SPIDER Automation | 2-Slot 18650 Battery Holder with DC 2.1mm Power Jack | 7.4V Nominal Series Battery Connection
Product Overview & Battery Holder Design
SPIDER Automation 2-Slot 18650 Battery Holder with DC 2.1mm Power Jack provides a convenient way to accommodate two compatible rechargeable cells and supply power to electronic circuits. Its two-cell arrangement connects the batteries in series, combining their individual voltages to provide a higher nominal output than a single cell.
When two compatible 3.7V nominal 18650 cells are installed, the series configuration provides approximately 7.4V nominal output. The actual voltage varies according to the cells’ chemistry, charge condition and operating state. The holder is intended for use with compatible cells; battery compatibility and polarity should be verified before installation.
The holder includes an integrated DC 2.1mm power jack, allowing connection to equipment and development boards that support this connector and the supplied voltage range. Its 100mm wire length provides the connection between the battery compartment and the output jack.
The black housing features mounting holes for installation into suitable enclosures and equipment assemblies. With an overall size of 93 × 57 × 15mm, it offers a compact mounting format for compatible battery-powered electronics. Batteries are not included in the package.

Installation & Usage Recommendations
- Verify Cell Compatibility: Confirm that the holder physically accommodates the selected cells before installation.
- Check Cell Polarity: Insert both cells according to the polarity markings and verify the output polarity before connecting equipment.
- Use Matching Cells: For a series battery arrangement, use compatible cells with matching chemistry, nominal voltage, capacity and condition.
- Check Device Input Requirements: Confirm that the connected board or circuit supports the actual voltage range produced by the selected cells.
- Use Appropriate Charging Protection: Remove cells for charging using a compatible charger, or use a properly designed two-cell charging and protection arrangement. Do not charge cells through the holder unless the complete charging configuration is confirmed as suitable.
- Observe Temperature Limits: Follow the specified maximum operating temperature of 80°C and avoid exposing the holder to unsuitable heat.
