Default Lipo battery current draw question...

I have a 1:10 scale drift car that uses a standard 550 brushed motor. It is rated to use a 7.2V nimh battery but I have been running a 5000mah 2s lipo 30c with no problem.

My question is, can a 15c lipo handle the current load for a 550 motor in a car like this, or will it over-draw current and potentially catch the battery on fire? What about 10c?

The current draw depends greatly on how the car is geared. If it is running stock gearing and tires then you will be fine with a 15c or even a 10c pack.
Your 30c/5000 pack can deliver about 150amps in a burst and that is where you might be if you had a brushless set-up with some tall gearing.
A 15c/5000 pack could deliver about 75 amps and a 10c pack about 50amps.
The rule of thumb for lipos is ; always buy the highest "C" rating pack that you can afford and that will fit into your vehicle.
