Core Features & Benefits
1. Professional AM32 Firmware for High-Voltage Efficiency & Precise Response
Powered by the advanced AM32 open-source ESC firmware with optimized driving algorithms for high-voltage high-current scenarios, it delivers lower conduction loss and finer throttle linearity than traditional solutions, effectively improving overall power system efficiency and extending flight time for long-endurance missions. With native support for DSHOT300 and DSHOT600 high-speed digital protocols, it achieves ultra-low signal latency and responsive power output, providing smooth and controllable power delivery for both steady cruising and aggressive maneuvering.
2. 65A High Current + 2-8S Wide Voltage for Heavy-Lift Professional Models
Adopting 4 independent high-power drive circuits, each channel delivers up to 65A continuous current with ample peak current headroom, easily driving large industrial brushless motors such as 3508 and 4012 specifications. It fully meets the power demands of professional models including 13/15 inch large long-range drones, heavy-lift aerial photography UAVs and surveying & inspection aircraft. With wide 2S to 8S LiPo input support, it is compatible with both lightweight long-endurance configurations and high-voltage high-power setups, covering diverse application scenarios.
3. Industrial-Grade Circuit Design with Reinforced Thermal Management for Long-Term Stable Operation
It adopts thick high-conductivity copper PCB layout with optimized high-current paths, effectively reducing line resistance and operating heat, and ensuring consistency and long-term stability across all four channels. Paired with a large-area high-efficiency heat dissipation structure and optimized thermal design, it quickly dissipates heat generated during long full-throttle high-load operations, avoiding overheating throttling or power failure, and greatly improving device reliability and service life for long-range and continuous mission scenarios.
4. Standard Stack Mounting for Wide Compatibility
It adopts industry-standard mounting holes for large-size 4-in-1 ESCs, enabling direct stack installation with matching flight controllers for clean wiring and greatly reduced assembly complexity for large UAVs. It is compatible with most mainstream industrial flight controllers and 13/15 inch airframes, making it convenient for both new system builds and existing power system upgrades.
5. Full-Range Protection + Flexible Tuning for Diverse Operation Scenarios
Built-in multiple hardware and software protection mechanisms including over-current, over-voltage, under-voltage, over-temperature and stall protection fully ensure the safe operation of the power system and reduce failure risks in professional operations. It supports online parameter adjustment and firmware upgrade via the flight controller with no extra programmer required. Users can customize throttle curves, start braking, protection thresholds and more settings, flexibly adapting to different operation scenarios such as long-range cruising, heavy-load transportation and surveying inspection.
