Converted an old flashlight to LED and also changed the three C size batteries with two 18650 in parallel. As the 18650 aren´t the same size of a C size battery I made this adapter.
The height of two adapters is a little shorter than 3 c size batteries, but worked great because the LED filled the missing space.
It has holes and slots for wires, can be used in series or parallel as needed.
I just glued them with super glue and the flashlight is working great and lasts forever!
