OK thanks a lot. I have read the relevant threads and found out that the best was is to change the LM317 and the resistore with a V7815W. But it is not so easy to order in germany. What can i also use? Every dc dc converter with an Output of 15V?

Good morning, i have test it yesterday with opened controller. After a short ride of 1km the big restistor gets warm. Round about 50°C The Mosfets were cool.Round about 28°C. So I think the problem at a longer rides came from the resistor. What is it for? I have only pas, throttle, brake and...

It goes out. And after 5 minutes i can restart it again. Not sure why, but it happend like this. I must test what get hot. At the last ride the housing was closed, so i had no possibility to chek where the heat came from. About the motor specific angle. I changed it several times over the...

I know that the controller is to small for my motor. but i got this motor for free and don't need the full power. That is the reason of the small controller. Do you mean that the regenerative braking is the reason of the high temperatur. But i'm also use that feature with the stock controller...

Thanks for your answer. But it gets so hot, that is swith off automaticly. So it is not possible to use it. I can try to reduce the current from 100 to 80? Best regards Sascha

Hello and good morning. i have a little problem and i have no idea why it is so. At the first to the facts: - I have a rear hub motor with 1000W. - Pas Throttle and BrakeSwitch - KT 36/48 SVPRD-HRD01 With the standard Kunteng KT Stock Controller, i can ride my bike without any problems. Not...

Must I reduce gain P and I at the same time and the same value? So when I go to 0.01 the other value must be 0.04? And again, do you have any idea why assist level 0 at the lcd3 corresponds to level 1 at the java tool? Greeting from the lovely Germany ;-). Sascha

I have tested the new display.c file with the values 1-10with sucess. So for me it is working. But maybe your Display has an other cecksum value? You can try to change the values 1-10 to 11-20. It's working for me,too. I have decrease the undervoltige protection to 50 and now it stop cogging...

I can solve the problem with the help from stancecoke in the german forum. The Problem was the checksum from the UART messages to the display You must edit the display.c. At the moment i don't know which value ist the correct one, because i change yesterday all 5 to 5 new at one step. One of...

@j bjork Thanks for your answer. I found your setting 2 pages before. You write there, that you have no function with the KT-LCD3. Did you solve this problem? I have the same issue. Only the voltages is displayed. No Battery Symbol,.. and the assistant value has no effect. @apple2 Are you...

Hello at all, i have a simmular setup with a 1000W 48V 28inch rear hub and the KT36/48 6 FET 10A Controller with the custom firrmware. At the moment i have only a KT-LCD3 Display, but i habe ordered a bluetooth modul and a 5V DC voltage regulators. Can you send me your config ini from the java...
