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

The 40A Brushless ESC is a high-performance electronic speed controller designed for 2S–4S LiPo batteries and brushless DC motors. Featuring a built-in 5V 3A BEC and pre-installed XT60 connector, it delivers smooth throttle response, reliable motor control, and efficient power management for RC airplanes, drones, boats, cars, and robotics applications.

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
