1x 18650 Battery Holder, 18.4mm Bore Diameter (2-Piece Pack)

Soldering tabs directly onto a lithium cell is both risky and hard to undo later, and this single-cell holder avoids that entirely with spring-loaded contacts that grip a standard 18650 cell securely while giving a project solder points or wire leads to connect to instead. Its 18.4mm bore matches the standard 18650 form factor, and the included pair means a project can mount two separate single-cell holders, useful for builds that want independently swappable cells rather than a fixed multi-cell pack. It is a basic but essential building block for any custom 18650-powered project, from flashlights to small robotics battery packs.
