Hi guys so I've narrowed it down to these two battery's for my first VV, but I'm stuck between trying to choose between them. The box mod kind of scares me. I've also seen reports that they fire about the same ratings. But another thing is the weight difference. Yes it would be nice to be able to charge things but the MVP2 would be so much heavier. Then again I could probably go a week without charging knowing my vape habits (only changed my 900 ego batt once in the week I've had it). I am female and do have a large purse usually so not as much of an issue for carrying. So I'd love to hear personal opinions on these two batteries. While the price difference of 20 bucks might not seem like much to some, it's a lot of money for me to spend on a new battery when I have Christmas and a new cute boyfriend to spoil. So if I'm going to spend that extra 20 I want to be sure it's worth it I guess.
