About Speed Limiting Connector
This controller does not support setting the speed limit from P08 of the LCD, but this controller has a speed limit connector reserved; plugging this connector means the controller enters the speed limit mode. The speed limit value designed in our lab is 25km/h. But since this controller is a universal controller, the speed limit value is not the same in different motors; some motors have a speed limit of 15 km/h, some motors have a speed limit of 20 km/h, some motors have a speed limit of 18 km/h, and some motors have a speed limit of 27 km/h. This is not a quality problem; this is a normal problem for universal controllers. If you can't accept this problem, don't order.
We must truthfully describe all the functions of the controller, so that you can buy the most suitable controller.

Basic Installation Wiring Reference
1. Controller
2. brushless Motor
3.LCD display
4. PAS sensor
5. throttle
6.dual brake( low level)
This is a basic mounting reference. The picture uses a brushless geared motor with a Hall sensor; this motor is a 6-wire Hall sensor.
If you are using it for an E-scooter hub motor, this controller also supports 5-wire Hall sensors. Please make sure the motor has a Hall sensor because this controller gets the RPM from the Hall sensor as a signal for the LCD speed display. If your motor does not have a Hall sensor, this controller cannot provide RPM data for the LCD.
Do not use for Hall-damaged or Hall-less motors (Hall-less motors have 3-phase wires only). Please do not use for brushed motors; this controller does not support it.
LCD Display Setting Description
1. Press and hold the “+” and “-” buttons at the same time for 3 seconds to enter the setting mode.
LCD Setting Mode Interface Description

P15-16-17-18-19: Functions not yet opened; please ignore; do not set up
Tip:
P08 and P14 settings are not valid for this controller
This controller does not support setting speed limit and current limit from LCD; the controller voltage program starts based on the voltage selected in P03 of the LCD.
We strongly recommend that normal users set only the P03 battery voltage (e.g., 36 selected in P03 represents a 36V battery), the rest of the settings we recommend keeping the default settings to avoid too many settings and lead to parameter confusion, which leads to more problems affecting your experience.
LCD accurate display speed setting method reference
P06: Please set your wheel diameter in inches; for example, if the wheel diameter is 27.5 inches, please set it to 27.5 in P06, and it will be OK.
Then please open your cell phone Google Maps navigation APP to measure the speed. Please ride at high speed and observe the real-time speed shown by the navigation and the real-time speed shown by the LCD. If the speed shown by the LCD is less than the real-time speed shown by the navigation, please reduce the parameter in P07. If the speed displayed by the LCD is higher than the real-time speed displayed by navigation, please increase the parameter in P07.
And so on, until the setting is the same as the real-time speed displayed by navigation, then you can stop setting; that is to say, the speed display matching is completed.
FAQ
Q: Does it support my motor?
A: Brushless Hall motors are supported; 5-wire Hall and 6-wire Hall are OK.
Q: Is my motor brushless?
A: A brushless motor is 3-phase wire (thick wire) + 6 or 5 Hall wires (thin); others are not brushless motors.
Q: Why does the LCD show E07?
A: It's because you installed it for the first time; the controller didn't finish matching. Please plug the self-learning wires to match your motor; then the high-speed drive E07 will disappear.
Q: How to match the motor?
A: Please plug the self-learning wires (the male and female connectors of the two green wires) on the controller after powering on. The motor will be driven. If the motor is driven in the reverse direction, please disconnect it and change the driving direction again. If the motor is driven in the reverse direction, please disconnect it and change the driving direction again. After the motor is driven stably and in the forward direction, please disconnect the self-learning wires and drive the motor at high speed with the throttle to complete the matching.
