Feature:1. High Performance Chip: The speed brushless controller uses a single chip microcomputer as the main control chip to control and protect the motor and battery of the electric vehicle, so that the electric vehicle drive system works in the best state.2. Multiple Protection: The Hall electronic stepless speed regulation system is adopted, which has protection functions such as undervoltage protection, overcurrent protection, and stall protection to ensure the use and of electric vehicles.3. Characteristic: Brushless controller supports 1. Automatic voltage setting, 2. start without Hall, 3. Automatic identification with Hall or no Hall, 4. Motor short circuit, open circuit, Hall, power protection 5. 32 bit Single chip microcomputer, fast learning and high efficiency.4. Aluminum Alloy Housing: The outer casing of the motor controller is made of aluminum alloy material, and the groove design can protect the internal circuit, facilitate heat dissipation, and avoid thermal overload.5. Line Function: The brushless controller has multiple lines, including anti‑theft function line, reverse line, 3 speed line, line, instrument line and high and low brake lines for more choices.How to Use:1. Connect the upper three thicker blue wires, green wires, and yellow wires to the motor blue wires, green wires, and yellow wires, and then connect the controller Hall wires to the motor Hall wires.2. Then connect the two thicker red and black wires of the controller to the power supply, the red wire is connected to th
