The battery comprises a battery pack of 400V, generally used in electric vehicles. Since a single cell cannot provide such voltage or power levels, multiple cells are connected in series and parallel to create the desired battery pack. The battery pack in this example comprises 10 modules, each with 11 series-connected parallel sets (p-sets).
Discharge time is basically the Ah or mAh rating divided by the current. So for a 2200mAh battery with a load that draws 300mA you have: $frac{2.2}{0.3} = 7.3 hours$ * The charge time depends on the battery chemistry and the charge current. For NiMh, for example, this would typically be 10% of the Ah rating for 10 hours.
