I made a cable for VESC Express. I do not know how those connectors on the VESC Express side are called (I do not remember where I found them) but the end on the Bafang connector side can be made out of these parts...

Cheap alternative to VESC Express dongle...

Alright, great news, I think I fixed it. Just soldered a new AD8418WBRMZ chip, and the shortage is gone. Partially assembled the motor and connected the display and turned it on, the Error 30 is gone, the display shows battery level and the 3.3V regulator is not heating now. So it looks like it...

Found another shortage between 3.3v rail and ground. This time in the bottom board. I was thinking the rotary encoder board is bad and detached it but it turned out the phase "U" current sense amplifier AD8418WBRMZ has internal shortage between ground pin and 3.3v Vs pin. Placed order on new...

If anyone has Innotrace X1 controller laying on the table and willing to try to grab firmware and share it with me is how you can do it (I guess it will work only if the STM32 chip does not set in protection mode though. If it is in protection mode I think this way is not going to work. But...

Hello Krasnodar. I need compiled firmware .bin file to repair my Innotrace X1 controller (please see the post above). I am not sure if you saw my email. Can you please send me a compiled binary file (.bin) for my Innotrace X1 controller adjusted for 3000W motor (52V 60A, 14S lithium battery with...

Hello Dedo. Can VESC tool extract .bin fie firmware from the controller? The original STM32 chip on my Innotrace X1 controller is dead (internally shortened 3.3v and ground pins). I guess the FET driver failure destroyed the chip. I soldered new FET driver and STM32 chips and I need binary...

I think my Kindernay VII sounds as loud as yours when it is freewheeling in the air and it feels quite when I ride it.

It does sound noisier than mine or maybe this is just microphone pics the sound this way. Mine is leaking.

Where I can purchase one?

I am looking for the most puncture resistant tire in size 27.5x3.00. I do not care if it is going to be rigid as hell, or heavy as tank (I got 3000W motor so weight is not an issue for me), I also do not care about the threat style, color, bead material etc. All I need is the toughest (and maybe...

Wow, that's not even close to what they draw in the advertisement

The gearhub still works the same.

I do not know which grease is the best for this application. I just know Innotrace offered greasing the motor with red Mobil grease as an upgrade, so I just applied it.

You can build and use custom battery with Yamaha system, or you can purchase an aftermarket battery for Yamaha, or you can rebuild the original Yamaha battery with new cells and new BMS, it was hacked...

Alright, finally the first serious problem with my Bafang m620 and Innotrace X1 3000W controller. After about half a year of riding the motor become extremely loud with grinding sound and maintained free pedaling resistance. I rode it like that another half a year and motor got even worst, it...

The source of the noise might be not only the lack of grease. Inspect the middle gear bearing (the overrun one way bearing) pressed into the larger one gear. The large one middle gear can slide down on that bearing causing the gears rubbing each other making noise (in some cases extremely loud...

I hope they will design such controllers for Bafang m620 and new upcoming m630. I would instantly purchase it.
