Getting tired of reading stuff with capital letters and " I HAVE TESTED x and y " ... post some graphs to show the tests.
Regarding the 900mah greys, it's the biggest capacity 18350 out there, and my vmax v2 runs for 15-20% longer on those, i can't feel the power difference between those and AW , i mostly use Sailing Technology 306 2.8 ohm atomizers at ~5v setting on it ( = 1.78 Amps from TWO stacked batteries , in the case our beloved vmax would actually work at the set voltage, so let's say it's 5,5v tops wich would be 1,96 Amp draw, again pulled from TWO batteries ).
The only batteries with wich there's a significant difference in power is with random 16340s wich we know even top brands don't get to 600mAh.
A situation in wich IMR high-drain power would be usefull is if you vape dual coils at high voltage. Even 1.5 dual coil (wich is 2x 3ohm coils ) at 6v you're not drawing more than 2-2.1 amps from one of the two cells, and most people vape their 1.5s at 5v = 1,66 amps drawn from a single cell. Discharge capacity is in general 2C for li-ion wich means 1,8 Amps from the 900mAh battery.
@Random85 : the batteries in the picture would definitely not be recommended, i can provide you with pictures of mine if needed, to show that they indeed have insulation jacket on the bottom.
VAPN350 : try some of the 900 ones ( definitely with insulation jacket on the bottom ), test them out.
It's an alternative. If you haven't tried them, no use to regard them as crappy.
I have no love for particular brands. AW cells come mostly from panasonic, but not for all models. Their 16340 protected can be considered crap for example, it rarely gets above 550mAh capacity, let alone the 750 claimed.
Sanyo 2600 performs just as well as the AW 2600 for a fraction of the price. For a dual 18650 vv mod you can have 3 sets of TF 18650 "flames" resulting in 7000-7200 total mAh for the price of a single pair of 2900-3050 AW "3100", and so on..
There are no charts, no detailed tests on EFEST on the internet, when somebody goes looking for them all that comes up is VAPN350. It would help a lot of people if there were some further details/graphs.
