Ok...
Series involves linking all the cells plus to minus. So the entire pack spec will mimic a single cell. So a 6s or 2 3s packs wires in series is the same thing.
eg, 6, 3000 30c cells wired in series will give you a 6s 3000 30c pack.
Parallel wiring takes 2 sets of X number of cells wired in series and wires both pos and neg of those X number of cells together.
eg, you have 2, 3s 3000 30c packs and after you wire them in parallel you will have 3s 6000 30c.
C rating refers to the ability of the cell to produce amps. It is simply a number that you multiply by the pack's amp capacity rating to determine what the pack can output.
eg, the 3000mah 30c pack can output 90amps. You get this by multiplying the 30c by the packs AMP/hr rating (3000 milli amp hour-mah = 3 amp hour)
So 30 x 3 = 90
So you see that the packs capability is related to both its capacity (mah) and the C rating. Voltage is not important when doing the math for pack amp discharge.
Total available power is determined by finding the discharge capability (as shown above) and multiplying it by the pack voltage.
So our 6s 3000 30c pack would be capable of 1998 watts. 22.2v (=6s) x 90amps = 1998 watts.
