2S-8S ZTW UBEC 8A G2 5V 6V 7.4V 8.4V Adjustable 15A Peak RC Airplane ESC

ZTW UBEC 8A G2 External Switching BEC 2-8S 5V/6V/7.4V/8.4V Adjustable 15A Peak for RC Airplane, Drone, Car and Servo Power

8A Continuous / 15A Peak Switching BEC

The UBEC 8A G2 delivers 8A continuous and up to 15A peak output current — enough to power multiple digital servos, a flight controller, and peripheral electronics simultaneously without overloading the ESC's built-in BEC.

2-8S Wide Input Voltage

Accepts 2S to 8S LiPo directly, covering small park flyers, 4S 1/10 cars, 6S FPV platforms, and up to 8S large-scale models in a single compact regulator.

Four Selectable Output Voltages

Output voltage is adjustable between 5V, 6V, 7.4V, and 8.4V via an onboard DIP switch, matching the requirements of standard analog servos (5V), high-voltage digital servos (7.4V/8.4V), and 6V receiver systems.

High-Efficiency Switching Topology

Switch-mode regulation runs cooler and wastes less battery energy than linear BECs, maintaining stable output voltage even when the input battery sags under load — critical for preventing receiver brownouts during aggressive 3D maneuvers or heavy servo loads.

Compact 14g Form Factor

At 50×20×7mm and just 14g, the UBEC 8A fits easily inside narrow fuselages, car radio boxes, and drone frames. The 22AWG input leads and JR-style output connector simplify installation.

Clean Power for Sensitive Electronics

The switching regulator isolates servo and receiver power from motor noise, providing a clean supply for flight controllers, gyros, and telemetry systems — reducing glitches and interference in both RC and professional UAV setups.

Versatile Across RC & Industrial Applications

Suitable for RC airplanes, helicopters, drones, cars, and boats, as well as robotics and small industrial actuator projects requiring a stable, adjustable low-voltage supply from a high-voltage battery.
