I find this a bit worrying that people are using lipo's and not understanding how it all works and even more worrying is they are giving other people advice.
Lipo's are given a safe discharge rate that is there so you can choose a combination of battery/motor/esc that does not draw more current than they are safely rated at.
The battery will be able to deliver more current than it's rating but you run the risk of damaging the battery.
Do some research before using lipo and read up on hard facts.
There is already alot of assumptions and opinion in this thread mixed in with a few facts.
I'm not normally this serious but lipo's are potential fire crackers
