Mini 12V 3A UBEC for 4S-6S LiPo

A compact step-down UBEC that turns a 4S to 6S LiPo into a steady 12 V supply. It feeds 12 V devices — video transmitters, FPV and HD cameras, LED strips — straight from the main flight pack on quads, hexacopters and fixed-wing models.

Key features

• 4S–6S input: works from 14.8 V nominal up to 25.2 V on a fully charged 6S pack.
• 36 W on the rail: 12 V at 3 A continuous, enough for several 12 V accessories sharing one rail as long as their combined draw stays under 3 A.
• Switching regulation: steps 6S down to 12 V without the heat a linear regulator would shed.
• Protection: over-current, over-voltage and thermal protection.

Specifications

• Input: 4S–6S LiPo (14.8–25.2 V)
• Output: 12 V, 3 A continuous
• Protection: Over-current, over-voltage, thermal

Not for 2S or 3S builds: a step-down regulator needs an input above its output, and a 3S pack (11.1 V nominal) cannot hold a 12 V rail — choose a 5 V or 2–6S UBEC there. Check the output with a multimeter before connecting electronics.
