BEC & UBEC Regulators

A BEC (battery eliminator circuit) steps the flight battery voltage down to a steady supply for your receiver and servos, so you do not need a separate receiver battery. This category includes external BECs and UBECs from brands such as Castle Creations and Spektrum, plus BEC spares.

Check the input voltage range and output current in each product description to make sure it suits your battery and servos. For related parts, see the Voltage regulator and ESC categories.
