That depends entirely upon if you are using a mechanical or regulated mod. If you are using a mechanical mod, it also depends upon how low resistance coil you are using. Using an Ohm's Law calculator for a mechanical mod:

1.0 ohm = 4.2 amp draw
0.9 ohm = 4.6 amp draw
0.8 ohm = 5.2 amp draw
0.7 ohms = 6 amp draw
0.6 ohms = 7 amp draw
0.5 ohms = 8.4 amp draw
0.4 ohms = 10.5 amp draw
0.3 ohms = 14.0 amp draw
0.2 ohms = 21.0 amp draw
0.1 ohms = 42.0 amp draw
0.0 ohms = dead short = battery goes into thermal runaway

For a mech mod, the lower you build the more current is drawn from the battery. If you're using a 20 amp CDR battery, you shouldn't build lower than 0.3 ohm, because a 0.2 ohm coil will draw over 20 amps. If you use a true 30 amp CDR battery, you can build down to 0.2 ohm. 0.1 ohms draws 42 amps from the battery, which is way higher than any battery on the market.

For a regulated mod, a different formula is used. Calculating battery current draw for a regulated mod

If you haven't figured it out by now, the battery's amp rating is the most important spec. Also called the continuous discharge rating. The top battery manufacturers are AW, LG, Samsung, and Sony.

Probably the top three batteries on the market today for general purpose vaping are the:

LG HG2 3000mAh 20A CDR

Samsung 30Q 3000mAh 20A CDR

AW 3000mAh 20A CDR

All three have nearly identical specifications with a 20 amp limit and 3000 mAh capacity; a nice mix of current capability and charge duration.

If you need a true 30 amp CDR battery, you will have 5 options from LG and one from Sony:

LG HB2 1500mAh 30A CDR

LG HB4 brown 1500mAh 30A CDR

LG HB4 mustard 1500mAh 30A CDR

LG HB6 ivory 1500mAh 30A CDR

LG HB6 lavender 1500mAh 32A CDR

Sony VTC3 1500mAh 28A CDR

All are limited to 1500mAh capacity.

Many misinformed people believe all the Sony VTC batteries are 30 amps. The Sony VTC4 2100mAh is a 23 amp CDR battery and the Sony VTC5 2600mAh is a 20 amp battery according to Battery Mooch's bench tests. List of Battery Tests

As a side note, don't fall for the inflated ratings of those "rewrap" battery companies.

Everything Baditude said. And buy from a reputable dealer such as IMR rather than eBay or Amazon. There are lots of counterfeits out there, and it's not worth trying to save a few dollars and buying a substandard battery.
