40A Brushless Motor ESC Speed Controller with Connector for Drones
The 40A Brushless Motor ESC Speed Controller is designed to provide smooth, responsive, and reliable motor control for RC drones, quadcopters, multi-rotors, and RC airplanes. With support for 2S–3S LiPo batteries and motors drawing up to 40A, this 40A BLDC ESC delivers efficient power management and responsive throttle control for stable flight performance.
Its built-in 5V/2A BEC can supply regulated power to a flight controller and other onboard modules, while the pre-soldered 3.5mm bullet connectors simplify installation. The ESC also features low-voltage cutoff, overheat protection, and throttle signal loss protection for safer operation.
It can be programmed using a compatible programming card or transmitter, making it a practical 40A electronic speed controller for brushless motors in DIY and RC applications.
