So I've got myself a pair each of the new LG HB4, HB6, and HD2 batteries. The HB4 is hard to find but it's over the better cell. HD2 batteries aren't that great and don't compare to VTC4s. 30amps is a must.
You should read mooch's bench tests results reguarding this subject....There are no real 30 amp continuous 18650's. Not even the LG HB6. Bench tests have rated the HB6 at the highest at around 27 amps I believe, the Sony's are around 24. The standard is 20-25A, the rating you often see is burst.
As far as which battery 18650 wise is king of high amps, it's the HB6. The Sony's are nice, but the VTC3 would be best for high amps because it has the least internal resistance which leads to less sag = less amps being drawn off of it because it's not working as hard in regulated mods to hit a given wattage unless it's being run through a buck circuit.
The more MaH (capacity) a cell has, the more internal resistance, the more IR, the more sag, the more sag, the more amps get drawn off batteries in boost circuit chips because it's sagging to a lower voltage than it's outputting. Boost ups the voltage by drawing more current off the cell, buck does the opposite.
LG makes some damned good batteries, but Sony's are hit and miss because there's more fakes than real ones out there right now. I'm a Lipo man myself, and not just because I'm an engineer working for a Lipo company. I adore them, but 18650's can still take a damned good beating, just don't push them too hard or you'll end up on the news with E CIGS EXPLODE, BIG TOBACCO WAS RIGHT! as a caption. You're gonna have a bad time if that happens, lol.
