BLHeli_32 45A 4-in-1 ESC — 30×30mm FPV Quad Stack

A 4-in-1 electronic speed controller integrates all four ESCs onto a single board, eliminating individual motor wire runs and reducing stack height and weight compared to four discrete ESCs. The BLHeli_32 firmware running on a 32-bit ARM processor unlocks the full feature set that makes modern FPV possible: bidirectional DSHOT for RPM telemetry, RPM filtering, motor desync protection, and real-time ESC telemetry.

Rated at 45A continuous per channel (burst 60A), this ESC handles 5-inch freestyle and light racing builds on both 4S and 6S without thermal throttling. Current sensor provides real-time current draw for battery capacity tracking in the OSD. Compatible with all DSHOT, Multishot, and PWM flight controllers.
