1The sinusoid solution makes it more stable than ESC and not easy to burn out. 2The single driver design is composed of highquality chips and electronic components, which can provide excellent and stable performance. 3The sturdy structure of the motherboard can greatly extend the service life. 4Low speed and high torques. 5Twoway communication, you can check the power of the skateboard through the remote control. 6Multiple protections, with low-voltage alarm function, under-voltage and power-off protection. Condition: 100% brand new Item type:SingleDriveDrive Set Material: plastic Color: As picture shown Weight: Approx. 172g Rated voltage: 24V Product Category: Pedal Scooter Remote control battery: built-in lithium battery Capacity: 200mAh Applicable people: universal Current: 8A-12A Speed: 3000rpm Induction mode: for Hall Maximum load capacity: 120kg Large size of motherboard: Approx. 78x58mm/3.1x2.3in Small size of motherboard: Approx. 35x20mm/1.4x0.8in Functional product description: 1. Four gears, 1 low speed. 2 medium speed. 3 high speed. 4 player mode 2.EBS electronic brake (the battery will be charged when the brake is sliding downhill. The maximum valvecurrent is 10A) 3. One key to turn forward/reverse direction 4. Wireless 2.4G remote control transmission control. 20 frequency points. Automatic frequency hopping anti-collision 5. Maximum valvecurrent 40A 6. Controller features: low Speed and high torques 7. Maximum Speed: 3000 revolutions of hub motor (positive Xuanbo), 7500 revolutions of belt motor (rectangula). 8. One-key switch. Long press for 10 seconds to enter the paired remote control state (refer to item 20). The button LED working indicator is the connection status indicator with the remote control (flashing when the connection is successful, and the connection is unsuccessful, long on) 9. Hub motor. Choose by yourself without feeling or feeling (common for control boards) 10. Control method: sinusoid/rectangula 11. Equipped with motor. Hub motor 70.83.90. Motor. 80KV / model airplane motor 270KV or less, the effect is better 12. Three modes of control, four-wheel brushless controller integrated Two modes: Hall sinusoid (automatic learning motor) The second mode: Hallless rectangula (compatible with 99% motors on the market including non-inductive model airplane motors) The third mode: there is a hall sinusoid fault repair mode (when one of the three halls of the motor is broken, it will repair and simulate the failed hall after the program is checked. If the two halls of the motor are broken, the program will automatically switch to No Hall rectangula mode) 13. The program is repaired by Hall. If the Hall is broken, one can operate normally/rectangula without affecting normal use. 14. Motor wire short-circuit protection. Motor wire off protection / stall protection / high valve current protection / battery under voltage protection / over current / over voltage / overload current limit protection. 15.
