A battery with a discharge rating of 30C would mean you could theoretically safely discharge it at a rate 30 times the capacity of the pack. Using our 1000 mAh battery as an example; if it has a 30C discharge rating, that would mean you could pull a maximum sustained load of 30 x 1000 milliamps = 30,000 mA or 30 Amps.

What is the maximum current which can pass in a Li_ion battery?
As a rule of thumb small li-ion or li-poly batteries can be charged and discharged at around 1C. "C" is a unit of measure for current equal to the cell capacity divided by one hour; so for a 200mAh battery, 1C is 200mA. Example: common 402025 150mAh battery from Adafruit: quick charge 1C, maximum continuous discharge 1C. ...
