In the middle of this long post, Link to VexLabs Forum you can find some calculations for how long a battery can last across a series of VRC matches. In practice, most folks swap them more often than the simple calculation predicts is necessary.
How well the battery has been treated (Don't slap them on a charger after every use. Fully discharge them before charging them (down to around 5 V)) and how old it is will strongly affect how it stands up (does its voltage dip) when hit with a high demand for current.
