Hobbywing 3A UBEC, 5V/6V Output (2-6S Input)

Hobbywing external switching UBEC that steps a 2–6S LiPo supply down to a stable 5 V or 6 V rail for receivers, servos and other low-voltage electronics. It suits fixed-wing builds whose ESC has no built-in BEC, and multirotors that need a separate rail for servos or a payload.

Key features

• 3 A continuous output at 5 V or 6 V, selected with a jumper
• Wide 5.5–26 V input: 2–6S LiPo or 5–18 cell NiMH
• Switching regulator, so it runs far cooler than a linear BEC on high-voltage packs
• Clean output with ripple under 50 mVp-p
• Slim 43 × 17 × 7 mm body tucks into a fuselage or under a frame plate

Specifications

• Input voltage: 5.5–26 V (2–6S LiPo / 5–18 cells NiMH)
• Output voltage: 5 V or 6 V, jumper-selectable
• Continuous current: 3 A
• Output ripple: under 50 mVp-p
• Dimensions: 43 × 17 × 7 mm
• Part number: 86010010

3 A covers a receiver and a few standard servos; several high-torque digital servos moving at once can exceed it, so choose a higher-current BEC for those. Set the jumper to 5 V for flight controllers and receivers, and use 6 V only when every connected device accepts it.
