The Castle BEC Pro (Battery Eliminator Circuit) is a small device that eliminates the need for a receiver battery.
It draws voltage from the motor batteries and drops it to a voltage level that is suitable for your receiver and servos. This is required in applications which use high-power servos, where the ESC does not have an internal BEC, or the existing BEC is inadequate.
The Castle BEC Pro is designed to operate at up to 12S LiPo (50.4V) with a 20A peak servo load.
20 amps peak
Maximum continuous current -
16V input = 15A
24V input = 13A
32V input = 11A
