Different Batteries

According to the specs the cRIO draws only 20 watts. The recommended power supply is 48 watts, or 2 amps at 24 volts. The upconverter should have an efficiency of about 80% so the input current with 10 volts on the battery should be about 2.5 amps. If your stalled motors drop the battery down to 5 volts the input power to the upconverter may rise to 5 amps but this is nothing compared to 100 amps pulling down the battery.
The primary concern is maintaining glitch free power so that the robot controller doesn't reset during the low voltages that result from motors operating near stall conditions. The design of the new PDU looks pretty good at covering this issue.
