BEC/UBEC Units for RC Cars & Models

Part of our Speed Controllers range, BEC/UBEC units keep your radio gear supplied with clean, consistent power. A BEC sits between your main drive battery and the receiver, regulating voltage to your RX and servos so they stay responsive and protected. Whether you're upgrading a high-torque crawler, running HV servos in a 1/8 buggy, or converting a nitro model to electric, you'll find compact linear BECs and efficient switch-mode UBECs to suit. Choose by input voltage range, continuous and peak current rating, and adjustable output (typically 5-8.4V) to match your servo and receiver requirements. We stock trusted options from Hobbywing, Castle Creations, ZTW and Traxxas, including waterproof units, noise-filtered designs, and easy-to-wire modules with JR/servo plugs. Using an external BEC? Remember to remove the red wire from your ESC's receiver lead to avoid dual-power conflicts. Need help with wiring or selecting the right amperage?
