It is designed for 8.5-inch scooters equipped with a similar 36V 350W controller, such as the VFLY10. It is often used as a replacement for broken M365-style controllers.
After plugging all terminals together securely, set up the configuration. Because the V2.0 includes automatic motor self-learning logic, it is highly recommended to suspend the drive wheel in the air during the initial power-up. This allows the controller to map out the proper rotational directions and phase alignments cleanly. Is the V2.0 Upgrade Worth It?
Periodically check the stem bolts and folding latch with an Allen wrench, as vibrations from riding can loosen them over time. USER MANUAL – EN IN 24175 E-scooter W-TEC Lambreto Max
Some technicians note that the MOSFET selection and heat dissipation are inadequate for modified setups (e.g., 72V or 1500W configurations), leading to premature failure if pushed beyond its 15A limit. Resetting:
Switch between using the adapter ring or the camera dial via the toggle switch on the adapter body. kcq-yb-hfz-pro-v2.0

While it looks like a Xiaomi controller, users often find it as a standalone replacement kit on sites like AliExpress Display Integration:
Since EF lenses are made for 35mm sensors, some may show dark corners on the larger GFX sensor. Use the "35mm Format Mode" in the GFX menu if needed. 0;2a; 0;7a;0;a5; 💡 Pro Tips for Best Performance 0;16; 0;145;0;4b1; Because the V2
The display board is shaped to fit standard M365-style handlebar stems, making it a "drop-in" fit for various generic Alibaba-sourced scooter frames. Interfacing:
💡 If your scooter suddenly shuts off under load despite having a full battery, it is likely the Low Voltage Protection (30.5V) kicking in due to "voltage sag" in an aging battery.
