The MAD AMPX 300A 12-24S HV Drone BLDC ESC is a high-voltage electronic speed controller for demanding UAV and drone propulsion systems. It supports 12-24S lithium battery configurations and provides a 300A continuous current rating when suitable heat dissipation conditions are maintained. The ESC supports both CAN digital throttle control and PWM analog throttle input, with priority given to CAN digital control. It also provides CAN communication, RPM signal output, error signal output, online update support and multiple protection functions. The aluminum heatsink structure is designed for thermal management in high-power installations. Before integration, confirm the motor, battery, flight controller, signal wiring, cooling system and propeller load.

High-Voltage Installation Notice
· Confirm that the battery configuration is within the specified 12-24S range before powering the ESC.
· This is a high-current 300A ESC; the power system, connectors, wiring and battery must be selected for the actual load.
· Maintain suitable heat dissipation conditions during operation. Do not install the ESC in an enclosed position without adequate cooling.
· Confirm CAN or PWM signal compatibility with the flight controller before wiring.
· Temperature detection is listed as not supported; external system monitoring may be required where applicable.
· Complete throttle calibration and verify motor rotation, propeller installation and signal wiring before the first powered test.
· Keep clear of rotating propellers and high-voltage wiring during testing and operation.
