One way to tell is to double the capacity of the battery and rerun the test.

I noticed in the test that with the 840mah (I think that was the capacity) the amp spikes were lower than with the 1550mah pack. It looks like something is happening to cause the system to draw as much as the battery can possibly put out. If you double the pack capacity again and the amp draw continues to rise I would say there is something else worng besides the battery. Something in the system is causing the battery to basically dead short and just dump everything it can.
