1Twoway communication can be through remote control, low voltage alarm function, low voltage and power failure protection. 2Double motors, strong power, high sensitivity, long service life, durable, check the power of the skateboard. 3Lowspeed and hightorques, twoway communication, you can check the power of the skateboard through the remote control, voltage alarm function, undervoltage power failure protection function. 4Electric fourwheel skateboard control system, the performance is more stable than ESC, not easy to burn out. 5Suitable for skateboards, unicycles, balancing scooter, etc. Condition: 100% brand new Item type:ElectricFourWheelSkateboardController Material:Aluminum + plastic Color: As picture shown Controller size: Approx. 10.5x8cm/4.1x3.1inWeight: Approx. 240g Applicable to: Hub Motor Application areas: skateboards, unicycles, balancingscooters Speed: 3000 revolutions of hub motor Drive mode: dual system drive Control method: sinusoid/Rectangula Current: 16A belt Voltage: 42V Top Speed: 35KM/H Protection: overvoltage, undervoltage, overtemperature, locked rotor, CWCCW, Speed regulation function Sensing method: Hall One key forward/reverse direction Carrying weight: 120KG The remote control is built-in battery: lithium battery, battery capacity 200mAH Remote control matching instructions: When the host is on, press the matching remote control button on the motherboard (the button is side to the buzzer) or press and hold the power button for 10 seconds. When the red LED light flashes, the host is waiting for remote matching. Tap the hide button of the remote control (side to the remote control power switch). At this time, the LED lights of the motherboard and the remote control will flash at the same time, and the remote control is matched successfully. Naught power consumption standby: 10 minutes to enter the standby state. Standby power consumption is naught Low voltage buzzer alarm: a total of four alarm sounds, (one beep 40% power) (two beeps 30% power) (three beeps 20% power) (four beeps 10% Power) four beeps will enter under-voltage protection after four beeps, which effectively protects the battery from over-discharge and damage to the battery. The same goes for the remote control low voltage alarm. 1 x Controller 1 x Remote control
