SPIDER Automation | 18650 3×6 Battery Cell Spacer Holder | 18-Cell Modular Battery Pack Support
Product Overview
The SPIDER Automation 18650 3×6 Battery Cell Spacer Holder is a mechanical battery spacing component designed for organising 18 cylindrical 18650 lithium-ion cells in a structured 3-row × 6-column arrangement. It helps maintain the relative positioning of individual cells during the construction of custom multi-cell battery packs.
The spacer features an 18.5mm bore diameter for accommodating compatible 18650 cells and incorporates interlocking slots along its edges. These slots allow compatible spacer units to be connected to create different battery pack shapes and mechanical arrangements.
Its spacing-oriented structure is intended to support organised cell placement and provide room for airflow around cells, depending on the final battery pack design. It can be used in custom battery assemblies such as e-bike battery packs, portable power systems and other cylindrical lithium-ion battery projects.
Technical Features & Construction
- 18-Cell Arrangement: Provides 18 battery positions in a 3-row × 6-column configuration.
- 18650 Cell Compatibility: Designed for cylindrical 18650 lithium-ion battery cells.

Modular Design & Battery Pack Assembly
The spacer incorporates slots along its edges that allow compatible units to interlock with one another. This modular arrangement provides flexibility when designing battery packs with different cell counts, dimensions and physical layouts.
- Expandable Battery Layouts: Multiple compatible spacer units can be connected to form larger battery pack structures.
- Flexible Pack Configuration: Supports different mechanical arrangements for custom 18650 battery assemblies.
- Structured Cell Positioning: Helps maintain an organised 3×6 cell arrangement during assembly.
- Mechanical Assembly Support: Provides spacing and positioning support for cylindrical battery cells.
- Custom Pack Development: Suitable for battery pack prototypes and application-specific mechanical layouts.
Thermal Management & Mechanical Support
The spacer is designed to maintain spacing between adjacent cylindrical cells, helping create potential airflow paths within the battery assembly. This arrangement can be useful in battery pack designs where heat dissipation and cell positioning are important considerations.
- Cell Separation: Helps maintain spacing between neighbouring 18650 cells.
- Airflow Provision: The spacing structure can support air movement around cells, depending on the overall pack layout.
- Mechanical Organisation: Helps keep cells arranged in a defined multi-row configuration.
- Modular Construction: Interlocking edges support the creation of larger battery pack structures.
Actual thermal performance, vibration resistance and mechanical stability depend on the complete battery pack design, cell arrangement, electrical interconnections, enclosure and assembly method.
