The limited voltage range of the 9.04 means you can't run it on 16.8V maximum output 4S LiPos?
I guess you could use a separate 5V converter to power the board, if it allows servo power to be separate?

[Gort]

What servos are you running with that setup?

[jwatte]

MX-64. They are rated for 4S LiPo according to Robotis support.
