Harbor Freight Flashlight Upgrade - but why?

[atatistcheff]

Weekend project, "upgrade" my free Harbor Freight flashlight from 3x AAA to 1x 18650. Includes USB charger module.

I'm not saying this was a good idea, just something to do. Still need to find some longer screws to put it all together.

Parts are:
- 18650 battery
- some nickel strips
- wire
- charger module: https://www.ebay.com/itm/5V-1A-1S-3...ry-Charging-Module-Charger-Board/322366742192

Because everything needs a lithium battery!

Cool project! I might try this from parts from dead single cell and multi cell power banks.
