new to mods help please

Me and a friend was over looking at madvapes. We were wanting to make a 5v using the 510 connecters they have. What size battery box do we need, and what would be the best batteries/battery to roll with.
I am just thinking of using radio shack for the box.
Thanks.

Well there are no 5V Li batts (they are all 3V and 3.7V), so you have a few options...
1) You can use a big 3.7V (like an 18650) and a step-up DC converter.
2) you can use two 3V in series to get 6V, then use a 5V regulator to step it down.
3) I haven't seen anyone doing this, but you may be able to use a zener diode to clip the voltage to 5V.
4) (worst option) you can put a resistor, is series with your atty. Problems with this...It would have to be the correct resistance for any given atty to work out to 5V across the atty...lots of wasted heat energy with a resistor.

There may be other ways

If you haven't tried the hit off a 3.7V 18650 yet, you should try it before you commit to 5V. That battery hits soooo much better than a stock 3.7V batt, that it is plenty for most. And it will last 2-3 days; no 5V setup is going to last 2-3 days.

Just my .02

is a 18650 about the size of a AA? I might just try it that was and look at going to 2. but what would be a good size battery box for that?

AA batteries are 14mm in diameter - look at 14500's ...

Still haven't received my purchase.
Please pm me the tracking number for my order so I can see what the hold up is.
