Made from brass with copper solder tabs and copper positive connection giving you the best contact material.
This tube is made big enough to take 20700 and 21700 flat top batteries.
iJOY 21700 batteries are too wide for this tube. They seem to have re-wrapped batteries that are around 21.5mm diameter.
Samsung 30T cells fit perfectly inside these tubes.
Please measure your battery to make sure it is under 21.4mm diameter so it fits inside these tubes.
The negative and positive solder tabs makes it easy to connect your wires and the bottom caps have finger holes and a coin slot for tightening.
A little more expensive than some but there are more machining processes, extra parts, improved cap and a nice finish on these tubes.
Total Length: 84mm
Tube Length: 79mm
Diameter: 24mm +- 0.1mm
Please note that because these are made from natural brass they may come with some discoloration but they will polish up to a uniform shine pretty easily.
