I am currently using the Adafruit Motor Shield in conjunction with an Arduino Motor Shield to control two 7.2V DC Motors. The DC Motors are being powered by a 7.2V, 3000 mAh Nimh battery. When the two DC Motors are being powered in parallel directly by the Nimh battery, they are able to move rapidly and drive their load (a fairly heavy colson wheel). However, when used with the Adafruit Motor Shield intermediary, they are unable to draw enough current and hardly move at all. Is there any way I can make provide the motors with more current or force them to draw more current through the Motor Shield? I am currently only using the arduino board to stop the vehicle at a specific point and just need a way to stop the motors after a desired point. If I cannot increase the current drawn by the motors, is there any other way I could stop the motors with the two motors directly connected to the power supply.
