Ultra-quiet, motor torque ripple is minimized to achieve no noise, no vibration and comfortableThe controller has high conversion efficiency,which can effectively reduce controller temperature rise and extend battery life.Fit For: Electric Motorcycle/E-bike/Scooter/Electric Bicycle/Balance SkateboardSpecification:Type:DC Motor/Speed ControllerVoltage:DC 36VRated Power:350WUndervoltage:30VCurrent-Limiting:8.8AInstruction:Battery display:33v-36v The first light is long36v-37v one or two lights long bright37v-38.5v one or two lights long bright38.5v or more, one, two, three, four lightsLow 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 push the throttle again to release the cruise control and enter the manual mode.Speed: The low speed is 152km/h; the high speed is 25km/h (maximum)Note:Load has a certain effect on speed.Automatic shutdown: Automatically shut down 10 minutes after no operation.Colour:Black+silverMaterial:Metal + plastic1E communication failure (instrument blue line receiving)2E motor and controller Hall failure.

If you use your own brake handle, you need to adjust the order of his own three wires separately!Package Contents:1 * Controller1 * Dashboard1 * Accelerator1 * Headlight1 * Taillight1 * connecting wireOnly the above package content, other products are not included.Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing.
