Hello, I have an EV car quite big. 84v 88Ah battery. Enpower MC3336-7240 controller. I have had several issues with the crager lately. I got out of battery once the charger had got completly broken. I got a new charger, but now the car dashboard is giving me a 2 bips error (it comes from the...

What about the rest, the controller keeps the setting for ever?

Why do you say it is not important? If I set the P and C parameters of the kt controller with the display, and after that I disconect the display, but I bypass the V+ and blue wire (control wire) so the Kunteng controller keeps working. Does the Kunteng keeps the setting I did before? Also if...

Thanks! Tha is a good option, but does it exist something similar in china? Regards

Hello, I have been looking around several bike webs and forums. There apear to exist 2 types of controllers, the one with communication protocol to the different display so the can turn on, switch assistance level and more. And at the other hand we have the famos infusion controller, which you...

Thank you very much for your both answers. I understand Fechter answer is more understandable. So the conclusion is that the controller is which limits the output power, if the motor is too small we will need to be careful with the overheating. Regards!!

Hello, need a little help understanding something. What will define the power of your system, biocides the battery, lets first asume suppose you have infinite voltage or amps, ok? Then, If you have a 1000W motor (2000W peak), and you use a 350W controller, will the motor just run at 350W or it...

Thank you very much for your answer!

Hello, I´m considering buy my self a CA v3.0, but I have a few questions, if the controller already has an internal shunt, would not the external added shunt (from CA) just ad a little more resistance to de circuit? Then, at the V3.0 installation manual it say you just have to plug the...

Yes, at least I had a similar situation with achinase brand and they answered me that the controller didn't had that option inside..

What I can tell you about the regenerative breaking is that, not all the controllers that are programable with the C and P parameters has the internal circuit to do the regenerative breaking.

amberwolf, first of all, thanks a lot for your answers. I´m almost an Electronic Engineer, and for one of our courses we are trying to develop a system to reed and interact with the controllers. We now there is some info, but if we didn't know what we were looking for it was impossible to...

Thanks for your answer! I have found that information on the web. What I do not understand is how it work, I should connect the battery + and - to the red and black of course, then it got to the controller + and -, and the throttle signal and speedo signal to the center black wire?, then from...

AHicks, We are working with my partners at the University, for a system table to read and send info to the different controllers. One of the things that has been more difficult for us is to understand how many typs of different controllers are out there, at least the most important. As you...

Hi, I tried to be as specific as possible in the title. This is my problem, I work for an small neighbor and we bought 10 e bikes from a quite professional builder at china. When they sent the sample with bafang hub motor it worked great. Then to make it a little cheaper we decided to use a...
