Smallest tube mod that will stand?

[six]

I find myself using my map tanks a little more often lately. I have a couple of really big 18650 tube mods that stand up, but I want something with a lower center of gravity and lower profile so I can quit knocking it over. My rough stacks are fine but for having to use a 510/510 battery extender for the MAP which increases the height (the shorty 510/510 works but doesn't leave nearly enough room for comfortable button operation).

What's the smallest tube mod that will stand on end without easily tipping over (besides the rough stack)? Bottom or side mounted button is probably fine. This will likely be exclusively for tank mod use.

I like the size of my Provari and I dont find it is top heavy with my MAp tank at all.I uses an 18490 but has the technology to convert the 3.7v to 6v.If you wanted to use your 18650 batteries they make an extension bottom cap but Im not sure that would keep it short enough for your needs.

I believe the bb will stand up and its fairly small. Uses a 14500 batt. Check it out at altsmoke

The darwin will lay completely flat on the table with the map tank standing straight up....lowest profile you will find....

The SP2 is small. It uses 16340 batts.

I didn't even think about that. retird is right that woud be a very low center of gravity option.
