LiPos and Amp Discharge

[GeeReg]

I'm trying to get into lipos and I'm looking at the discharge rates. I'm trying to figure out what kind of rate I need and what is too little or too much. If I have a motor with a max amp rating of 69 say, what does that usually equate to for continuous discharge? I realize it depends on a lot of variables such as vehicle weight and terrain, but is there a general rule? What happens if the max discharge of the lipos is less? They will get hotter faster and easier and I lose performance correct? What should I be looking at for continuous discharge for my brushless MT (Feigao 380 6L) or something like a Novak SS+ 5800 in my T2?

I also might use them in a brushed setup and have no idea how much something like a stock 27t uses. I'm assuming it's pretty low.

Basically I'm wondering if/when I need to parallel the cells because I'd like to minimize the cost so if it's not needed I won't.
