Hi!
I've bought that motor, searched weeks to find info about controller and etc, then teared apart, found the controller part number and searched on that, found that it is the controller of Lexmoto Cypher.
It turned out it is a rebranded motor: Lexmoto Cypher
It has a 1500W controller and 2000W QSmotor, not what M0tr0n seays in spec, it is not 3.7kW and not Bosch motor.

This method also worked on mine, everything is the same:

They changed only some colors and the balance charge port to M25, here this port is used, having CAN H and CAN L signals to be able to start charging or draining.
So not happy, I cannot charge it with my custom low amps slow charge solar panels

it needs CAN signals to charge and communicate somehow..

So I could test de-restricted based on Cypher instructions, went until about 50-55kmph in ECO and 69kmph in POWER mode, but I was out of road so it could go above 70kmph a bit.
