Ultra-low noise, the motor's torque ripple is minimized to achieve no noise, no vibration, and comfortable. The controller has high conversion efficiency, which can effectively reduce the temperature rise of the controller and extend battery life. Suitable for: Electric motorcycle/Electric bicycle/Scooter/Electric bicycle/Balance board Specification: Type: DC motor/Speed controller Voltage: DC 36V Rated power: 350W Undervoltage: 30V Current limit: 8.8A Instruction: Battery display: 33v-36v The first light is on for a long time 36v-37v one or two lights are on for a long time 37v-38.5v one or two lights are on for a long time 38.5v or more, one, two, three, four lights Low voltage alarm: The first light flashes when the battery is 33V, and the buzzer sounds 6 times. Low voltage alarm speed mode: The speed limit is about 15km/h. When the power returns to 37V, the throttle must return to the initial position to release the low voltage and return to normal operation. Constant speed cruise: The speed is stable for about 6 seconds to automatically start the cruise control after the cruise is fixed, the throttle can be released; press the brake or press the throttle again to release the cruise control and enter manual mode. Speed: Low speed is 152km/h; high speed is 25km/h (maximum) Note: Load has a certain effect on speed. Automatic shutdown: Automatically shuts down 10 minutes after no operation. Color: Black+silver Material: Metal + plastic 1E communication failure (the blue line of the instrument receives) 2E motor and controller Hall failure. Control failure (right throttle failure) controller drive and motor Hall failure 5E undervoltage failure 6E Motor phase loss To adjust the sequence, the yellow and blue lines are reversed 7E communication failure (sent by the green line of the meter) 8E Other controller failures 9E brake handle failure (left electric brake failure) The brake handle has three function wires, and there are 9 types of arrangement sequences, and the arrangement order must be the same as that of the controller to be used. If you use your own brake handle, you need to adjust the order of his own three wires separately!
