 : is possible that the color of the fases ar wrong..??? if i change the color for try, i broke somenthing?? and
-2:Do you have, and do you can, send me all the true app parameters, for a pretty use?
I don' t know ...I am disperate.....the seller of the kit, is a very bad boys...and i don' t know more what i can do.
If you can help me
….I'm becaming mad!
Carlo,
As you already have played with the parameters in your controller, first make sure that in the App you are using hall sensors parameter (Your motor has hall sensors)
Then you need need to make the motor turn.
There is 36 different combinations of how to connect the cables of the motor and the hall sensors.
It only works in 6 of those 36 combinations. this is done by try and error.
When you see that the motor turns (does not matter what direction) DO NOT TRY TO GO FULL SPEED.
After that you have to do all the proceedings explained in the video.
Gonzalo, I am thinking of buying a sensorless Kelly controller but I am not sure because I am trying to reach 100000rpm and I dont understand the formula they use. they say eRPM = RPMxPolePairs. Their sensorless controller is rated 17000eRPM therefore if I want to spin a 4pole motor, I could only go as high as 17000/(2 pairs) = 8500rpm. Does that make sense ? Thanks in advance for your time.
Hi marcotstrere, Yes you are right. As per Kellycontrollers info their sensorless versions are up to 17000 eRPM so, yes if your motor is a four pole then up to 8500 RPM. And looks that they do not have a HiRevs. version.
Hello Gonzalo.
Do you use a pre-charge resistor on your wiring or just a XT90 anti spark please ?
I have a KLS7230S and a 48v Hailong battery and a MXUS 4T motor.
Recomendable on your setup but not mandatory as you are at quite low voltage.
@@gonzalop.chomon327Thank you Gonzalo.
Hello, I bought Kelly KLS 7215N Controller. However, I am having problems with the connections as there is no user manual. There were parts that I benefited from your videos. But I can't get the engine speed to the screen. "(8) Meter: Copy signal of hall sensors." I'm connecting. Which pin should I connect? I would be glad if you help.
Here you can download the manual for your controller: media.kellycontroller.com/new/KellyKLS-NUserManualV2.9-1.pdf
Do you know if the kbs x controller can work with the Bluetooth adapter? Either the one Kelly makes or a Bluetooth module like a Hc-06?
I think that it is not possible to program the KBS controllers models with Bluetooth adapter, but I suggest that you ask Kelly directly.
YOu should always note which Kelly you are describing, for they make many controllers, with many different software programs.
How do you like the KLS series? I do like my KEB.
Thank you for the tip. I added that info on the description, but you are right I should said it on the video, but I just forgot...
The biggests differences that I find between the KLS and the KEB are:
- Less noise from the motor
- Smoother responses (due to more parameters that can be tweaked)
- More functionalities
- But still missing the PAS (Pedal Assist Sensor) function.
Hello. i have controller KLS 7230s, where to connect the wire 6 from the controller when connecting the temperature sensor
Dear friend, please help me. I connected everything and a red light and a green light came on. The engine does not turn when I turn the throttle and I connected everything properly. I would appreciate it if you could get back to me as soon as possible.
Usually the red light will flash with a code, 3-2 or 4-3 or whatever.
At the end of the manual you will find what every code means.
If you can not find it let me know the code and I will try to help you.
can anyone tell me about pin wire 15 on here an where it goes its a foot switch does it need closed to pin 11 or left open to work i have a 7230s regards
The pin 15 can be used as an activation/deactivation switch.
I talk about it at 2nd part video: th-cam.com/video/_if9dnVkr6U/w-d-xo.html
When I do the identification it will end with 3 buzz and then 2. Do you know whats wrong?
Hi Magnus, Before you make identification angle procedure, the motor has to be able to turn, meaning that the color combination of cables is correct. And you have to choose the correct parameters at the controller. Check full videos.
Hi ... I have a small problem with the Kelly kls 120A controller
I have the drivers, the program, everything, but I only managed to connect to the controller once. then it started showing me the program that the controller is not turned on or the RS232 cable is disconnect. but the controller is on, the cable too .. please help. thanks
Try to connect to Android system instead of PC. I think it works better.
@@gonzalop.chomon327 okay,thank you
I don't understand, i used your very usefull video to link my kls7212s to my mxus xf19 but it don't work. I linked the 5 hall wires, the 3 throttle wires, the power wire to the plus of the 52v battery, the 3 phases wires. When i first plug the battery and the power cable i had a green light flashing on the controller, i immediatly tryed to use the throttle and i felt a beggining of reaction like a very little impulsion every time i started to activate the throttle, avery very shy move then the green flashing light turned to a flashing red like this: 3 times flashing then 4 times flashing again and again. If someone can help me, i checked all the connections, nothing wrong
@jeanterine4712, 3-4 flashing light means: Angle Sensor Error:
It can be:
- Connected the phase wires or the hall sensors wires on the wrong combination
- Damaged hall sensors
- Identification angle procedure not made or failed
- Wrong setup of kind of sensor
I bet for the first or third reason ;)
Why are you multiplying the pol pairs by 2 to get the right amount magnets? Shouldn't you multiplying by 3, because the motor got 3 phases?
It refers to the physical motor poles not the "electrical" motor poles.
hii this is ariz , im using kelly7245nc controller. i have been changing all the parameters , but the motor speed isnt gradually decreasing but it stops in 1 second. The 48v 110ah battery drains faster and how can i improve my battery effeciency by controlling the sudden stopping of motor
If your motor turns and then suddenly stop abruptly, it is possible that you have not done the motor identification sensors angle properly. That can cause big consumption as well.
Try to make it again, it should turn smooth and nicely.
Thanks for the great video! I was wondering what the black controller is? I have the same one and I am trying to find info on it. Thank you
I received that "black" controller and screen without any manual or other kind of info... and I was not able to find the controller manual. Anyway it is a quite simple controller that I believe it is made in India and vastly used in rickshaws.
About the screen it is made by APT: aptdevelop.com you can download the manual for the screen form that webpage.
Thanks for this vid. My controller shipped without a bluetooth adapter. I have an USB adapter on my android that will turn the USB C into USB compatible with Kelly's cable. Will the android app see and connect to the controller this way? When I run the app, it asks if I am using the wire cable or bluetooth, so I suspect it will work. Haven't tried it with the controller yet.
Yes, you can connect by USB to Android system.
Hello I was wondering if there’s a reason why the Kelly Bluetooth modules don’t with the kbs controllers ? I would like a way to track watts and change my setting easily
The KBS controllers uses the old software version, so I suppose that is why it is not compatible with the bluetooth connection.
I don't know anyone who is happy with Kelly controllers. I bought a couple and then bought something else.
I am very happy with them. But I understand that they are difficult to program as they have a lot of fields that you can tweak... Actually more than 100 options.
@@gonzalop.chomon327 congrats, you are the first.
Hey Gonzalo, have you ever had any issues with the computer cable connection? A few months ago I was able to get it to connect after a number of attempts and then set up the parameters, but lately I can't seem to make it work. Every time I try to open the Kelly app it says "no power, or cable not connected". Do you have any advice?
Yes, sometimes I had difficulties with the cable.
Usually after several attempts disconnecting the battery and so on I was able to connect.
Try to add a ferrite ring to the cable because it maybe noise problems.
Heard that using Android app instead of PC app works better but never tried myself.
Fantastic tutorial series!! Following it closely but I have a slight problem... it seems KellyController only has the KBS-X version not the KBS-E version, so it's capping me at 60v for over voltage on a 72v setup :( - any chance you have the link you used to download the programming software?

At 3:15 my motor just jitters and does not make a full turn. Any idea what it might be caused by. Hall sensors seem to be legit and also the main phases seem to be ok. My controller is KLS7212S and the motor is mxus 3k
Hi Garbagej,
For what you say, I think that the problem is that the motor phase wires and hall sensor wires are not connected in the right combination.
You have to check the different combinations of wiring the motor phase cables and hall sensors cables in order to find the correct ones. There is 36 different possible combinations, only 6 of them make the motor work, 3 in one way and 3 in the reverse.

Mine is also at 1000. So this can be only requested to Kelly to increase it? Is it to increase top rpm or speed of motor?

Yes it is possible to request to Kelly for higher frequency controllers if necessary. But that does not mean that your motor will go faster if your motor is only able to go to a certain speed with the voltage supplied.
@@gonzalop.chomon327 hi there! Do you mean you can request a specific "model" of controller or do you mean that Kelly can program the controller higher?

That causes the controller to reset. It can be as well a problem inside the controller of bad connections.

Hope it helps.
@@gonzalop.chomon327 the identification angle is automatically back to 85 each time i set it to 170. the wiring is good. is there is a way to set the identification manually?
I think that if all this tries don't work i will go in to a conclusion that there is a problem inside the controller, right?
@@neworld4ever No there is no way to do the identification angle manually. And if it changes to 85 means that is doing it correctly. So look for something else.

- To check the different combinations of wiring the motor phase cables and hall sensors cables in order to find the correct ones.
- There is the possibility that the controller is faulty.

The vehicle speed calculation on Km/h or mi/h is carried by the display, not by the motor controller.
You should check the display manual.

Does this controller have wield weakening?
No, this controller does not have field weakening. As far as I know (I don't know all) Kelly controllers doesn't have that feature.
Anyway, as a rule of thumb if the motor needs to run more that 10% of its working time on field weakening point, it is better to use a higher KV motor, or increase the system voltage in order to achieve higher rpms. Else the system will run with low power efficiency.

Hello dear how i can increase mor power to motor? and more power throttle?
In order to give you some advice about it I need detailed information.
But before of all you need to know this: A battery powered electric system depends on the battery power. So if you want more power the best way to start is to have a more powerful battery.
There is different ways to pimp up controllers and motors so they can give more power that what have been designed for, but first the battery has to be able to give that power to the these devices.

You need to find out the right combination so the motor turns. There is 36 different combinations and it only works in 6 of them.
When it turns do not fully accelerate the motor before you make the sensors identification angle protocol.

Hello Gonzalo I have a Kelly kbs-x 72v 55amp controller I’m trying to wire up to a cyclone 3000w motor, could you give me a run down on what PIN numbers go with what for throttle, acceleration switch, 12v out? I’m having some trouble figuring this out as I’ve seen different things. I’ve read the manual but i want to make sure, as well as do you think I’ll need the pre charge resistor? Or instead can I use a capacitor parallel with the battery lines into the controller ?Thanks for the help in advance !
Hi Cristian.
- First of all here is where you can download the latest manual: kellycontroller.com/wp-content/uploads/kbs/KellyKBS-XUserManual.pdf
- On pages 10 and 11 you got clear schematics about the connections.
- For the throttle: Pin 20 is ground (usually black cable in throttle) Pin 4 is 5V (usually the red cable in the throttle) and Pin 3 is the signal from the throttle (usually white cable in the throttle but can be other colour)
- For what they call "acceleration switch", I think they refer to a dead's man switch, latter they call it in the manual foot switch. I talk in the video about it. You can use it or not as it can be enabled or not.
- (Pin 11) 12V out, this to use just in case that some sensors may require 12V instead of 5V (Do NOT use it to feed other vehicle systems as it gives very little current)
- With 72V I recommend that you use a resistor precharge system.
- You can add a capacitor at the entrance of the controller if the distance from the battery to the controller is very large. But this will make even more necessary the precharge system.
@@gonzalop.chomon327 for the precharge system how exactly can that be set up do I have to have a contactor? The battery will be in a back pack with a cord about 3 feet long, would that distance be long enough to be able to just use a spark arrest such as a capacitor?
@@cristhianhoyos7863 The precharge system is in order to charge the capacitors that the controller has inside, if you add more capacitors then there is more capacitors to be charged... so more need of a precharge system.
You can buy connectors that have that precharge system incorporated in them, that maybe the easiest solution for you.
here: https: //s.click.aliexpress. com/e/_9fjDxU (without the spaces)
@@gonzalop.chomon327 I couldn’t use that link, but I think I found something similar? It’s a anti spark xt90 would that be what I need ? Bc my battery will be disconnected very often so I’m not sure how I can do a regularity charge system currently I’m using xt90s to from the battery to the controller, if I replace those with anti-spark connections will that work ?

Hello Sir, I am currently working on a 3 wheel project. I am working with a Kelly KLS7212N model driver. I am working with a 3 wheel vehicle of approximately 400 kg.(Gearbox ratio 1:10) The vehicle cannot go uphill without a booster gear and overheats, reaches about 90 degrees Celsius and protects itself from excessive heat. How can I overcome this problem, which parameters should I change?
There is some parameters at the controller that can be tuned in order to reduce the motor temperature.
Between others the main parameter you can tune is: to reduce the overall power, but as you commented, you have power problems.
What makes me think that the problem maybe that the motor is not powerful enough for your application.
Can you give information about the vehicle: Weight, speed you want, aerodynamic coefficient, frontal area, etc.
So it is possible to calculate what is the motor power for your needs.
Gonzalo , i have controler Greentime 84v 1500 w did you know how to program that controler and with wich cable ? problem is angle 60 degree it must be 120 degree If you know you will make me happy :)
Do you have a manual that I can look to?
Post the link if so.
Hey, can I programme the controller to have something as eco mode to consume less power and have speed restricted to +-25km/h and other configuration with full power and switch between them in real time? Something as chinese e-scooters have. Thanks!
Yes, you can have 1, 2 or 3 "speed gears" by a switch.
And you can program the speed for each "gear"
@@gonzalop.chomon327 Yes I finally find out too that it has three speed, but didn't know about custom program to each one, that's great! I have another question which I can't find anywhere. Do you know the main difference between KLS and the "legacy" KBS? KBS is slightly more powerful, 55A/130A, against 50A/120A in KLS. As I understand, the software and functionality is different, but I don't know the details. I want good throttle response and KBS should have torque throttle mode. Thank you again :)
@@thepretiso The main difference is that KBS ones are square wave and KLS are sine wave controllers.
Software is more less the same.
While in the KBS you have 3 modes to choose from (Speed, Speed/Torque and Torque) in the KLS you have direct access to edit the PID numbers.
@@thepretiso At video part 3, you can find how to setup the 1, 2 or 3 speeds switch.
@@gonzalop.chomon327 Oh really? there is no mention on Kelly's site that it's square wave, I thought it is also sinewave. So what do you suggest is best option for e-scooter? I am worry that KLS would lack that acceleration punch from the start, what do you think? Also I think that configuration of KBS is easier. Ill check that part3!
i have a kls it has a tft screen there is no sm4a or rs232 port will i need to go via julet connector (tft screen connector?) hardwire a bt adapter on there?
I suppose that then it is already being programed for a certain vehicle or a motor/battery set.
If it does not have a programing connector then you will need to open it and add it if you want to change parameters.

Hi Jean, this KLS controller models does not have PAS sensor input chanel.
There can be a way to connect a PAS, Torque, Force or similar sensors and made them work, but I do not know how.
@@gonzalop.chomon327 Thank you very much i was lost not to find it.
@@gonzalop.chomon327 I have a torque sensor i will probably try on the accerator chanel
@@jeanterine4712 Let me know if it works and how.
Afaik the only way to really get PAS support on the Kelly ESC is to pair it with a Cycle Analyst v3 display from Grintech. To do that you'll need either (easier way) the grin tech external molded shunt or do a CA hookup to the controller motherboard. Then you setup your pedal assist parameters on the cycle analyst.
The BBSHD has 88 effektive Motorpoles,does it mean i have to write 44 at motor poles,
And which Temp-sensor do i choose when there is a 10K in the BBSHD??? Thank you
The BBSHD motor has 4 poles so it will be 8 for the "Motor Poles" field.
About the thermistor, this controller accepts the KTY84-130 (970 - 1030 Ω) and the KTY83-122 (1000 - 1020 Ω) so I believe that a 10K thermistor will not work for this controller.
@@gonzalop.chomon327 Okay only 8 poles, thank you!
Hi i have another question, my bbshd doesnt finish the identification angle, both LEDs stay on, the error code is 3-4 speed sensor, do you have a ideal what the Problem is..Thanks
@@manuelschilli4912 First, what controller model are you using?
Second, does the motor start?
@@gonzalop.chomon327 kls7212s, no the motor doesnt turn, it Klicks about 7-8 Times when i do the identifikation angle. When i turn the power on the code 3-4 red Lamp comes
WHAT I LEARNED .... you must use the kelly RS232 driver
Yep, you can use that as I did. As well there is a Bluetooth connection device available, but I have not tried it.
@@gonzalop.chomon327 Does anybody know can use normal 5v TTL programmer ? (GND, RX, TX, 5V)
@@garbagej4427 Not sure, but I think that can not be used for this.
Hi Gonzalo, thanks for the tutorials. wondering whether u be making a wiring video as mentioned? ive got a KBS72181AE and the manual reads 'All contactors or circuit breakers in the B+ line must have precharge resistors across their
contacts', but it doesnt seem like you have and im hoping there will video to enlighten this matter with other systems like the regen braking. tqvm for reading
No I have not used any prechager system, that is why you can listen the sparking on the videos. The model used for the video is quite small so it is possible to skip the precharge at cost of replacing connectors or switches occasionally. But for bigger controllers precharge resistor or other system is a must.
You can find info about the regen braking on the following videos:

@@gonzalop.chomon327 hi again Gonzalo. I wired my KBS72181AE like u did and applied very low throttle. The motor turned for a few seconds but then the controller overheated and shut down. After letting some time to cool I tried again but the Led indicated there's too much voltage into the controller. I suspect it could be my wire running from the battery to the pink wire 7 being not the right size and resistance maybe? What's the right awg then? Thanks
@@guumballl Pin 7 is just the "switch on" signal, it does not need any kind of big load cable.
If controller heated up in just a few seconds, something must be done badly.
Check everything with the schematics in the controller manual making sure that all is connected in the right way. And of course make sure that the battery voltage is not over the controller limit (90V for your model)
@@gonzalop.chomon327 the wire to pink is also the source for the controller no? (Beacuse it is running parallel with the battery) . I'm using a fairly thin wire (but is thicker than the pink one) and my battery is 6s anyway so around 22v + only. What else could be the problem?
@@guumballl The current source for the controller are the main red and black cables.
22V is too low for that controller model.
Here is the manual: kellycontroller.com/wp-content/uploads/kbs/KellyKBS-EUserManual.pdf
RTFM :)
Hi, and thanks for the tutorials. So, I have a KLS7212S with 48v/1000w motor and 52v/16ah/30amp battery. What do you reccomend for battery current setting? Also is there a setting to make acceleration faster, the throttle feels so slow at first...then ramps up. Might need fast acceleration for an emergency. Thanks.
If the battery is able to deliver 30A as you described, then set it at 30A (You need to make the calculations to transform it to % )
For more acceleration change the PID numbers. I talk about it at 3rd video.
@@gonzalop.chomon327 oh ok, thanks I will check it out 👍
Συγχαρητήρια για το ωραιο βιντεο, θα ειθελα να θεσω και εγω ενα προβλημα που αντιμετοπειζω με εναν ελεκτη KLS7230N δεν συνδεεται μεσο Bluetooth εχει γραψει τρια σφαλαματα με τα γνωστα μπιπ, (1,3) (3,3) (3,4) τον αποσυνδέω απο το ρευμα και δεν διορθωνη τα σφαλματα και μου γραφει οταν παο για να συνδεθω device is not opened please open device first, καθε βοηθεια θα ειναι πολύτιμη ευχαριστω εκ πρότερων.
The errors that you report are the following:
1-3 Low battery voltage: Charge battery and check battery voltage limits at software.
3-3 Faulty throttle: Check the throttle device and replace if faulty, as well check threshold limits of throttle.
3-4 Problem with hall sensors: Check if hall sensors are ok, Check connections, Select the correct type of sensors, Proceed to make the hall sensor identification angle procedure.
@@gonzalop.chomon327 thanks for the help online ok now we have (3,3) PEDEL ERROR writes it in red .. what we do .. TIPS; HALL GALVANOMETER RATE RANGE 0-1000A.
@@christosxenopanagos2737 The best will be if you can try another kind of throttle.
@@gonzalop.chomon327 ok the throttle works but when the closed one is a little slow to slow down, what else can it do ..
@@christosxenopanagos2737 Sorry, I do not understand your comment can you rephrase it.
Hi my motor reverse speed is very high how to change settings
Hi Kaviraj, Check the second video of settings it is explained there how to change reverse top speed.

@@gonzalop.chomon327 hey thankuu so much because of you I have successfully done the motor programming
@@kaviisworld Good to know :)
@@gonzalop.chomon327 hey also what is that foot switch actually do
Supposed I have motorcycle it has side stand and I turn on foot switch in controller until I remove or I lift up the side stand then only motor can start right
My second point is that cruse control its start automatically after 5 sec its dangerous I want to use switch whenever I want I can turn on and off is it possible
@@kaviisworld The "foot switch" is a safety switch that can be used to make the motor stop or not start if not activated. Like you said in a motorbike can be used at the side stand.
The only way that cruise control activates is automatically after 5 secs. same speed in this controller model.
What are the other controllers you showed in the beginning of the video?
I think one is a KT and the other a Rinsun.
