fenix battery adapter
"this makes the 18650 fit much better in a 21700 flashlight with out it moving around ."
Good Option
"Not cheap, but a good option to enable you to use more widely available 18650 batteries in your 21700 light."
Q&A
- Will this adapter work okay with an 18500 battery to replace a [3] AAA battery carrier in a flashlight?
- No, it is strictly meant for 18650's
- Will this fit two CR123 batteries?
- While they may fit, that is not what is meant for. It is meant to put an 18650 in, to use as a 21700 and is not meant to do anything except what it was developed for.
