it depends. You are using 5 amp test. At 4 volts that is 20 watts. Not to many people vape at 20 watts??? I vape between 5 and 8 watts, because anything more I get a bitter taste.
so it depends. Take the bat's that did well at 5 amps and compare to a high mha bat at 1.5 and 2 amps and they both will perform well, but the high mha batt will out live the the 1600 mah batt by 50%.
So it depends un how may amps or watts you will be drawing?
