SPIDER Automation | 18650 3×1 Battery Cell Spacer Holder | Modular 3-Cell Lithium-Ion Battery Pack Support
Product Overview
The SPIDER Automation 18650 3×1 Battery Cell Spacer Holder is a mechanical battery cell support component designed for organizing three 18650 cylindrical lithium-ion cells in a single-row arrangement. It helps maintain the positioning and separation of individual cells during the construction of custom rechargeable battery packs.
Featuring a compact 60×20×8mm structure, this spacer incorporates interlocking slots along its edges. These slots allow multiple units to be connected together to create different battery pack shapes and configurations. This modular construction provides flexibility when designing battery assemblies with different cell arrangements.
The spacer features an open structural design that allows airflow around the cells when incorporated into a suitably ventilated battery assembly. It can be used as part of battery pack constructions where cells are interconnected using suitable nickel strips and an appropriate welding process. This product provides mechanical support only and does not include electrical connections, a Battery Management System (BMS) or battery protection circuitry.
