Supplier's note

  1. Key Breakthroughs:

    • Adjustable Contacts: Enables field customization for mixed battery sizes (e.g., 18650 vs. 20700).
    • UL94 V-0 Material: 30% better flame resistance than standard plastics, meeting industrial safety standards.
    • Modular Design: Compatible with optional BMS integration slots (Pro Model only).

  2. Version Selection Guide:

    • Base Model: Suitable for hobbyists or low-cycle applications (e.g., LED lights).
    • Advanced Model: Ideal for robotics or drones needing 25% higher insulation for high-voltage projects.
    • Pro Model: Engineers requiring extreme durability (e.g., industrial sensors) benefit from 5,000+ insertion cycles and 10kV insulation—outperforming competitors by 40%.

With the Pro Model’s reinforced tabs, you can safely handle 20A continuous loads—twice the capacity of standard holders. Pair its 10kV insulation with high-voltage motors to eliminate arcing risks in demanding environments.
