Got a GLV!!!

[bypassoverload]

I have been wanting to try a mod for sometime now and have had my eye on the GLV.
I managed to pick up a GLV-2 Mini on the classified here.
Few questions.
Is the glv-2 and glv-3 the same except for the feeder box? Could I order the feeder box and use it with my glv?
I am a moderate to heavy vapor, how long can I expect to get off of the recommended 16340 batt?
Here she is...

I get about 3/4 of a day out of my batteries (I'm using the AW IMR). I use 1.5 ohm 901 attys and drip 100% VG

Thanks again Ross for the smooth deal.
If you vape throughout the day I recommend at least have an extra 16340 battery with you.
I do hope she serves you well as she did me.
