Battery Spacer (3 x 18650) Cap Radiating Cell Holder

Description

Build safe, professional, and structurally sound custom power packs with the interlocking Battery Spacer (3 x 18650) Cap. This premium electronic component is engineered specifically to secure and isolate cylindrical 18650 lithium-ion cells inside high-current battery packs. Designed with flame-retardant industrial materials, these cell holders feature high temperature resistance and excellent heat dissipation, keeping your custom power banks cool during active charge cycles. The smart interlocking modular edges allow you to smoothly scale and slide multiple units together to form larger matrices for electric vehicles, solar storage systems, or high-capacity power supplies. You can easily connect this hardware grid to your favorite microcontroller platform. To build your next autonomous mobile robot or remote power tracking project, check out our compatible Arduino development boards.

Features

• Modular Interlocking Edge Rail: Features standard slide-and-lock tabs on all sides, enabling easy expansion into any custom matrix size (e.g., 2×4, 4×10).

• High Efficiency Thermal Air Gap: Safely creates structural physical spacing between cells to optimize airflow and prevent localized thermal runaway.

• Premium Mechanical Impact Strength: Protects delicate cylindrical cells against external drops, vibration, and shifting inside your enclosure.

• Flame-Retardant Material Base: Molded from heavy-duty industrial plastic that stands up to heavy spot-welding temperatures without cracking or melting.

• Standard Nickel Strip Guide Rails: Formed with structural top and bottom clearance paths to accommodate nickel strips seamlessly for safe spot welding.
