This small and lightweight Battery Eliminator Circuit (BEC) can be used in place of a dedicated battery to power your receiver and servos.
At a pre-determined voltage, the BEC will shut down power to the motor while continuing to power your receiver and servos.
The HobbyKing™ Micro BEC 2A/5v features highly efficient switch mode circuitry that provides better heat dissipation compared to linear voltage regulation. The shielded PCB design and output EMF coil provide a stable, low noise voltage output.
This BEC also features built-in reverse polarity protection.
Type: Switch mode BEC
Input: 6V~17V (2~4S LiPoly)
Output: 5V/2A Constant
Dimension: 12 x 12 x 7mm
Always double-check the polarity before connecting battery.
Small, light, efficient, cheap, and easy to solder your own wires after you peel off the funky heat shrink. The chip labeled 4R7 sticks up a bit, but it actually serves as a nice anchor if you dig a cavity in the body of your drone for that chip to fit into, and hot glue the BEC with the flat side facing out.
