Unfortunately no one informations there about max voltage . Stay with AA rechargeable better.
“The HyperCAGE features an industrial design that is nearly unbreakable. Drop it from 100 feet and dunk it 3 meters under water, it can handle it.”
It survives a 100 foot drop. That’s impressive!
That is reason I own 2 of them. Just wanted to use 14500. But I will settle on Eneloops if not viable for 14500.
For 14500 buy this and you will be more than happy:
I got several 14500s now.
The Sofirn 14500 is noticeably shorter, even with its button top, it’s just as tall as the shoulder of the Fujitsu (LSD NiMh).
The Hixon is a protected 14500 and is notably much taller than a regular AA (it’s also slightly fatter in diameter).
The PKCell is a flat-top (on the second PKCell in the picture, I placed a disc magnet on top of it so it can function as a button-top temporarily on flashlights that require button tops)
