Loose wraps shift during assembly; tubing that's too tight won't slide over the cell at all. This 60mm PVC heat shrink tubing is sized specifically for 18650 battery sleeving, giving DIY builders, e-bike enthusiasts, and electronics hobbyists a straightforward solution that goes on easily and shrinks down snugly.\u003c\/p\u003e\n\u003cp\u003eEach roll is made from PVC (polyvinyl chloride) and has a flat width of 60mm with an expanded diameter of approximately 38mm (≈1.5\"). After applying heat, the tubing typically shrinks to around 19mm (≈0.75\") at a roughly 2:1 ratio, conforming closely to the cell or pack surface. Available in eight colors — White, Red, Green, Blue, Clear, Yellow, Silver Gray, and Black — and five cut lengths: 1M (≈3.3 ft), 2M (≈6.6 ft), 3M (≈9.8 ft), 5M (≈16.4 ft), and 10M (≈32.8 ft).\u003c\/p\u003e\n\u003cp\u003eTypical use cases include rewrapping individual 18650 cells for vape mods and flashlights, sleeving custom lithium battery packs for e-bikes and RC vehicles, color-coding cells in multi-cell configurations for easy identification, and providing a finished insulating layer on DIY spot-welded nickel strip packs.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"hdiy-compat\"\u003e\n\u003cspan class=\"hdiy-compat-icon\"\u003e🔋\u003c\/span\u003e \u003cstrong\u003eCompatibility:\u003c\/strong\u003e Designed for 18650 lithium-ion cells and small parallel packs with an outer diameter up to approximately 38mm (≈1.5\").

It is designed to fit single 18650 cells and small parallel packs. For larger multi-cell packs, measure your pack's outer diameter before ordering and confirm it falls below 38mm. A standard 18650 cell is typically 18mm (≈0.71\") in diameter, so this tubing fits comfortably over one or two cells side by side.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eWhat is the shrink ratio and final diameter after shrinking?\u003c\/summary\u003e\n\u003cdiv class=\"hdiy-faq-body\"\u003e\n\u003cp\u003ePVC heat shrink tubing of this type typically has a 2:1 shrink ratio. Starting from an expanded diameter of approximately 38mm (≈1.5\"), the tubing will generally shrink down to around 19mm (≈0.75\") when heat is applied evenly. Actual recovered diameter may vary slightly depending on your heat source, distance, and application speed. Always do a short test piece before sleeving your full pack.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eWhat temperature is needed to shrink this tubing?\u003c\/summary\u003e\n\u003cdiv class=\"hdiy-faq-body\"\u003e\n\u003cp\u003ePVC heat shrink tubing of this type generally begins to shrink at around 70–90°C (158–194°F). A standard heat gun on a low or medium setting works well. Move the heat gun steadily along the tubing to avoid hot spots. Avoid using open flames — they can scorch or melt the PVC unevenly and may damage the cell wrapper underneath.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eIs this tubing safe for use on lithium-ion 18650 batteries?\u003c\/summary\u003e\n\u003cdiv class=\"hdiy-faq-body\"\u003e\n\u003cp\u003eYes. PVC heat shrink tubing is widely used for 18650 lithium-ion battery rewrapping and pack sleeving in DIY applications. It provides electrical insulation and mechanical protection for the cell casing. Keep finished packs away from sustained heat sources above the shrink temperature, as prolonged exposure could cause the sleeve to deform. For high-drain or high-temperature applications, verify the tubing's voltage and temperature ratings with us before use.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eCan I use this tubing outdoors or in damp environments?\u003c\/summary\u003e\n\u003cdiv class=\"hdiy-faq-body\"\u003e\n\u003cp\u003ePVC heat shrink tubing generally offers basic moisture resistance once fully shrunk, making it suitable for light indoor use and sheltered outdoor applications. It is not a waterproof seal — moisture can still enter from the open ends. For fully waterproof battery pack sleeving or prolonged outdoor exposure, an adhesive-lined polyolefin heat shrink tubing is typically a more appropriate choice.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eHow do I choose the right length for my project?\u003c\/summary\u003e\n\u003cdiv class=\"hdiy-faq-body\"\u003e\n\u003cp\u003eMeasure the total length of the section you need to cover, then add at least 10–15% extra for overlap and trimming. A standard 18650 cell is approximately 65mm (≈2.6\") long. For a 2S series pack (two cells end-to-end), you would need roughly 140mm (≈5.5\") of tubing per sleeve. The 1M roll suits single-cell rewraps and small repairs; the 5M and 10M rolls are better suited for workshop use or building multiple packs.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eDoes the color affect performance or insulation properties?\u003c\/summary\u003e\n\u003cdiv class=\"hdiy-faq-body\"\u003e\n\u003cp\u003eNo. All eight color options — White, Red, Green, Blue, Clear, Yellow, Silver Gray, and Black — are made from the same PVC material and share the same insulation and shrink characteristics.

The tubing cuts cleanly with a pair of scissors or a sharp utility knife. Because it has no adhesive lining, it can be repositioned freely before heat is applied. Cut your piece slightly longer than needed, slide it into position, then apply heat from the center outward to avoid trapping air bubbles under the
