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 List2 x Controller1 x LCD Display2 x Handlebar1 x Manual
