Excessive slack in Solarforce lights when using 18650

[KevinL]

Has anybody encountered very loose, rattling batteries in the Solarforce L2/L2P series? I am currently using both of them and there is so much excess slack that when shaken along their axis, the battery moves back and forth enough to disconnect the circuit. Multi-mode lights will change modes, single-mode lights will blink. Some cells will not even make contact. I suspect it's both excessive slack (the batteries sit very low in the light) and insufficient springs.



Sure they are nice to play with.....but I wouldn't trust them when the chips are down. They haven't even made it out of my test bench in one piece yet.
