T-Motor F55A Pro II 55A 3-6s ESC

Overview:
The T-Motor F55A Pro II is a high-performance 4-in-1 ESC designed for demanding FPV freestyle, racing and cinematic builds. Supporting 3-6S LiPo batteries and delivering 55A continuous current per channel, it provides the power handling required for modern high-output motors while maintaining a compact 30.5x30.5mm mounting format.

An updated version of the original F55A, the Pro II features a redesigned heatsink, integrated status LED and an upgraded 10V BEC output. The 32-bit BLHeli_32 architecture supports advanced ESC functionality and fast throttle response, while compatibility with several DSHOT protocols allows seamless integration with modern flight controllers.

Designed for pilots pushing their quad to the limits, the F55A Pro II delivers the current handling required for demanding 5 inch freestyle and racing setups.

Features:
- High-performance 32-bit microprocessor operating at up to 48MHz.
- BLHeli_32 firmware for advanced ESC performance and configuration.
- Damped Light mode with regenerative braking and active freewheeling.
- Motor desync protection with adjustable tuning parameters.
- Supports PWM, OneShot125, OneShot42 and Multishot protocols.
- Supports DShot digital protocols up to DShot1200.
- Automatic input signal detection during power-up.
- Integrated beacon mode to help locate a lost aircraft.
- Built-in 5V BEC for powering flight controllers, VTXs, cameras and LEDs.
- Adjustable startup power for optimising motor start-up performance and low-RPM operation.
- Adjustable motor timing from 0° to 30° to suit different motor types and applications.
- Supports ESC parameter configuration directly from the transmitter.
- Adjustable minimum throttle, maximum throttle and centre throttle settings.
- Configurable over-temperature protection to help prevent ESC damage.
- Low RPM Power Protection protects against motor desynchronisation during low-RPM operation.
- Brake on Stop- optional automatic motor braking when throttle is reduced to zero.
- Adjustable low-voltage protection from 2.5V to 4.0V per cell, or can be disabled.
- Adjustable current limiting to protect the ESC and power system from excessive current draw.
