Features1Dual Drive Controller: Connecting the main and auxiliary motors, a set of control system can control two motors at the same time to realize various functions, such as braking, reversing, speed regulation and various functions of the instrument. 2Material: Using of high quality aluminum and ABS materials, the motor brushless controller lcd display has workmanship to ensure good toughness and waterproof performance, provide better protection for the internal circuit, making it more durable. 3Stable, Quiet, Sensitive: Using brushless motor controller, the controller works stablely and quietly, sensitive to the working state of the bicycle. 4Widely Used: The brushless motor controller kit is easy to install and use and with high performance. suitable for 22.5mm / 0.9in handlebars. With thumb throttle valve to adjust the speed, it is very suitable for electric bicycles, scooters, etc. 5LCD Display Meter: The LCD display can clearly display status and data, and the backlight allows you to see the screen clearly in a dim environment. The buttons are quick to operate and easy to use.SpecificationItem Type: Motor Brushless Controller LCD DisplayMaterial: Aluminum Alloy + ABSProduct Color: As Pictures Shown Controller Box Length: 18cm / 7.1inController Box Width: 8.5cm / 3.3inController Box Height: 4.5cm / 1.8inProduct Weight: Approx. 1570g / 55.4ozPower: 1000WCurrent Limit: 38ABrief introduction to the working principle and status of the dual drive controller:The dual drive controller instrument kit uses the same set of brake levers, handles, reverse switches, and LCD instruments to connect to the main controller. The main and sub controllers are simultaneously connected to the dual drive signal exchange socket of the same battery power main controller and other sub controllers. The dual drive signal interactive sockets of the controller are connected to each other, and then the main controller and the sub controller are respectively connected to their respective motors. After the meter is turned on, it will identify the phase of the motor, the forward and reverse direction of rotation and the battery type through the intelligent identification line. After disconnecting the identification line, the entire system can operate normally, and at the same time control the two motors to run at the same speed synchronously, brake, reverse, etc. at the same time.Package List2 x Controller1 xLCDDisplayMeter1 x Manual
