I'll put it down to psychological effect. There's no way that vapour and taste will be different due to a different battery in a REGULATED mod. Mechanical, yes, the batteries will make a difference.
But, I've been wrong before. So, there's that.
I do agree that it is psychological effect. the only diff to tell is using mech mod which I had not.
Will try out this evening see how is the vape
AW 2000mah the discharge is 10A and the 1600mah discharge is 20A (read from the website) on using mech mod, 1600 lasted me shorter timing but the firing is good
The only way is to compare the battery is on the mech mod. DNA / DNA clone harder to tell due to regulated power.
I uses VTC4 and AW 2000 and AW 1600 on the clone DNA but felt VTC4 is the better one after the Efest
On Mech Mod, I still prefer using AW, it give me constant firing for quite some time till the batt looses it energy ha ha!
