YRRC 2-13S 5V 5A BEC Module

The YRRC BEC module steps a 2–13S LiPo pack down to a regulated 5 V supply at up to 5 A, so flight controllers, receivers, telemetry radios and other 5 V electronics can run straight off a high-voltage flight pack. It suits heavy-lift, agricultural and long-range builds where the pack voltage is beyond what the flight controller or PDB regulator accepts.

Key features

• Wide input: 7.4–55 V, covering 2S to 13S LiPo
• 5 A continuous at 5 V, or 25 W for avionics and servos
• High-efficiency switching conversion, so it runs cooler than a linear regulator at high input voltage
• Overcurrent and thermal protection to protect the module and the electronics it feeds
• Compact: 35 × 19 × 9 mm, easy to tuck into a crowded frame

Specifications

• Input voltage: 2–13S LiPo (7.4–55 V)
• Output voltage: 5 V
• Output current: 5 A continuous
• Dimensions: 35 × 19 × 9 mm

A fully charged 13S LiPo sits at 54.6 V, just inside the 55 V limit; a 13S LiHV pack (about 56.6 V full) exceeds it. Add up the 5 V load of your flight controller, receiver, GPS and servos and keep it below 5 A.
