Product Overview
CB-18650-PC2 single-cell 18650 battery holder with pre-attached red (positive) and black (negative) wire leads terminating in bare stripped ends. Black polypropylene housing, UL94V-0 flame rated. Nickel-plated 302 stainless steel spring contacts at both ends. Dual integrated mounting holes on the base for screw or chassis mounting. Designed to accept one 18650 lithium-ion cell and connect it to a circuit via soldered wire - no PCB footprint required.

Applications
- Hardware developer wiring an 18650 cell into a chassis-mounted enclosure without a PCB footprint - strip the leads, solder to your power module, done
- DIY power bank builder using a TP4056-based charger board who needs a safe, repeatable way to connect and swap cells without soldering directly to the battery
- IoT prototyper needing a single-cell supply rail on a bench or enclosure mockup before committing to a board-mount design
- Maker or homelab builder adding portable 18650 power to a custom project - robotics, wearables, flashlight mods, or anything that runs on a single lithium cell
Frequently Asked Questions
What type of 18650 battery fits this holder?
Designed for a protected, button-top 18650 Li-ion cell. Protected cells include an integrated protection circuit and are typically 1-2mm longer than unprotected flat-top cells. Standard unprotected flat-top cells may not make reliable contact with the spring terminals.
Is a battery included?
No. The holder only is included. Battery is not included.
How does this mount - does it need a PCB?
No PCB required. This variant has pre-attached wire leads and dual mounting holes on the base for screw or chassis mounting. Solder the bare wire ends directly to your circuit. The standard BK-18650-PC2 uses rigid PC pins for through-hole PCB mounting - this CB-18650-PC2 is the wire-lead variant intended for chassis or external wiring applications.
How much clearance is needed above the mounting surface?
21.4mm above the mounting surface for the holder itself. Account for the loaded cell height as well when sizing your enclosure.
Getting power from an 18650 into your project should not be the hard part - solder two wires, screw it down, snap in a cell. The holder does its job quietly so you can get on with the build that actually matters.
