MAD AMPX 260A (5-18S) Drone ESC

The MAD AMPX 260A (5–18S) Drone ESC is a high-performance Electronic Speed Controller designed for demanding drone propulsion systems. It supports a wide input voltage range of 5–18S (16V–60V), delivers a continuous current of 260A, and can handle up to 300A peak current. Equipped with advanced 32-bit processors and multiple safety protection features, this ESC combines efficiency and reliability—ideal for heavy-lift multicopters, UAVs, and other high-power RC applications requiring robust performance and redundancy.

1. Key Features

1. Wide Voltage Input

   • Supports 5–18S LiPo (16V–60V) to meet high-voltage power supply requirements.
   • Continuous current of 260A and peak current of 300A provide ample power for heavy-lift drones or high-speed aircraft.

2. Multiple Protection Mechanisms

   • Overcurrent Protection: Automatically limits power output when current exceeds 300A, preventing hardware damage.
   • Overtemperature Protection: Reduces output power when the ESC temperature is too high, ensuring stable operation under extreme conditions.
   • IPX4 Water Resistance: Protects against splashes and light moisture, suitable for operations in rainy, foggy, or humid environments.
   • Short-Circuit Protection and Signal Loss Protection further enhance reliability and flight safety.

3. High-Performance 32-bit Processor

   • Utilizes the latest 32-bit MCU for faster response and more precise motor control.
   • Optimized algorithms deliver smoother motor startups and stable operation; supports firmware upgrades as needed.

4. Robust Construction & Heat Dissipation

   • Carefully engineered heatsink and metal enclosure effectively dissipate heat, ensuring safe, stable performance under high current loads.
   • Overall dimensions of approximately 93.5 × 78 × 32 mm and weight of around 420 g, balancing compact size with efficient cooling.

5. Easy Installation & Connectivity

   • Convenient terminal design supports various wire gauges for power and motor leads.
   • Multiple interface options (signal wires, power leads) allow seamless integration with mainstream flight controllers and power systems.

2. V2.0 Highlights

For users seeking enhanced functionality and more flexible flight controller interaction, we highly recommend the V2.0 CAN version. Building on the proven performance and safety features of the original model, V2.0 adds or upgrades the following:

1. Dual Throttle Control

   • RPM Control + CAN Control: Switch or combine modes depending on your flight controller’s requirements, enabling more precise and efficient motor speed control.

2. Firmware Upgradeability

   • Supports firmware updates via a dedicated interface or CAN bus, ensuring you can access the latest features and security patches.

3. BEC Output

   • Integrated 5V/200mA BEC output powers small external devices (e.g., receivers or sensors), reducing system complexity and wiring.

4. Overload Protection

   • Unlimited automatic restart: In the event of overload or unexpected errors, the ESC will automatically restart to quickly recover normal operation.

5. Real-Time CAN Communication

   • Provides real-time data (voltage, current, temperature, operational status) to the flight controller via CAN. This allows the FC to monitor performance and detect faults, improving overall safety and intelligent control.

4. Troubleshooting

1. No Motor Response after Power-Up

   • Check power leads, signal wires, and battery voltage for correct connections.
   • Ensure ESC, flight controller, and motor parameters are properly matched.

2. Unstable or Shaking Motor Operation

   • Check that propellers and motor shafts are securely mounted.
   • Update ESC firmware or adjust ESC settings to optimize control parameters.

3. ESC Overheating or Automatic Power Reduction

   • Improve cooling or reduce operating load; avoid running at maximum current for extended periods.
   • Ensure motor/propeller selection is appropriate for the ESC’s capacity.

4. CAN Communication Issues (V2.0 only)

   • Verify proper CAN wiring and pinouts between flight controller and ESC.
   • Confirm firmware versions and flight controller compatibility.

5. Precautions & Disclaimer

1. Before Installation

   • Read the product manual thoroughly and comply with local laws and regulations regarding drones and electronic devices.
   • Ensure motors, propellers, flight controllers, and other components are securely installed; check that all screws are tight.

2. During Operation

   • Do not exceed the ESC’s rated voltage/current range.
   • Avoid operating at full load in extremely hot, humid, or harsh environments for prolonged periods.
   • Keep the ESC out of children’s reach and ensure operators are familiar with safe flight practices.
