Battery Cell Spacers

About

Battery cell spacers are used to align, secure, and organize cylindrical lithium-ion cells during battery pack assembly. This category includes spacers designed for 18650 and 21700 battery sizes. These spacers are commonly used in DIY and professional battery builds to maintain consistent spacing between cells, improve airflow, and create stable pack structures for spot welding and assembly. Key Features ✔ Precision Fit – Designed for 18650 and 21700 lithium-ion cells ✔ Pack Building Support – Helps align cells for spot welding and assembly ✔ Consistent Spacing – Maintains uniform distance between cells ✔ Modular Design – Available in multiple configurations (2P, 3P, etc.) Common Applications ✔ Battery Pack Assembly – Used to build parallel and series configurations ✔ DIY & Custom Projects – Ideal for custom lithium-ion pack builds ✔ EV & Energy Systems – Used in larger battery assemblies ✔ Prototyping – Helps organize and test battery layouts Configuration Types Battery spacers are available in different layouts such as 2P, 3P, and grid configurations. These allow flexible pack designs depending on your application requirements. Compatibility Ensure the spacer matches your battery size and configuration. Some spacers are designed for specific diameters (such as 21.3mm or 21.7mm) depending on the cell manufacturer. Important Note Battery spacers provide structural support and alignment only. Proper electrical connections, insulation, and safety measures must be used when building battery packs.
