It's easier to think of C as the size of pipeline to a big water tank... if your thirst (motor) is asking for more water you can only get so much of it through a narrower pipe.... but with a bigger pipe, the tank empties faster.

This is why good techs will tell you more C and mAH is desirable in a lipo. Too narrow of a pipe is greater electrical resistance, which will create heat. If your load is too great, even momentarily for the startup, long term usage like that can cause damage to the cells. When the cells start to break down they will start to outgass and swell.

If you can't fit mah, get C, if you can't fit either, change the battery configuration or location so you can. This is why I keep telling people with massively upgraded m4s to stop using buffertube lipos... most of them can't supply the 100+A of startup current needed for big neo motors.
