Thanks, that's what i needed to know, so the 3S means 3 cells, and the 2p is two packs in parallel? As you can see im new to lithium batteries.

Correct. As you increase the number of cells in S (series) you increase voltage..as you increase the number of P (parallel), you increase the amount of amps that the pack can handle as well as the total pack capacity (ie- runtime) . Lets say the 3S 2100 pack can handle 21 amps (10C), then when you combine another 3S in Parallel to form a 3S2P you now have a 42 amp capable pack and have doubled your capacity from 2100 mah to 4200 mah thus extending your runtime.
