36V-48V 500W controller can work with hall sensor/not have hall sensor Rated Voltage: 36V/48V Low Voltage : 31V/42V±0.5V Rated Power: 500W Limit Current: 31A 36V-48V 500W controller function 1. battery line 2. electric lock line 3. 3-speed line 4. Cruise speed line 5. high brake line 6. hall line 7.reverse line 8. low brake 9. Cruise speed line 10.self-learning line 11.throttle line 12. instrumentation line 13. Anti-theft power line 14. Anti-theft alarm line 15. motor line .connect the motor line (color to color） . connect the battery line(red:+ , black:-) . connect the controller throttle line, electric lock（if throttle not have electric lock, connect controller electric lock to battery+ ） . connect the hall line(if motor without hall line, don’t need connect) .docking the two self-learning lines, the wheel will forward or reverse. (1.if wheel forward ,Separate the self-learning line. 2.if wheel reverse, Separate the self-learning line. Docking the self-learning line again if wheel forward ,Separate the self-learning line.)
