MAD AMPX 300A (12–24S) HV Drone ESC – Product Description
The MAD AMPX 300A (12–24S) HV Drone ESC is a high-performance electronic speed controller designed for demanding applications such as heavy-lift drones, electric paramotors, and other high-power aerial or industrial systems. It supports a wide voltage range from 12S to 24S (approximately 40 V to 100 V) and provides a continuous current of up to 300 A, ensuring powerful and reliable propulsion in extreme load conditions. Multiple protection features and an IPX4 rating make it well-suited for professional and industrial environments where safety, efficiency, and durability are paramount.
Key Features
• High Current Capability
Supports 300 A continuous current, making it suitable for heavy-lift and high-thrust operations.
• Wide Voltage Range
Operates efficiently from 12S to 24S (40–100 V), accommodating various battery configurations.
• IPX4 Protection
Offers protection against water splashes and dust, ensuring reliable performance in challenging outdoor conditions.
• Advanced Control & Protection
Integrates over-voltage, under-voltage, over-current, and short-circuit protection. V2.0 and V3.0 include refined voltage protection mechanisms; V3.0 additionally features a brake function for paramotor applications.
• Flexible Signal Options
Depending on the version, supports standard PWM input or CAN communication for real-time monitoring and parameter adjustments.
• Optimized Cooling Design
Features a robust heat-sink structure and aluminum casing to maintain stable performance under continuous high loads.
Version Information
• V1.0 – Basic version with PWM control only, no CAN communication or BEC.
• V2.0 – Includes CAN communication and a built-in BEC. Intended for drone use, with firmware optimized for aerial platforms. Features an advanced voltage protection mechanism.
• V3.0 – Designed for electric paramotor applications, featuring CAN communication, paramotor-specific firmware, a brake function, and compatibility with powered paraglider setup boxes. Incorporates a specialized voltage protection approach to meet the safety demands of paramotor flight.
Recommended Motor and Propeller
The AMPX 300A ESC works exceptionally well with the M40C30 pro IPE 43 kV motor, especially when paired with a glossy 47.5 × 17.4 in carbon fiber propeller. This combination delivers high thrust, smooth operation, and efficient power usage for large-scale drone or paramotor setups.

Installation & Usage Guidelines
Ensure correct polarity and use cables rated for high current. For V2.0 or V3.0 units, connect the CAN lines properly if using advanced communication features. Provide sufficient airflow or cooling space around the ESC, and securely mount it to minimize vibration. When first testing, start with minimal load to verify motor rotation, temperature behavior, and protection functions before applying full operational loads. Regularly inspect all connections, wires, and mounting hardware.
Common Issues & Troubleshooting
• Motor Not Starting
– Check battery voltage, ESC wiring, and flight controller signal output.
• Motor Stuttering or Vibration
– Confirm correct motor phase wiring and flight controller motor mapping.
• Overheating or Shutdown
– Ensure adequate cooling and confirm that motor/prop specifications match the application’s load requirements.
• Low Voltage Alarm
– Verify battery capacity and discharge rating; recharge or replace the battery if necessary.
Safety & Disclaimer
Operate in accordance with local regulations governing high-power drones or paramotor flights. Maintain a safe distance from people and property, and perform regular system checks. Any modifications or non-original parts usage may lead to unforeseen risks. Always follow the manufacturer’s guidelines and ensure that all components are securely fastened.
Applicable Scenarios
This ESC is well-suited for large-scale drone applications requiring heavy payload capacities, extended flight durations, or high-altitude operations. It also excels in electric paramotor setups (particularly with the V3.0 firmware), industrial robots, special-purpose vehicles, and other high-power electric propulsion systems.
