Re: Problem with Kunteng Controller / EggriderV2 / Bafang Speedsensor

Problem solved. I changed P3 from "Speed control / PAS Gear Ration" to "Torque / Max power" and then I was able get the speed indication on the EggriderV2 ! Still don't understand why but if it can help some Eggrider/Kunteng owner, it's a solution that worked for me :) By the way thanks for your sup...

Re: Problem with Kunteng Controller / EggriderV2 / Bafang Speedsensor

Sure here are more details : diagram.jpg The problem might come from the controller. I spied the Tx wire from the controller to the display and bit 3 and bit 4 are empty when P2 is not equal to zero. It is consistent with the fact that I never had any speed display with the external or the internal ...

Re: Problem with Kunteng Controller / EggriderV2 / Bafang Speedsensor

I'm removing the speedo sensor from the G310 from GRIN for 2 reasons : - I want to get the speed of the bike when the motor is off (DH for example) - I want to add a temp sensor to monitor the motor temperature as described here by Justin (https://endless-sphere.com/forums/viewtopic.php?f=2&t=92124&...

Problem with Kunteng Controller / EggriderV2 / Bafang Speedsensor

Hi everyone, I'm struggling with an annoying problem and I'll explain it to you to see if anyone have a solution. I'm equipped with : - Bafang G310 from GRIN (great motor by the way!), - EggriderV2 display - Kunteng Controller (12 MOSFETS, 48V sinwave). I'm adding a Bafang speed sensor to be able to...

5v source on Kunteng controller

Hi,

I'm looking for a 5V source in a kunteng controller to power an arduino pro micro.

What is the best place which can provide amp : throttle, PAS , something else ?

Looking for a 60V controller

Hi, I already have a 48V 1kw Kunteng controller. I'd like to upgrade my 13s battery to a 14s battery. The voltage will go up to 58.8V at full charge and I'm not sure that my controller will handle it, can you confirme that ? On the other hand, I'm looking for a 60V controller compatible with Eggride...

I wanna bring this up once again: Any ideas or experience making a resistor-pot mod for changing the output Current ?? like the output voltage mod, just for current. The reason for it would be to make a slow and fast charging switch to the Eaton greets Notger Totally agree with that. It's a really ...

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...
