21700 battery spacers are used to align, secure, and organize cylindrical lithium-ion cells during battery pack assembly. These spacers are designed to hold 21700 cells in place while maintaining consistent spacing for safe and efficient pack construction.
The larger diameter of 21700 cells requires properly sized spacers to ensure a secure fit and stable battery configuration during assembly.
Key Features
✔ Precision Fit – Designed specifically for 21700 lithium-ion cells
✔ Consistent Spacing – Maintains uniform distance between cells
✔ Secure Alignment – Keeps cells stable during assembly
✔ Modular Design – Available in multiple configurations (2P, 3P, and grid layouts)
Common Applications
✔ Battery Pack Assembly – Used to build parallel and series configurations
✔ High-Capacity Builds – Ideal for larger battery pack designs
✔ DIY & Custom Projects – Used in lithium-ion battery builds
✔ Prototyping – Helps organize and test battery layouts
Configuration Types
21700 spacers are available in different layouts such as 2P, 3P, and grid configurations, allowing flexibility in pack design depending on your application.
Compatibility
Ensure the spacer is designed for 21700 cells and matches your intended configuration. Some designs may vary slightly based on cell diameter and manufacturer tolerances.
Important Note
Battery spacers provide structural support and alignment only. Proper electrical connections, insulation, and safety measures must be used when building battery packs.
