SPIDER Automation | 18650 3×3 Battery Cell Spacer Holder | 9-Cell Modular Battery Pack Support
Product Overview
The SPIDER Automation 18650 3×3 Battery Cell Spacer Holder is a modular battery assembly component designed to organise and support cylindrical 18650 lithium-ion battery cells. Its 3×3 arrangement provides nine individual cell positions, helping maintain an organised layout and consistent spacing during the construction of multi-cell battery packs.
Manufactured from ABS material as listed in the product specifications, this spacer holder features an 18.5mm bore diameter to accommodate compatible 18650 cells. Its edge-interlocking design allows multiple holders to be connected, making it possible to create different battery pack dimensions and configurations according to the mechanical requirements of the project.
The open, radiating structure supports airflow around the cylindrical cells and is suitable for battery pack designs where cell arrangement, spacing and thermal considerations are important. It can be used in e-bike battery assemblies, custom lithium-ion battery packs and other 18650-based energy storage projects.
Technical Features & Construction
- 3×3 Battery Cell Arrangement: Provides nine individual positions for organising 18650 cylindrical battery cells.
- 18.5mm Cell Bore: Designed around the specified bore diameter for compatible 18650 cells.
- Modular Edge Slots: Interlocking slots along the holder edges allow multiple spacers to be joined together.
- ABS Construction: The supplier’s specification table identifies ABS as the holder material.
- Open Radiating Structure: The spacer design leaves open areas around the cells to support airflow through the battery assembly.
- Flexible Pack Layout: Multiple holders can be combined to create different battery pack sizes and shapes.
- Structured Cell Positioning: Helps keep cylindrical cells organised during battery pack construction.
Modular Design & Battery Pack Assembly
The holder incorporates interlocking slots along its outer edges, allowing compatible spacers to be connected into larger assemblies. This modular arrangement provides flexibility when designing battery packs with different cell counts, dimensions and mechanical layouts.
The 3×3 configuration provides a structured starting arrangement for a nine-cell group. Additional compatible holders can be integrated to build larger battery assemblies, subject to the required pack geometry and available installation space.
- Custom Pack Geometry: Supports the construction of different battery pack shapes and arrangements.
- Interconnected Structure: Edge slots help connect compatible spacer holders.
- Organised Cell Placement: Maintains a defined layout for cylindrical battery cells.
- Flexible Integration: Useful for prototypes, customised battery packs and application-specific assemblies.
Radiating Structure & Functional Advantages
Battery cell arrangement plays an important role in the mechanical and thermal design of a battery pack. The holder’s open spacer construction creates space around the cylindrical cells, supporting airflow through the assembly compared with a fully enclosed arrangement.
- Airflow Support: Open spaces around the cells allow air to circulate through the battery arrangement.
- Consistent Cell Spacing: Helps organise cells in a defined 3×3 layout.
- Mechanical Organisation: Provides a structured framework for battery pack assembly.
- Modular Expansion: Interlocking edges support the integration of additional holders.
- Assembly Flexibility: Suitable for customised battery pack dimensions and configurations.
- Compact Arrangement: Helps organise multiple cylindrical cells within a planned mechanical layout.

Connection & Operating Recommendations
Use this spacer holder as a mechanical cell-positioning component during the construction of compatible 18650 battery packs. Confirm that the battery cell dimensions are suitable for the specified 18.5mm bore diameter before assembly.
- Cell Compatibility: Use compatible 18650 cylindrical cells with dimensions suitable for the holder.
- Pack Layout: Plan the required cell arrangement and overall battery pack dimensions before assembling multiple holders.
- Interlocking Assembly: Align the edge slots carefully when connecting multiple spacer holders.
- Electrical Connections: Use suitable nickel strips and a battery-pack welding process appropriate for the selected cells and pack design.
- Thermal Design: Consider airflow, heat generation and the operating environment when designing high-current battery packs.
- Pack Protection: Select an appropriately rated BMS, protection system and wiring based on the battery chemistry, series/parallel configuration and intended load.
- Mechanical Security: Ensure the completed battery assembly is adequately secured within its enclosure or mounting structure.
- Safe Assembly: Follow appropriate lithium-ion battery handling, insulation and short-circuit prevention practices during construction.
