MM 20/21700 Battery Tube


Product Description



Made from brass or SS 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.

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
