Program sine wave 18 mosfet controller help

[Andrenav03]

Hey guys I’m new here I was brought here by this question on how to program a my specific controller. I watch a Video on YouTube and tried to email the guy in the video named Barent but the email was not working. On another forum they said that Barent hangs out here so if you read and know him try to send this page to him.

This is a 72v kit from kirbebike 4000w

Anyways I’m trying figure out how to reprogram my sine wave 18 mosfet controller to do regenerative braking. I believe that the hub motor is capable because it is a brushless DC motor and has one gear. I’m not to sure about the battery BMS capable of taking in regen. Also which connector can I plug it in, I’m thinking the display port since it has 5 pins but I’m not sure. And I’ve tried to take out the whole motherboard out but the heat sink in glued on top.

Also which connector can I plug it in

First of all, do you have one of the family of controllers referenced in the video - I don't see that in the pictures? Any manufacturer that wants to can do anything they want, including not include some capability.

The video you linked has chapters. Which chapter did you run into problems at? We don't read minds.

Do you have the cable shown in the video? Did you install the drivers?

The video clearly identifies the connector on the controller to plug the cable into as it is labelled "Program". Do you not have one? The video also shows the wire colors that lead from the controller to that connector. Can you identify it that way if the label is lost?

But all of that depends on you having the controller shown in the video - getting clarity about that is the first question for you to answer.

With crappy torque arms like that, you'll ruin both your motor and your bike frame if you use regenerative braking. Every time you switch between forward and reverse torque, the TA will allow the axle to budge back and forth a little and loosen the axle nuts a little. Eventually it will loosen, the crappy torque arm will be the only thing keeping the axle from spinning, and it will fail under the forces.

I don't know what you're trying to accomplish with regen braking, but using real brakes is a better, easier, more effective, and much more economical solution.

Thank you for taking your time to write this down. I’m in the beginning of learning all of the technical e-bike skills and wish to understand how to program them from scratch. I’m very passionate about e-bikes they are a great tool.

On the controller the display cable does have a 5 pin connection like the video but it is not labeled for program it does have a similar style connection and colors cable. If that my only option I will go ahead and experiment and see if it works.

Here a full size pic of the controller my fault for not posting it. This controller is from Kirbebike 72v kit

Thank you for mentioning that I did pick up a grin technologies regen torque arm from Amazon haven’t installed it yet cause no regen and I’m going put a disc brake sooner or later lol

I love my regen brake and have absolutely no problems with it since several years now. Don't sell your personal opinion as the only truth!

This controller does not look like the one shown in the video. How do you come to the conclusion that this video will apply to this controller?

Ur right im just guessing it would probably be better just to get a new controller that can be programmed I’m looking at the vesc flipsky controller capable to doing regen. I would have to solder on the phase bullet connection onto the controller.

Interesting, I use regen for maybe 90% of my rear wheel braking as it is better and more effective (it dosent matter how much mud or ice or whatever there is on the brake disc) easier (just press a thumb throttle vs. pulling the brake handle) more economical (less brake wear, and I actually get a little energy back)

My point is that whatever trifling bit of energy you recover, whatever maintenance you defer, and whatever disrepair you let your real brakes fall into, anything you save is wasted a hundred times over as soon as you spin your axle.
