A Battery Eliminator Circuit (BEC) is a voltage regulator used in radio-controlled models like quadcopters, FPV racing drones, etc. It steps down the high voltage from the battery (2S-13S, 8-55V) to a stable 5V for powering the electronics that require a lower voltage.
The BEC you mentioned is capable of delivering up to 5A of continuous current, which should be enough for most standard setups.
Key Features
Benefits of using a BEC:
-
Stable Power Supply: Ensures a constant 5V output even when the battery voltage fluctuates during flight.
-
Reduced Weight: Eliminates the need for a separate receiver battery, making the model lighter.
-
Simplified Wiring: Fewer connections are needed as the BEC is integrated into the ESC.
-
Protects Electronics: Prevents damage to sensitive electronics that can't handle high voltages.
Please note:
-
Ensure the BEC you choose is compatible with the voltage of your battery (2S-13S).
-
If you have a high-power setup or use many servos, you might need a BEC with a higher current rating.
