Hexy Power Help

I wanted to power my hexy with a LiPo battery (7.2V 2200mAh) so I connected the logic board directly and stepped down the voltage to 6V for the servos. The servos work fine with the stepped down voltage. However, now the only way i can get the board to power on is with usb power it wont even power from the stock battery pack with recommended batteries. I double checked the output voltages with a multi meter and made sure everything was wired correctly Did I fry the board or am I just doing something wrong?

Sounds like it probably a bad voltage regulator. Since you have a multimeter, can you measure the voltage at these three points? Those readings would let us know for sure. If it is, we can get you a replacement.
