Matek 12S Pro BEC (9–55V to 5V/8V/12V 5A)

The Matek 12S Pro BEC is a high-voltage step-down regulator engineered for heavy-lift cinelifters, X-Class rigs, and agricultural drones operating on high-cell-count powertrains. Delivering a continuous 5A output from a wide 9V to 55V input range, it steps down main battery voltage to provide clean, stable power to high-draw peripherals like servos, high-powered video transmitters, gimbals, and cinema cameras without straining your flight controller.

Key features

• Accepts a 9–55V input, directly supporting large 3S to 12S LiPo battery configurations without secondary regulators.
• Output voltage is easily configured to 5V, 8V, or 12V via dedicated solder jumper pads to match your specific electronics.
• Synchronous switching buck regulator design ensures high power conversion efficiency and minimises excess heat generation.
• Integrated thermal shutdown, over-current, and short-circuit protections safeguard your expensive connected payloads.

Specifications

• Input Voltage: 9–55V (3–12S LiPo)
• Output Voltage: 5V, 8V, or 12V (selectable)
• Output Current: 5A continuous (8A peak burst)
• Regulator Type: Synchronous step-down (buck)

When installing this BEC on 8S to 12S builds, ensure the board is mounted with adequate airflow. Always wire an appropriately rated low-ESR capacitor to the main battery input to protect both the BEC and your flight electronics from high-voltage plug-in spikes.
