Description
Designed this to be able to use 18650 batteries with my flashlight. It is suitable with the flashlight in the picture. If you have similar flashlight you can give it a try.
All you need is some foil then apply steps in the pictures.
The on/off button side might be tight so turn it a few times to make it get used to its place.
!!! Be careful !!!
The flashlight i have has negative line on the body that means if positive side of the battery touches somewhere inside or outside it is going to cause shortcut.
Shortcut may cause the battery to reach high temperature and get damaged.
