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!
Only need to be carefull to not overdischarge the 18650s
This can be used in other projects aswell
