Re: Kunteng Controller and compatible torque sensor

It definitely make more sense using the throttle signal wire !

But what is a pad x4 ?

Re: Kunteng Controller and compatible torque sensor

I don't understand the wiring. On my KT controller input I have : - 1 red wire : +5V - 1 black wire : GND - 1 white wire : PAS signal On the other side, on the e-rider or sempu, I have 4 wires : - 1 red wire : +8-12V - 1 black wire : GND - 1 white wire : torque signal - 1 green wire : speed signal T...

Kunteng Controller and compatible torque sensor

Hi, I have a nice Kunteng controller but I'm struggling with the pedal assist. I first bought a KT-V12L but as described by many people the feeling is not really good. https://fr.aliexpress.com/item/32866352633.html I would like to move on a real torque sensor like the sempu T4. https://fr.aliexpres...

Re: Kunteng Controller Throttle Voltage ?

I mesure PAS and brake positive voltage and I get more 4,2 or 4,6 V ...

Is there any way (potentiometer, resistance, ...) to tune this to get a real + 5 V ?

Re: Kunteng Controller Dealer

It sounds good ! Thank you for your answer :) The bafang B310 has an internal speed sensor but also has a kind of freewheel. So I guess that when the motor is not running the speed display will be zero even if the bike is moving :( That's why I'd like to had a speed sensor. https://www.ebikes.ca/pro...

Re: Kunteng Controller Dealer

Thanks you confirm my doubt. I askedfor the controller datasheet. I'll let you know the answer.

As I said really difficult to know exactly what I'm buy when yoou look for a 1000w sine wave KT controller...

Re: Kunteng Controller Dealer

My findings sent me to this KT48SVPRL controller : https://www.aliexpress.com/item/E-BIKE-1000W-1500W-Electric-bicycle-Brushless-controller/32819334542.html But I'm still a little confused. There is no speed sensor wire :? Do you think that it's just the wire that is missing or that this controller ...

Kunteng Controller Dealer

Hi everyone, I'm looking to build an ebike based on a Bafang G310. According to another excellent topic about this motor it should handle : - 37A max phase current (40 Nm) - 15A max rated current I'd like to go with KT due to the amazing custom possibilities offered by this controller and the good q...

And this one ? https://www.mouser.fr/datasheet/2/196/irf1404zpbf-1226960.pdf Just to evaluate the max potential gain with a MOSFET upgrade without considering the eventual downside effects of the mod what is the rule of the thumb between the max rated current of the MOSFET on the datasheet and the m...

Re: Upgrading FETs in KT Controller

So does it work ? I'm interested in the same mod.

By the way looking on mouser.de I don't understand how MOSFET with a lower Rds have the same Id :confused:

Re: KT motor controllers -- Flexible OpenSource firmware for BMSBattery S/Kunteng KT motor controllers (0.25kW up to 5kW

Hi Folks, I'm very interested in the KT controller specially if it can support the Bafang SW102 display device (also have G310 rear hub motor). https://www.amazon.com/BAFANG-Display-Available-Electric-Bicycle/dp/B07MW261M8/ref=sr_1_11?keywords=bafang+display&qid=1551420497&s=gateway&sr=8-11 Does som...

Re: Bafang SW102 Bluetooth LCD - OpenSource firmware and mobile app

Hi folks,

Very interested in the SW102 project.

I have a G310 bafang rear hub motor.

I'd like to go with the SW102 display but I can't find any controller to go with that.

Would KT controller work with the SW102? Any other idea ?

Thanks for help :)
