18350 USB Rechargeable Battery

Longer than normal 18350 batteries but it's protected, needed that for my Artorch thst doesn't have a battery fuel gauge so I can use it without worry.

Quality seems great but i believe they are out of spec. They are .28mm greater in diameter than my existing 18350’s that are indentical looking :(

Promt delivery and extremely well packaged as with the flashlights i have top quality with performance
