Battery holder for 1× 18650 cell, No name LX3214

Single-cell 18650 battery holder (No name LX3214) designed to secure one 18650 lithium-ion rechargeable cell. The holder provides a compact and practical mounting solution with clearly separated positive and negative contacts and insulation to reduce the risk of short circuits. Its form factor allows a removable 18650 cell to be used for DIY electronics, battery packs, flashlights, testers and prototyping where an easily replaceable power source is required.

Advantages

The holder offers simple and stable retention of a single 18650 cell, with accessible contact points for soldering or clip connections. Its insulated body reduces accidental contact between terminals and surrounding conductive parts, while the compact size saves space in enclosures. The design supports quick battery replacement without soldering the cell directly, improving maintenance and testing workflows.

Suitable for

• DIY electronics projects and prototypes
• Custom battery packs and power banks
• Flashlight assemblies and portable lighting
• Battery testers and measuring equipment
• Educational electronics and hobbyist kits

Key specifications

• Cell format: single 18650 lithium-ion rechargeable cell
• Contact arrangement: separate positive and negative terminals
• Material: insulated plastic housing with metal contacts
• Mounting: panel or chassis mounting footprint (compact form factor)
• Connection method: solder pads or wire solder points on contacts
• Compatibility: standard 18650 cell dimensions

How to use

Insert the 18650 cell into the holder aligning the positive and negative ends with the marked contacts. Ensure the cell sits firmly and that the contacts make solid electrical connection. Secure the holder in your enclosure or on a chassis using suitable screws or adhesive as required by your design. Make wiring connections to the holder's terminals using soldered wires or connectors compatible with the contact pads, and verify polarity before powering your circuit.

Usage recommendations

Use only undamaged, properly rated 18650 lithium-ion cells and observe correct polarity when inserting the battery. Avoid exposing the holder to high temperatures or mechanical stress that may deform the housing or contacts. For permanent installations consider additional insulation and strain relief on wires; for testing or prototyping, ensure good contact and periodic inspection to maintain safety.
