Matek PM20S-2 Power Module (3–20S, 2× BEC)

Matek PM20S-2 is a high-voltage power module for larger FPV, long-range and industrial multirotor builds that need clean, regulated power and accurate battery monitoring from the same board. It accepts a wide 3–20S pack input, making it suitable for everything from typical 4–8S setups up to high-cell-count platforms where direct battery voltage cannot be fed to most flight controllers.

Key features

• Wide input range: supports 3–20S LiPo/Li-ion builds, ideal for high-voltage rigs and endurance platforms.

• Dual onboard BECs: two regulated outputs let you power a flight controller and separate peripherals (GPS, VTX, receiver, servos) without adding external regulators.

• Integrated voltage & current sensing: provides battery voltage and current data to your FC for OSD, logging, power draw and capacity calculations.

• Cleaner wiring: centralises power distribution, regulation and sensing to reduce extra boards and inline sensors in the stack.

Specifications

• Model: PM20S-2

• Input voltage range: 3–20S

• Outputs: 2× BEC (regulated)

• Sensing: Voltage, current

Use this module when your flight controller needs a safe regulated supply while you still want accurate battery telemetry; confirm your FC supports analogue voltage/current inputs and choose which BEC rail powers noise-sensitive gear like GPS and video.
