Yeah, the controller is a mess.. But as I mentioned earlier, I did manage to get the wheel running by changing the controller, so the battery is definitely not 100% stopping that process. It might shut down while riding because of settings, but you should be able to get power out of it.
Did you just Connect the + and - wire From the Battery? What did you do with the other 3 wires that were coming From the Battery?
Hooked up my minimotors controller with a external battery to the Motor and it spins succesfully without the hall sensor wires.

Mine were secured with square screws. I had to use a security bit.
Is it possible that the bms on the battery is locked? when I measure output on + / - I get 0 volt.
The original controller is impossible to "Reverse engineer" it is filled with a silicon gel and to get the board out you have to be superman.
You can charge the original battery with a Xiaomi m365 charger.
Yeah, battery is CAN Protectet... So you have to bypass the BMS by cutting P+ and P- and solder it on B+ and B- on the side of the batterypack

Thank you very much! I bypassed the BMS with your guide and it works!
Minimotors controller with XT60 onto the original battery pack. Using the EY3 display on the handlebars.

No Problem
But watch out for the voltage of the battery! If it drops below 30V you should recharge it.
I want to buy an Ninebot ES4 Dashboard and Controller because the Dashboard should fit and i am able to flash the controller for variable speed and power

Great to see it work. You didn't do anything with the throttle and brake cables? What about the motor? And what W controller are you using and what's the top speed?

I usually charge the battery when it gets below 36 volts max volts with charger is 41,6 volt.
I think I will design and 3D print a cover for the open hole in the steering stem.
I use the finger throttle that is on the EY3 display I removed the original throttle. The sensor on the brake cable I soldered onto the controllers regen braking input. The motor works without problem I ignored the hall sensor wires and wired it directly with the 3 phases onto the controller.
The controller I used is a 36v 30A minimotors controller as found in the speedway mini 4 pro good for 1,3KW peak.
The top speed is 27km/h sadly I want more! The acceleration is around 4-5 sek to 25km/h.
I can tell you that the motor makes a fabulous sound. The best sound I personally ever heard from a e-scooter.

Can somebody make an Hall Sensor Pinout?

I don't know why I can't reset the password of my original account but here are some very useful infos:
To remove the Battery you just have to pull the cord hidden inside the deck
The actual lock is quite simple an has no IC or sensors:
With 5V (or -5V) on the black and red wire of the 4-pin (blue) Julet plug should do the same
