AA to 18650 / LR6 to 18650 battery adapter converter holder
Description
AA to 18650 / LR6 to 18650 lithium ion battery adapter holder. Enables an AA battery to fit into some slots designed for 18650 batteries. Designed for an 18650 battery compartment which has a spring on the negative, but may work on other types. Why? Some things that run on an 18650 can run on a single AA battery. Sketchup file included for you to customise. How to make it: 1. Buy the AA terminals (Google terminals battery shrapnel AA or AAA battery spring positive and negative) See images for the dimensions of the ones I used 2. Print the thing. No supports is fine, you will just have to remove a small amount of plastic on the underside 3. Insert and bend tabs 4. Solder (Quickly, if it's PLA you are using)
