36V/48V 750W Waterproof Brushless DC Motor Controller - Electric Bike Speed Controller for E-Bikes, Scooters & DIY Projects | Perfect for Commuting, Off-Road & Urban Riding

Feature: 1. Heat Dissipation Function: The controller shell is made of high quality aluminum alloy with design. Due to its good heat dissipation function, it can protect the internal circuit and avoid thermal overload. 2. Provide Stable Speed: The brushless motor sine controller can provide stable speed and sensitive braking and direction change control, providing you a good using experience. 3. Waterproof Connectors: Fully waterproof connectors ensure maximum durability in any weather conditions. High performance wires and waterproof interfaces are durable, ensuring low failure rates for long term use.
