3x5 Cell 18650 Batteries Spacer

Compact 15-Cell Matrix Layout: Pre-formed 3 x 5 grid structure securely mounts up to 15 standard 18650 cylindrical lithium-ion cells in a clean, rigid alignment.

Modular Interlocking Snap-Fit Edges: Designed with peripheral dovetail clips along the edges, allowing multiple 3 x 5 grids to snap together to build larger custom pack dimensions (e.g., 6 x 5, 3 x 10, or extended matrix arrays).

Passive Thermal Ventilation Channels: Maintains exact, uniform spacing between adjacent cells to establish vertical airflow channels, facilitating passive heat dissipation and preventing thermal pooling.

Cell Isolation & Short-Circuit Prevention: Keeps individual cells firmly isolated to eliminate sleeve friction, structural twisting, and accidental short circuits across high-drain power arrays.

Flame-Retardant ABS/PC Construction: Molded from high-impact, heat-resistant ABS/PC composite plastic (UL94V-0 rated) that resists mechanical shock and high operating temperatures.

Spot-Welding & Bus Bar Friendly: Features wide open top and bottom access ports designed specifically to streamline spot-welder probes and 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: 3 x 5 (15 Cells total).

Color: Matte Black.

Usage Advice: Snap multiple 3 x 5 blocks together as needed to match your custom battery enclosure before inserting 18650 cells and spot welding.

Maintenance: Keep grid slots clean and free of dust or flux residue; inspect locking tabs during routine pack servicing.

Essential Medium-Capacity Pack Staging Matrix: Position as a versatile pre-formed grid for medium-sized power tool battery rebuilds, custom e-bike battery modules, solar backup blocks, and DIY power banks.

Highlight Compact Pre-Formed Layout & Modular Expansion: Emphasize how the 3 x 5 block speeds up bench assembly over individual brackets while preserving full expansion flexibility via snap-fit connectors.

Recommended Cross-Sell Add-ons: Pair with 5x5 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.
