Someone mentioned EY3 display and 36v 30A minimotors controller.
https://www.scootertalk.org/forum/viewt ... 977#p54977

I found the display kit but I am struggling to find the correct controller.
Here's one example that can be 36v 30A but I don't know if SM plug type needed? And then how to convert controllers display 5 wires to 6 wire plug on display?

I'm in the same boat as you, hopefully someone who knows can help us out soon enough. The eye3 display is quite pricey though I can imagine there being something cheaper out there. Wish I had more time to research this some more.

The motor seems to have some weird 11-pin plug 3 phase wire plus 8 for hall effects and prob temp sensors, but they are all color coded, after removing the insulation.
My question now is: is the color coding correct/the same as any standard motor?

-thank you

As I see this thread is still alive so hi everyone.
I found a mudguard battery next to a bus stop, probably some vandals left it there, anyways, I wanna make a powerbank out of it and as some have mentioned, there's 0volts on the power pins, and I read here it's Can protected. Now I don't know a lot about these communication protocols neither about e scooters so my question is does anyone know how to communicate with the battery? Maybe it's some standard stuff and I only need some 3 dollar pcb off AliExpress , but I fear It's proprietary and I need an entire scooter. I don't wanna solder the cable onto the battery pins directly because then I need an undervoltage circuit or similar and if I only need some cheap can to usb adapter that I rather buy that and use the inbuilt protection and be able to swap original batteries now that I know how to get more ;)
