Yes more current available. Longer run times. With more current availalbe you have more acceleration. Say you have a 3s 20C 3ah pack. At most you can draw 60A. Now put two packs in parallel. The voltage stays the same but now think of it as one 3s 20C 6ah pack. Now your current draw capability doubles to 120A. So you havbe more juice availalbe when you need it. But you need to be careful. Make sure your ESC can handle that current draw. When you hook packs in parallel the AH adds. When you put the in serial the voltages add.

Hope you understand.
