need help on lipos..

[smm_cbf]

im thinking of swiching from cells to lipo, but i already know that you have a little more run time and they don't decline the speed of the rc during running but i don't get what 20c(example) and 4s means?

A 5000 mah battery discharged at 1C would be 5 amps. Then 20C would 100 amps.

And 4S simply means 4 cells in series.
Each lipo cell is rated at 3.7 volts so 4S = 14.8 volts.

And when it says 4s1p 3700mah, that mean 14.8V one time and 3700mah. and 4s2p 3700mah would mean 14.8v 2 times in parallel giving 7400mah.
