BECs & Voltage Regulators

A BEC (battery eliminator circuit) steps battery voltage down to a steady 5V, 9V or 12V for flight controllers, cameras, video transmitters, servos and companion computers. Check three numbers: the input range must cover your pack (from 2S up to 12S or more on high-voltage units), the output voltage must match the device, and the rated current needs headroom over the load. We stock Mateksys, iFlight, Flywoo and TBS regulators, plus simple UBEC modules. For current sensing, see PDBs & Power Modules.
