Here are the key Features of this ESC:

Current Rating: The ESC has a continuous current rating of 55A. This indicates that each ESC on the 4-in-1 board is capable of handling a continuous current flow of up to 55 amps. Higher current ratings are often preferred for freestyle drones that may have more aggressive flight maneuvers and higher power requirements.

BLHeli_S Firmware: The ESC uses the BLHeli_S firmware, a popular choice for ESCs in the drone and RC community. BLHeli_S firmware provides features such as motor braking, active freewheeling, and smooth throttle response. Dshot600 is a digital communication protocol used between the flight controller and the ESC.

Voltage Input Range: The ESC is designed to handle a voltage input range of 3-6S LiPo batteries. This makes it compatible with a variety of battery configurations, from 3 to 6 cells in series.

Brushless Motor Support: The ESC is specifically designed for use with brushless motors commonly used in multirotor aircraft. Brushless motors offer higher efficiency and better performance compared to brushed motors.

4-in-1 Design: The "4-in-1" design means that four individual ESCs are integrated into a single board. This configuration simplifies wiring, reduces the overall weight, and streamlines the installation process in a drone.
