ELECTROCRAZE 20D-BD Dual Channel 20A Brushed Motor Controller

The ELECTROCRAZE 20D-BD Dual Channel 20A Brushed Motor Controller is a high-performance Electronic Speed Controller (ESC) designed for controlling two brushed DC motors independently. Built for robotics, RC vehicles, automation systems, and DIY engineering projects, it delivers 20A continuous current per channel with a 45A peak current (5–10 seconds) for demanding applications. It supports 3S–4S LiPo batteries (11–17V) and includes an integrated 5V BEC (Battery Eliminator Circuit) to power receivers or control electronics without requiring an additional power source. Safety features such as signal-loss protection, braking, and reverse operation make it a reliable choice for professional and hobby robotics applications.
