magnum mod 3.7v vaping battery?

[breakdown00]

i have a mag mod i just got and it came with 2 ultrafire 3.0 CR2s but those batteries really dont last a super long time, tho once i get the second set it will be pretty easy, nonetheless i was wondering what battery to use for "normal" voltage as in the same volts a regular 510 battery puts out which i assume is 3.7v. also a link would be great (to deal extreme) and how long it would last roughly

A 3000mAh 18650 battery should last you at least two days if you're a heavy vaper.

And if you don't want to wait for the slow boat from China, here is a Battery Junction link. It's still pretty cheap, and shipping is a whole lot faster.

Sorry, misread.

Battery Junction has those, too. Just in case you need some fast and don't want to wait 2-3 weeks to get them. http://www.batteryjunction.com/ultrafire-18500.html

Can't beat the prices on the ones from China, though.

The numbers denote size. The first two numbers are the width in mm, the next two are length in mm, the last "0" just means it's cylindrical.

You can get 18650 batteries in 3000mAh, which lasts a long time. 18500 batteries go up to around 1600mAh, meaning they'll last about half as long, with the same usage.
