18650 Battery Holder – Secure Mount with Contact Slots

Loose 18650 cells rolling around your workbench, rattling in a drawer, or getting lost in a parts bin — it's a small annoyance that adds up fast. This compact battery holder keeps a single Li-ion 18650 cell locked in place, with pre-cut slots for metal contacts and mounting holes so you can fix it exactly where you need it.

How it solves the problem

Whether you're building a custom power bank, wiring up a flashlight mod, or prototyping a battery-powered circuit, you need the cell held securely while contacts stay aligned. This holder does exactly that — no improvised tape, no foam wedges, no fumbling. The contact holes are sized for standard metal terminals, and the mounting holes let you attach it to a panel, project box, or surface without any extra hardware gymnastics.

• Precise contact cutouts for standard 18650 terminals
• Mounting holes for screw or rivet attachment
• Snug fit holds the cell without crushing or slack
• Compact footprint — fits inside enclosures and project boxes
• Works with flat-top and button-top 18650 cells

Where it shines

This holder earns its place in DIY electronics projects, battery-powered builds, repair benches, and anywhere you're working with 18650 cells regularly. Fix it inside a custom enclosure, mount it to a test rig, or use it as a stable base while you solder contacts — it handles the holding so you can focus on the work.

It also works well as a storage solution if you're keeping charged and discharged cells separate on the bench. One holder, one cell, clearly positioned — no mix-ups.

The setup

You receive the holder ready to go. Drop in your 18650 cell, align your contacts through the slots, and fasten it down through the mounting holes. No assembly required beyond installing it in your project. Clean, minimal, functional — exactly what a good component holder should be.
