40A Brushless ESC 2-4S Speed Controller 5V 3A BEC with XT60 Plug

The 40A Brushless ESC 2–4S Speed Controller is a high-efficiency electronic speed controller designed to deliver precise and reliable control for sensorless brushless DC (BLDC) motors. Supporting 2S to 4S LiPo battery packs, it provides a continuous output current of 40A, making it suitable for a wide range of RC aircraft, drones, helicopters, boats, RC cars, and robotics applications.

This ESC features a built-in 5V 3A Battery Eliminator Circuit (BEC), allowing it to power receivers, servos, and flight controllers directly from the main battery without requiring an additional power supply. The pre-installed XT60 connector ensures quick, secure, and low-resistance battery connections for improved convenience and performance.

Designed with high-efficiency MOSFET technology, the ESC offers smooth throttle response, fast motor startup, and stable operation while minimizing heat generation. Integrated protection function
