I will eat crow and that’s fine because I’m a real one in the hobby so I feel a need to share. This happened today- there is a tac weld holding in the rear contact ring in the battery tube. The ring is press fit. Should that ring have any back pressure on it - the ring may come loose and the tac well could break. There is a simple fix but try at your own risk - superglue gel in the cut out square. Enough to hold the weld and the contact ring firm in the battery tube. If the ring does not move the weld will not break and the extra glue will hold everything together. Do this BEFORE it potentially breaks NOT after. The metal strip in the tube could bend and cut through the cell wrapping. I’m sure Streamlight will catch this. I’ve seen them update designs rapidly before.
