The battery is still being difficult.
It's supposed to be around 11V and 3A/hr, but when it is connected to the robot, it's 5V and 0.1A.
When the power supply is connected to the robot, it can handle 11V to 12V and about 0.88A.
Someone suggested looking into power ratings of the battery.
A problem occurred while trying to test the battery, one of the wheels wasn't rotating backwards anymore. We tested the output voltage of the Stellaris pin that handles direction. It should be a high voltage (3.3V) for forward, and then a low voltage (millivolts) for backwards. The low voltage wasn't low enough, it was outputting about 1V. The other three motor control wires were working fine; it was just that one output.
Solutions:
Research more about this battery and ask a professor's opinion
Change the output pin on the Stellaris
