Yes but it depends on what ohms you'll be running? e.g., you want the most mAh you can get for battery life, and if you are running 30w at 1.8ohm, that's only 4amps. If you're doing it at 0.2ohm, that's 12amps so a 10amp battery wouldn't be good. 3100mah is out there, but I'm going to point you towards the samsung 25r 2500mAh at illumn as a known good battery that's got solid battery life at a reasonable cost ($6.50-$7) and should have you covered.
