SPIDER Automation | 4-Cell 18650 Spot Welding Battery Fixture – Ceramic, 66 × 51 × 15mm | Magnetic Cell Positioning for Battery Pack Assembly
Product Overview & Fixture Design
SPIDER Automation 4-Cell 18650 Spot Welding Battery Fixture is designed to assist with positioning four 18650 cylindrical battery cells during battery pack fabrication and spot welding operations. Its single-row arrangement provides a defined placement layout, helping maintain an organised cell arrangement while preparing battery assemblies.
The fixture is manufactured from ceramic material and incorporates a magnetic holding arrangement. According to the supplied specifications, each cell position has two magnets, providing magnetic attraction to help keep the cells in place during assembly. This arrangement supports more controlled positioning while preparing cell connections and battery pack layouts.
The four-cell fixture can be used when preparing battery packs with suitable series or parallel cell configurations. The fixture provides mechanical positioning support; the actual electrical configuration depends on the required pack voltage, capacity, cell arrangement and interconnection design.
With compact dimensions of 66 × 51 × 15mm and a specified weight of 62g, this accessory is suitable for battery assembly workbenches, spot welding setups and electronics workshops. It is supplied as one fixture, without battery cells or welding equipment.
