[Excellent Performance]: The motor delivers strong climbing ability with low running noise, reducing tire noise. [Scope of Application]: This is a wide-voltage controller compatible with 48V, 60V, 72V, and 84V systems. Maximum current rating is 80A, indicating the controller can withstand up to 80A of current (actual output depends on battery and motor specifications). Suitable for use with brushless motors. [Upgraded Components]: Motor features thicker copper bars, improved inductance accuracy, smoother startup, and enhanced ride comfort. [Precision Craftsmanship]: Professionally manufactured with stable performance, increased shell thickness, and improved heat dissipation for high reliability. Enhanced hill-climbing torque, strengthened power delivery, faster speeds, smoother motor operation, and extended controller lifespan. Color: Silver Material: Aluminum Alloy Package Contents: 1 x 3000W Controller (other items not included) Note: Lighting reflections and display settings may cause slight color variations between the image and the actual item.
