5x5 Cell 18650 Batteries Spacer

High-Density 25-Cell Array Staging: Pre-formed 5 x 5 matrix securely holds up to 25 standard 18650 lithium-ion cylindrical cells in a unified, high-density block layout.

Modular Interlocking Edge Extension: Built with peripheral dovetail joints, allowing multiple 5 x 5 grids to snap together seamlessly into massive 5 x 10, 10 x 10, or custom high-capacity battery banks.

Optimized Thermal Air Gap Spacing: Holds cells at exact intervals to create uniform vertical air channels across the entire 25-cell block, facilitating passive heat dissipation during high-discharge cycles.

Strict Electrical & Physical Isolation: Prevents cell-to-cell contact, friction, and structural twisting, ensuring absolute insulation against short circuits across heavy power tool arrays, EV packs, and solar walls.

Flame-Retardant ABS/PC Construction: Molded from high-impact, heat-resistant ABS/PC composite plastic (UL94V-0 rated) that maintains physical integrity under high operating temperatures.

Spot-Welding & Nickel Strip Alignment: Features open top and bottom access ports designed specifically to streamline spot-welding probes and 2P/multi-P nickel strip bus bar alignment.

Housing Material: Flame-retardant, high-impact ABS/PC composite plastic.

Technical Specifications:

Cell Compatibility: Standard 18650 Cylindrical Lithium-Ion Cells (18mm diameter).

Matrix Capacity: 5 x 5 (25 Cells total).

Color: Matte Black.

Usage Advice: Align and snap multiple 5 x 5 spacers together to match your battery enclosure dimensions prior to inserting cells and spot-welding nickel interconnects.

Maintenance: Keep grid slots free of dirt, solder flux, or metallic debris; inspect interlocking tabs during routine pack servicing.

Essential High-Capacity Pack Staging Matrix: Position as a foundational staging grid for large-scale energy storage systems, solar battery walls, electric vehicle power packs, and heavy-duty power tool rebuilds.

Highlight High-Density Capacity & Modular Expansion: Emphasize how pre-joined 25-cell blocks dramatically speed up bench assembly times while offering infinite expansion through snap-fit side connectors.

Recommended Cross-Sell Add-ons: Pair with 3x5 Cell 18650 Batteries Spacer, 18650 Lithium Cell Battery Holder Bracket, 1M Pure Nickel Strip 2P for 18650 Battery Pack, and ESD antistatic mat 50x40CM PCB Welding Mat.
