I bought a L7. I also bought the extenders to use 26800 batteries. But I can’t make them work.

The batteries work in other flashlights, including my M26D .And the flashlight works with the 26550s that were shipped with it.

I’m using the button disks between the batteries and in between the top battery and the head, same as with the 26550s.

It’s almost like they’re just isn’t electrical connection being made from the tail switch through the extenders and the body.

Anybody else deal with this?
