Screw Lid 21700 Battery Holder


This single 21700 battery holder is designed to withstand serious abuse! It is printed from strong PETG to prevent dents or damage to your battery. The flexible retainer strap prevents the lid from getting lost.

Mystery colors are available in unique combinations of the fluorescent and translucent colors shown in photos below! A unique color for the cap and body will be randomly selected for the mystery color.

These battery holders work with unprotected flat-tops and button top cells without built-in charging only. Batteries with significantly wider bodies than 21mm and longer than 70mm will not fit.
