Can someone clue me into the meaning of the cryptic lipo battery descriptions:

If I understand correctly xS is number of cells, so 3S is 3 cell and 4s is 4 cell. But what is 3S1P?

I think C is discharge rate, so an 18C can discharge 18 times as much current as a 1C, likewise 25C can discharge 25 times as much? This has to do with how much power you can send to the motor, so in effect, how much power you can get? So a 20C would give you twice as much power as a 10C but would have only half the flight duration (assuming all other numbers were equal)?

The last is the mAh measurement. This is capacity? so a 2500 can hold 25% more charge (and hence 25% more flight duration) than a 2000? Does the increased weight of the 2500 shorten that some?
