HI and welcome. What battery I shall recommend is going to be greatly dependent upon what wattage you want to vape. This is also true regarding battery life; you have a much better chance of making it through the day at 13 watts than you do at 213 watts. Here's a copy of our resident Battery Jedi, Mooch, latest selection chart:
I won't get all technical regarding how to calculate the amp draw on a regulated mod, but a good rule of thumb 60 watts per cell for 20amp batteries. Your Revenger is a two-battery mod, so 20 amp batteries should allow you to safely vape up to 120 watts. On the chart, the battery with the greatest storage capacity is the Panasonic/Sanyo NCR18650GA, but
this is only a 10 amp battery. If you know you are never going to vape above 40-50 watts (never, never, never, ever, never; I promise. Cross my heart and hope to blow my face off with an exploding battery if I cheat. Seriously.) you can't beat those for battery life. Even then, I still don't recommend it, simply because you mod can be set above the max wattage and slips happen. Those Sanyos are for Old Skool Provaris that can't make over 15 watts on their best day. Under 120 watts I'd go with the Samsung 30Qs, which are solid 20A batteries and have 3000 mAh, the best 20A battery on the chart. If you can tolerate a bit less wattage-- say, under 100 watts-- then the LG HG2 (18A) and the Sony VTC6 (19A) are both sound cells with similar battery life characteristics; and which might be cheaper. I use the HG2 "poop stick" batteries in my 3-battery mods, of which I have several.
If you need more than 120 watts, the LG HD series (HD2, HD2C, HD4) are good for 25 amps and will take you into the 150 watt range. I use the HD2Cs and Sony VTC4s (getting hard to find) in my mech mods to provide better safety margin.) Above that, I'd go with the LG HB series at 30A out to 180-200 watts. If you really need more than that, ditch the Revenger and get a 3-4 battery mod; possibly considering a 3S or 4S LiPo pack custom rig.
Finally, note the blue section at the bottom with "trusted vendors." Buy your batteries from one of them. There are counterfeits out there.
