Hah? You always connect batteries in parallel when you want greater current capacity. You are thinking in terms of an ideal power supply, where the current always tracks exactly with the resistance and voltage. Just because you have a given resistance and a given voltage of battery doesn't mean that you will get the calculated current when you hook it all up... if that were true, you could hook up a single AA cell with a centimeter-thick copper conductor and get more than 200,000 amps of current. The battery just can't pump out electrons that fast.
