Last year when we did these tests, we checked two S ones from the prior year and two X ones from the current year. The two S ones were very close to each other in capacity, and the two X ones were very close to each other (within a few percent). One can't draw conclusions from a sample of two, but the moral of the story is that you need to test the capacity of your batteries and qualify them for competition use. A good battery does not make good robot great, but a bad battery will definitely make a great robot marginal.
