I made a Hexapod with 12 power hungry servo motors, I am using this Buck Converter to step down from 4S LiPo about 16V to 6V to power all the 12 servo motors. So far, it worked perfectly. I love that the display shows input voltage, so I know when the battery is discharged. I like the ON/OFF button, but it would have been nicer if it would turn off the input (the hole thing) instead of the output only leaving the display still on.
