Last crawled date: 5 years, 10 months ago

Converts a flashlight that uses either 3x AAA sized batteries or 1x18500 for use with standard 18650 lithium ion cells.
Use a nickel strip for the electrical connection (small cable should also work).
The Fusion 360 file has parameters, so that the item can be adapted to different flashlights.
