Features： 1、Dual Drive Controller: Connected to the main and auxiliary motors, one control system controls two motors at the same time to realize various functions such as braking, reversing, speed regulation and instrumentation. 2、Waterproof Protection: The LCD instrument controller is made of aluminum and ABS materials, ensuring good toughness and waterproof performance, and providing better protection for the internal circuit. 3、Brushless Motor Controller: The brushless motor controller is adopted for dual drive electric bike instrument controller, which is stable and quiet, and is sensitive to the working state of the bicycle. 4、Easy to Install: Controller is suitable for 22.5mm handlebars, with thumb throttle to adjust the speed, very suitable for electric bicycles and electric scooters, with good performance and durability. 5、LCD Display: It can clearly display status and data. The backlight allows you to see the screen clearly in a dim environment. The buttons are quick to operate and easy to use. Specification： Item Type: Instrument Controller Material: Aluminum Alloy + ABS Controller Box Size: Approx. 11.5 x 8.5 x 4.5cm / 4.52 x 3.34 x 1.77in Voltage: 36V/48V Universal Power: 450W Current Limit: 23A 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, turning handles, and reverse switches. The LCD instrument is connected to the main controller, and the main and sub-controllers are connected to the dual-drive signal exchange socket of the same battery power main controller and other sub-controllers at the same time. The dual-drive signal interactive socket of the controller is docked and plugged, and then the main controller and the sub-controller are connected to their respective motors. After the identification line is opened, the entire system can operate normally, and at the same time, the two motors are controlled to run at the same speed, and brake and reverse at the same time, etc. Package List： 2 x Controller 1 x Instrument 1 x Manual
