18650 Cylindrical Battery Enclosure Set with Explosion-Proof Cap & Upper/Lower Insulation Sheets

All-in-One Components for Hassle-Free Assembly

• 18650 Cylindrical Steel Shell: Crafted from high-quality steel with exceptional structural integrity, ensuring robust protection for battery cells against external impacts and wear.
• Explosion-Proof Cap: Equipped with a built-in safety mechanism to relieve internal pressure, effectively preventing risks of overheating or explosion—critical for long-term battery reliability.
• Upper & Lower Insulation Sheets: Made of premium insulating materials, these sheets isolate the cell from the case and other components, eliminating short-circuit risks and enhancing overall electrical stability.

Core Advantages That Stand Out

• Uncompromised Safety: The combination of a durable steel shell and explosion-proof cap creates a double layer of protection, meeting global safety standards for lithium-ion battery applications.
• Precision Engineering: Each component is manufactured with strict dimensional control—perfectly fitting 18650 cells (18mm diameter × 65mm height) and compatible with automated assembly lines, boosting production efficiency.
• Easy to Integrate: The lightweight yet sturdy design, paired with pre-fitted insulation sheets, simplifies the assembly process, reducing labor time and minimizing assembly errors.
• Versatile Applications: Ideal for power tools, portable electronics, energy storage systems, electric bikes, and more—any scenario requiring reliable 18650 battery packaging.
