This high-performance 40A Brushless ESC (Electronic Speed Controller) is designed to deliver smooth and precise throttle response for brushless motors in RC airplanes, helicopters, quadcopters, and multirotors. Compatible with 2S to 4S LiPo battery packs, it features an integrated 5V/3A Battery Eliminator Circuit (BEC) to reliably power your flight controller, receiver, and servo motors without needing a separate battery source.
40A Brushless ESC Electronic Speed Controller with 5V/3A BEC
Overview
The 40A Brushless Electronic Speed Controller (ESC) is engineered to deliver smooth, linear, and highly responsive throttle control for brushless motors. Optimized for RC aircraft, fixed-wing airplanes, quadcopters, helicopters, and custom robotics platforms, this speed controller acts as the vital power management hub between your flight hardware and your battery pack. It is designed to sustain demanding continuous electrical loads while keeping throttle latency to an absolute minimum.
Integrated Battery Eliminator Circuit (BEC)
Eliminating the extra weight and clutter of a secondary onboard battery pack, this ESC features an integrated 5V/3A linear Battery Eliminator Circuit (BEC). This built-in hardware regulator steps down the massive voltage of your primary power cells to provide a clean, constant 5V feed directly down the signal line. It offers more than enough current to simultaneously run your flight controllers, radio receivers, telemetry modules, and high-torque control servos.
Robust Safety and Multi-Cell Protection
Encased in a durable, heat-shrink insulation jacket, the internal PCB uses high-efficiency MOSFETs to maximize power output and minimize heat generation. To safeguard your model against catastrophic failure, the ESC features a suite of automatic protection parameters:
- Low-Voltage Cutoff (LVC): Automatically lowers power output when the connected battery drops near critical levels to protect your LiPo cells from deep discharge.
- Over-Heat Protection: Throttles or halts power output if internal temperatures exceed safe operating limits.
- Throttle Signal Loss Protection: Instantly cuts power to the motor if the radio signal drops out, preventing hazardous runaway conditions.
