SV Battery Tubes 21700 / 18650 / 18350

Stealthvape Battery Tubes (21700 / 18650 / 18350).

We’re pleased to bring your our take on the classic battery tube.

After over two years of development, with numerous design changes and tweaks, we are proud to bring you what we consider to be the ultimate battery tube for modders. These tubes are outstanding quality and incorporate many innovative features which make installation and implementation a breeze. They feature a novel top cap to allow for direct horizontal soldering to minimise voltage losses whilst saving valuable space.

Tubes are available in either 18650 or 18350 sizing.

Notable features:

• High quality SS304 tube stock.
• Tube tolerance +/-0.05mm.
• RoHS tinned brass top cap and centre pin.
• Nickel plated brass battery cap.
• PEI (Ultem) insulator.
• Unique vertical mount direct soldering for minimal losses.
• Battery cap designed by Filip Visnjic from Cloud Laboratory

Please choose your size option from the drop down menu above.

21700 top cap has a reduced mass to make soldering those fat 14g wires easier

Soldering Options

The battery tube connector cap is extremely versatile, allowing multi-directional wiring. The easiest method to solder the wires in place is to use pre-tinned wire, use a little flux on the wire first, then just solder direct using plenty of solder. Thermal mass shouldn’t be an issue (depending on your soldering iron), but its better to use more heat and less time rather than a lower temperature and dwelling too long.

We also offer a battery tube laser etching service. For full details please see here.
