Good selections. I give serious consideration to the
Sigelei Zmax V3 Telescopic flat top. The electronics do pretty much the same job as the Vamo but the battery choices are a lot broader with the Telescopic. I find myself using 18500 during the day and 18650 at home. 18350 is a small battery but it just doesn't last me more than four hours. YMMV. The Sigelei build quality and one-button menu are big attractions for me.
Trustfire TR-001 is a decent charger. At 500mA it won't heat the
batteries a lot. I'd look at the XTAR WP6 II charger. It will charge six batteries at once. Batch charging is a time saver, especially if you are using 18350s.
Smoktech or Boge XL single coil cartos are both good choices and 3.0 ohms will give you a large range of power choices with VV/VW.
A glass
tank from
IBTanked is a nice upgrade from the Smoktech tank. The 19mm XL tank will hold about 2ml of juice in additon to the juice in your carto. The tank kits include an excellent tool for mounting and filling cartos in tanks.
I like the
Siam Mods V2 carto punch from Phiniac, who make beautiful carto tanks.
As you can see, I don't buy all of my gear from one vendor alone.
