Description

FAQ

● 60A Continuous Power, 85A Burst – Strong, reliable output for high-thrust builds.

● BLHeli_32 32-Bit Firmware – Smooth throttle and high PWM up to 48kHz.

● 3–6S LiPo Support – Perfect for 5″ racing, freestyle, and heavy-load quads.

● 20×20mm Mounting – Compact and lightweight for tight frame installs.

● Telemetry & Multi-Protocol – Supports DShot, OneShot, MultiShot and provides real-time ESC feedback.

Features

● BLHeli_32 firmware is the third generation of BLHeli firmware, following base BLHeli and BLHeli_S.

● Supports up to 48K PWM frequency, so the response speed is faster and smoother, reducing mid-throttle oscillations.

● Equipped with double-sided lightweight metal armor to avoid hardware damage caused by crashes, and the armor can effectively assist the MOSFET to dissipate heat.

● Double PCB board design, high current circuit, and signal circuit are independent of each other.

● All codes use damped light mode. Damped light does regenerative braking, causing very fast motor retardation, and inherently also causing active freewheeling.

● Supports regular 1-2ms pulse width input, as well as Oneshot125 (125-250us), Oneshot42 (41.7-83.3us) and Multishot (5-25us).

● Dshot signaling is supported at any rate up to at least Dshot1200. The input signal is automatically detected by the ESC upon power-up, No need for throttle calibration.

● All codes use damped light mode. Damped light mode does regenerative braking, causing very fast motor retardation, and inherently also causing active freewheeling.

● Supports beacon functionality, where the ESC will start beeping after a given time of zero throttles. This can be very useful for finding a lost drone.
