wats the difference between 15C and 20C? I read some where that higher C = higher life cycles. Is that true?

"C" refers to the discharge rate. Generally, the "C" number is the constant discharge rate that the cell/pack is capable of.
For example, a 20C 3200mah pack is capable of 64 amps constant current, and bursts of higher amps. A 15C 3200mah pack is capable of 48 amps constant current, and bursts of higher amps.
"C" stands for "capacity". 20C means 20 times the packs' capacity. Therefore a 3200mah (which is 3.2amps) at 20C is 20 times 3.2, or 64 amps.
That said, a pack with a higher "C" rating is safer at higher amp draws so logically would have a longer life than a pack with a lower "C" rating used in the same higher draw application.
