what voltage?
and yes it uses more then your stock batteries
cause stock batteries are 3.2v NOT 3.7v
shorten your drags. 3-5s is more then enough.
if it tastes burnt maybe its how its wicking for you.
You give very little information for anyone to properly help.
So hit back & let us know exactly what your doing what voltage etc.
Are you dripping or carting?
I use the battery that came with it, one 18650 3.7v protected 3000mAh battery.
When you say, "how it is wicking for you," don't know what that means. I drip, and it really eats up the juice which is OK but about 5 or 6 puffs and it gets that dry burnt taste. Maybe it is the new atomizer???
I love how long the battery lasts (compared to my Joye 510) and it a BIG Improvement over the JoyStick (Never really worked for me a hit and miss on the button), but was hoping there was something I didn't know that would make this one a smoother smoke.
I ordered the Precise by Super-T (Still waiting for it), for away from home and plan to use this one around the house. Will post how I like when I get it.
