Castle Creations CC-BEC PRO Battery Eliminator Circuit
Need a BEC to drive a really large load? Useful for high servo counts or many digital servos on larger craft. Use as a power supply aboard your UAV to drive sensor, transmitters or whatever your client has you testing.
NOTE: CC BEC Pro should never be operated in series or parallel with another BEC or backup receiver pack connected to the RX/Servo side of the circuit.
Size: 1.69" (43mm) x 1.3" (33mm) Height: 0.94" (24mm) Weight: 1 oz* (29g*) Max Amps: 20 amps peak** Max Volts: 2s to 6s LiPo Cars: 6s (25v), Airplanes: 10s (40v), Helicopters (with brake disabled): 12s (50v) Adjustable Output Voltage :4.8V to 12.5V
*Weight without wires **Ratings are determined with a 5mph airflow on the BEC.
Advice from Dave on setting voltage: For simulating a typical 4.8V RX pack set voltage 5.1 to 5.4. For simulating a 6V pack, set voltage to 6.4 to 6.8. Battery packs are not any set voltage but work over a range of voltages. Think about what your trying to simulate. A 4.8v pack is empty at about 4.4v, full at about 6v. A 6v pack is empty at 5.5 and full at about 7.5. For heli's where the tail servo and gyro won't take 6v packs, what the MFG is saying is it won't take 7.5V. Setting heli voltage to even 5.8 or 5.9 is fine as it just looks like a 4.8V pack hot off the charger. For older 2.4GHZ systems (Anything not Hitec/Airtronics and pre 2011 gear) we reccomend setting voltage to 5.4-6V range MINIMUM.
