48V-84V 2000W controller brushless can work with hall sensor/not have hall sensor Name: Intelligent dual-mode brushless controller Rated Voltage: 48V-84V Low Voltage : 41V Rated Power: 2000W Limit Current: 45A Number of brushless controller tube：18 Weight：1kg Size：20*10*7cm 48V-84V 2000W controller function 1. Jog 3-speed 4-speed (generally not used) 2. 3-speed 3. throttle 4. low brake 5. cruise 6. reverse 7. Instrument line (display driving speed, power, kilometer mileage) 8. Self-learning line 9. High brake (the brake lever has 2 wires, the black is connected to the high brake, and the red is connected to the controller converter 12V, the high brake may not be used) 10. hall 11. First-line general LCD instrument line 12. Anti-theft signal 13. Anti-theft power supply 14. Electric door lock (connect to throttle electric lock, if throttle not have electric lock, connect to battery +) 15. Power cord 16. motor line 1.connect the motor line (color to color） 2. connect the battery line(red:+ , black:-) 3. connect the controller throttle line, electric lock（if throttle not have electric lock, connect controller electric lock to battery+ ） 4. connect the hall line(if motor without hall line, don’t need connect) 5.docking the two self-learning lines, the wheel will forward or reverse. (A1.if wheel forward ,Separate the self-learning line. A2.if wheel reverse, Separate the self-learning line. Docking the self-learning line again if wheel forward ,Separate the self-learning line.) 6.other functions can be connected as needed.
