Key features and benefits

• LiPo 3S battery support: Optimized for safe and efficient operation with 3S power sources (11.1 Volts), ensuring stable performance under typical model loads.
• Continuous and burst current: Provides a continuous current of 20 A, with the ability to withstand short-term peak loads required during maneuvers and startup.
• Integrated BEC: The built-in switching BEC provides stable voltage and the necessary current to power the receiver and servos without additional modules.
• Dimensions and weight: Compact dimensions of approximately 55 mm x 28 mm x 8 mm make the controller easy to install in confined model compartments; its low weight helps keep the overall aircraft weight down.
• Protection and programmable functions: Includes built-in overvoltage and overheating protection, as well as support for braking and soft start modes, significantly enhancing safety and control during flight.

This ESC is suitable for those building or maintaining mid-class drones who need a reliable solution with an integrated BEC and protections. The T-Motor AT 20A 3S model provides confident control over motors, ensuring the necessary startup characteristics and stable power delivery to the control system and peripherals.

In technical documentation and when selecting components, pay attention to the correct connection of the LiPo 3S power source, polarity, and recommended current parameters for your motor and propellers. Thanks to its compact size and functional protections, the controller easily integrates into both ready-made kits and custom builds.
