18650 Steel Battery Tube

Battery tubes are components used in mods in order to house batteries and connect them easily. The contacts (both negative and positive) are connected to the top part of the tube via soldering. Wires proportioned to the type of cell and to the amperage output of the device are highly recommended. The soldering itself is very important to obtain optimal performance from this component: bad, poor quality soldering might affect the conductivity of the circuit. Where applicable, we also recommend to use heat shrinking sleeves to cover the solder area.

The tube and battery cap are made of stainless steel (without scratch proof coating). The battery pin is made of silver plated copper, while the top cap is made of silver plated brass with an array of holes for soldering the negative contact. Insulator is made of Ultem, a type of plastic with great mechanical properties, resistant to heat and chemicals.

Even if this won't affect basic functionality, we recommend you to insert the battery with the positive terminal facing the inner part of the tube (positive toward soldered wires). This way the battery body (which is part of the negative terminal) won't create any short-circuit in case of damaged battery wrapping, because orienting the battery like this the body of the tube will be connected to negative too.

This component can be held in place with a M3 grub screw. No need to glue it, just create a small pocket just in front of the grub screw, then fasten the screw with an allen key from inside the tube. In order to machine the pocket we recommend a T mill of appropriate size. Consider to make the pocket slightly smaller than the grub screw diameter. Using the grub screw fastening is not mandatory.
