With the 2.0 do you use the 3.7V batt? Im thinking it might be because Ive mainly been using the 4.8 NiMh batteries.
Yikes, what flavor are you loosing .... burnt ??
Seriously though, I can't even use the 3 ohm Boge with that battery .... it tastes like ....
I use a lot of Boge 2Ω at 3.7 and I have a serious change in flavor after the first 24 hours.
I don't loose the amount but it changes more to burnt juice. I stick it out if I'm feeling thrifty but like I've said before if I have to use up a buck fifty carto every single day i'm cool with that.
So what I'm really saying is I'm not much help with your situation I guess
EDIT: this is exactly why I honestly tell people that cartos cost much much more for me compared to an atty that I can make last months.
Still love cartos though.
