Cylindrical Battery Cell Bracket Modular 18650 26650 Holder 2S 3S Pack Material

Product Overview

This high-performance cylindrical battery bracket system provides an advanced structural foundation for high-density lithium-ion battery pack assembly. Fabricated from premium flame-retardant ABS and polycarbonate (PC) composite material rated to UL94 V-0 standards, the component delivers rigid mechanical positioning, superior electrical insulation, and critical inter-cell spacing. Designed specifically for standard 18650 and 26650 form-factor cylindrical cells, the spacer framework establishes structural integrity while preventing accidental short circuits, managing thermal separation, and streamlining high-throughput pack manufacturing workflows.

Engineered for modern energy storage demands, the system serves research and development laboratories, pilot production lines, and high-volume industrial manufacturing facilities. Primary use cases span electric vehicle (EV) traction packs, light electric mobility (e-bikes, e-scooters), industrial automated guided vehicles (AGVs), grid-scale energy storage systems (ESS), and high-drain power tool battery modules. The modular 2-Series (2S) and 3-Series (3S) architectures integrate precision interlocking edge slots that allow pack designers and assembly engineers to configure custom matrix layouts of virtually any rectangular or custom geometric profile.

By firmly anchoring cylindrical cells within tightly toleranced apertures—approximately 18.2 mm for 18650 cells and 26.2 mm for 26650 cells—the structural bracket prevents cell displacement during automated spot welding and manual resistance welding. This structural consistency minimizes mechanical stress on welded nickel strips or copper busbars under severe operational vibration, thermal expansion, and mechanical shock, ensuring long-term pack reliability in demanding industrial operating environments.

Key Features

• UL94 V-0 Flame-Retardant Material: Formulated with a specialized ABS and PC engineering polymer blend that self-extinguishes within seconds, inhibiting thermal runaway propagation and enhancing overall pack safety compliance.
• Precision Cell Retention Apertures: Features calibrated bore diameters of approximately 18.2 mm for 18650 cells and 26.2 mm for 26650 cells to deliver a snug, slip-fit tolerance that eliminates radial movement during assembly.
• Modular Interlocking Slot Architecture: Integrated female and male dovetail card slots along the peripheral borders enable seamless lateral and longitudinal expansion to construct customized pack dimensions without specialized tooling.
• Optimized Resistance Spot Welding Fixture: Firmly locks individual cylindrical cells at a uniform vertical height and consistent spacing, ensuring planar contact surfaces for automated resistance spot welding and ultrasonic wire bonding.
• Integrated Thermal Separation Channels: Maintains engineered air gaps between adjacent cylindrical cell walls to facilitate convective air cooling, lower internal pack operating temperatures, and mitigate localized thermal hot spots.
• Superior Impact and Vibration Resistance: Built with high flexural modulus and tensile strength to withstand continuous automotive-grade mechanical vibrations, drop forces, and cyclic dynamic loads without stress cracking.
• High Dielectric Insulation Strength: Excellent non-conductive electrical isolation characteristics prevent arc discharge, breakdown voltages, and localized shorts across neighboring cell casings and busbar networks.
• Reversible Dual-Sided Compatibility: Symmetrical geometric design accommodates top and bottom pack capping, simplifying inventory management and accelerating line assembly throughput.
