1 Cell 18650 Lithium Battery Holder Case with Wires

The 1 Cell 18650 Lithium Battery Holder Case with Wires securely holds a single 18650 cylindrical battery cell and features pre-attached red and black lead wires for convenient circuit connection. Its open design, polarity markings and mounting hole make it suitable for DIY electronics, prototyping and custom battery-powered projects.

Description

The 1 Cell 18650 Lithium Battery Holder Case with Wires provides a convenient and removable connection for a single 18650 cylindrical battery cell. Its open holder design allows the cell to be inserted or replaced without soldering project wires directly to the battery.

The holder features spring and fixed metal contacts, clearly marked positive (+) and negative (−) polarity positions, and pre-attached red and black lead wires measuring approximately 15–16cm (6 inches). A central mounting hole allows the holder to be secured inside a suitable project enclosure or electronics assembly.

The holder measures approximately 73–76mm in length, 20–21.5mm in width and 17.7–20mm in height, with an approximate weight of 8–10g. It is designed for the 18650 cylindrical cell format, nominally around 18mm in diameter and 65mm in length.

This 18650 battery holder is useful for DIY electronics, prototyping, embedded systems and custom battery-powered projects requiring a removable single-cell power source.

The holder is a passive component and does not provide battery charging, voltage regulation or battery protection. Rechargeable Li-ion applications should use an appropriate charging and protection circuit according to the battery and project requirements.

Technical Specifications

Applications / Use Cases

• Single-cell 18650 battery-powered projects
• DIY electronics and hobby circuits
• Electronics prototyping
• Robotics projects
• Embedded electronics projects
• Portable battery-powered electronics
• Development and testing setups
• Custom rechargeable power projects
• Projects requiring an easily removable 18650 cell

Actual suitability depends on the battery, circuit requirements and intended application.

Compatibility

The holder is designed for one 18650-format cylindrical battery cell.

It can be integrated with compatible battery-powered circuits and, for rechargeable Li-ion applications, an appropriate Li-ion charging circuit such as a suitable single-cell charger may be used according to the cell's charging requirements.

For example, a compatible 18650 Li-ion battery cell can be installed in the holder while an appropriate charging/protection module can be incorporated separately into the project.

The holder itself should not be treated as a charger, protection circuit, BMS or voltage regulator.

FAQs

1.What is a 1 Cell 18650 battery holder?

A 1 Cell 18650 battery holder is designed to hold a single 18650-format cylindrical battery cell and provide convenient electrical connections through attached lead wires.

2.Which battery fits this 18650 battery holder?

This holder is designed for one 18650 cylindrical battery cell, nominally around 18mm in diameter and 65mm in length.

3.Does this 18650 battery holder include wires?

Yes. The holder has pre-attached red and black lead wires, approximately 15–16cm (6 inches) long.

4.What do the red and black wires indicate?

The red wire is associated with the positive (+) connection and the black wire with the negative (−) connection. The holder also has visible polarity markings to assist with correct cell orientation.

5.What are the dimensions of the 1 Cell 18650 battery holder?

The supplied dimensions are approximately 73–76mm long, 20–21.5mm wide and 17.7–20mm high.

6.How much does the 18650 battery holder weigh?

The holder weighs approximately 8–10 grams.

7.Can I use a rechargeable 18650 Li-ion battery in this holder?

The holder is designed for the 18650 cell format and can be used with a compatible rechargeable 18650 cell. The battery and connected electronics must meet the electrical requirements of the intended application.

8.Does this battery holder charge an 18650 battery?

No. This is a passive battery holder and does not contain a charging circuit. Rechargeable Li-ion cells require an appropriate charger or charging circuit selected according to the battery specifications.

9.Does the holder provide battery protection?

No battery protection circuitry has been specified as part of this holder. Where required, suitable battery protection or management circuitry should be incorporated separately.

10.Can this holder be mounted inside an electronics project?

Yes. The holder has a central mounting hole that can be used to secure it in a suitable project or enclosure.
