It's normal for the battery voltage to drop that low when you're pulling a lot of current with the drive motors. It's not normal for anything to reboot until you've managed to get the voltage down below 5 volts. If you're getting reboots at 9 volts, you're probably not connecting to the right output of the Power Distribution Board. Check to make sure you're getting 12 volts on the dedicated boosted radio supply going into the 12-to-5 converter, and make sure you're getting 24 volts on the dedicated boosted cRIO supply.
