Generic BLHeliS 15A 2-4S 4-in-1 Brushless ESC 20x20mm

This 15A 4-in-1 Electronic Speed Controller (ESC) provides a streamlined power solution for compact FPV drone builds. Engineered with a BusyBee2 MCU and running improved BLHeli_S firmware, it delivers precise and responsive motor control critical for agile flight maneuvers. Its compact design integrates four individual ESCs onto a single board, simplifying wiring and reducing overall weight and footprint within the airframe. The robust construction ensures reliable performance under demanding flight conditions, with efficient thermal management designed for its 15A continuous current rating.

The ESC’s advanced architecture supports a broad range of digital and analog communication protocols, including DSHOT, Oneshot125, Oneshot42, and Multishot, ensuring compatibility with various flight controllers and optimal signal integrity. Operating on a 2-4S LiPo input voltage, it’s suitable for micro and lightweight FPV quadcopters requiring efficient power delivery. The synchronous rectification technology with damped light enhances efficiency and provides active braking capabilities, offering superior control over motor deceleration for sharper turns and more precise flight adjustments. This integrated design optimizes space and simplifies the build process for demanding FPV pilots.
