2-13S Input 5V 5A BEC Voltage Regulator

A step-down BEC that accepts 2S to 13S battery voltage and delivers a regulated 5V at up to 5A. It suits heavy-lift, agricultural and other large multirotor builds that need a clean 5V rail for a flight controller, receiver, GPS or servos taken straight from a high-voltage pack.

Key features

• Wide input range from 2S to 13S, so one regulator covers everything from small trainers to very large airframes.
• Around 95% conversion efficiency, so little power is lost as heat when stepping down from a high-voltage pack.
• Output short-circuit and overheat protection to safeguard the electronics on the 5V rail.
• Operating temperature of roughly -45°C to 85°C for hot field days and cold mornings alike.

Specifications

• Input: 2-13S LiPo
• Output voltage: 5V
• Output current: 5A
• Efficiency: about 95%
• Operating temperature: -45°C to 85°C
• Protection: output short circuit, overheat

Add up the draw of everything on the 5V rail before wiring it in: servos and high-power peripherals add up quickly, and 5A is the ceiling.
