FlightPower batteries have become hard to obtain, but there are still some packs available - and they are the new generation packs that can be charged at higher rates, give more amps and more power. (Photos show the older series EVO)
The chart below lists the Flightpower battery packs currently available (as at 10-10-09). The Cell Type column refers to the type of cell and the mAh capacity of the pack. Each cell is 3.7V, so two cells in series (2S) will be 7.4V, and three cells (3S) will be 11.1V, etc. Each of these packs is 1P, or one lot of cells.
To gain 2P (two lots of cells in parallel) you buy two packs and hook them up in parallel. Then you will have double the capacity, and double the Amp capability, but the same voltage. For example, a 1200 3S pack will be 11.1V and capable of delivering 36A continuous and 43A in bursts (if it is a 30/36C pack). Put two packs in parallel (3S2P) and you will still have 11.1V, but 2400 mAh capacity and 72A continuous capability (and 86A bursts).
You can see that the available packs vary in their amps capability - I have given C rating - this means that you multiply the C rating by the capacity in Ah. So, a 1600 mAh pack of 25/40C rating will give 25 x 1.6 = 40A continuous and 40 x 1.6 = 64A in bursts of up to 15 seconds.
