350mm PVC Heat Shrink Tubing — Reliable Battery Pack Wrap & Insulation Sleeve

Whether you're rebuilding an e-bike battery, assembling a custom LiPo pack, or protecting a DIY power bank, finding a heat shrink sleeve wide enough to cover large-format cells without seams or tape is a constant challenge. This 350mm flat width PVC heat shrink tubing is purpose-built for exactly that job — giving makers, EV hobbyists, and electronics technicians a clean, professional wrap in one piece.

Each order includes a continuous length of PVC heat shrink tubing with a 350mm (≈13.8") flat width, available in 1 Meter (≈39.4"), 2 Meter (≈78.7"), 3 Meter (≈118.1"), 4 Meter (≈157.5"), and 5 Meter (≈196.9") cuts. The tubing is made from flexible PVC with a typical 2:1 shrink ratio, available in Black, Blue, and Transparent finishes to suit functional and aesthetic builds alike.

Typical applications include wrapping 18650 and 21700 lithium-ion battery packs for e-bikes and power tools, insulating LiPo packs in RC vehicles and drones, and sleeving custom battery assemblies for solar storage systems — all scenarios where a large-diameter heat shrink battery wrap sleeve delivers a cleaner result than tape or adhesive alternatives.

ℹ️ Compatibility Note: This tubing has a 350mm flat width, suitable for battery packs or cylindrical objects with an outer circumference of up to approximately 700mm (≈27.6"). Measure your pack before ordering. For smaller diameters, see our other heat shrink tubing sizes.

✅ Key Features of These 350mm PVC Heat Shrink Tubing Sleeves

  • 📏350mm Flat Width — Covers large-format battery packs in a single seamless wrap, eliminating the need for overlapping tape or multiple smaller sleeves.
  • 🔥Even Heat Activation — Shrinks uniformly with a heat gun at typically 70–90°C (158–194°F), conforming tightly to irregular pack shapes without bubbling or lifting.
  • ⚡Electrical Insulation — PVC construction provides a dielectric barrier that helps prevent short circuits on exposed cell contacts and bus bars in DIY battery assemblies.
  • 🎨Three Color Options — Black for standard builds and UV resistance, Blue for color-coded identification, and Transparent for visible cell labels — ideal for custom battery pack wrap sleeve projects.
  • ✂️Cut-to-Length Flexibility — Sold in 1–5 Meter continuous rolls so you can cut exactly what you need for each pack, reducing waste on multi-cell battery insulation sleeve jobs.
  • 🛡️Moisture & Abrasion Resistance — The PVC film resists light moisture, dust, and surface abrasion, keeping battery pack exteriors protected during handling, transport, and installation.

❓ Frequently Asked Questions

How do I choose the right length of heat shrink tubing?

Measure the total length of the battery pack or object you need to wrap, then add at least 10–15% extra to account for shrinkage along the length axis. For example, a 900mm (≈35.4") battery pack would typically need a 1 Meter cut. Choose 2 Meter or longer for larger packs or when you need multiple wraps from a single piece.

What is the shrink ratio of this PVC tubing?

PVC heat shrink tubing generally has a 2:1 shrink ratio, meaning it shrinks to approximately half its original flat width when heat is applied. This 350mm flat-width tube is typically suited for battery packs or cylindrical objects with a circumference of up to roughly 700mm (≈27.6") before shrinking.

Can this tubing be used outdoors or in high-moisture environments?

PVC heat shrink tubing generally provides a moisture-resistant barrier suitable for indoor and light-duty outdoor use. For prolonged outdoor exposure or submersion, a dual-wall adhesive-lined heat shrink is typically recommended for a more robust seal.

What temperature is needed to shrink this tubing?

PVC heat shrink tubing typically activates at around 70–90°C (158–194°F). A heat gun set to low-to-medium heat works best. Avoid open flames, which can cause uneven shrinkage or scorching of the sleeve.

Is this tubing compatible with lithium-ion and LiPo battery packs?

Yes, this PVC heat shrink sleeve is commonly used to wrap lithium-ion, LiPo, NiMH, and lead-acid battery packs for insulation and protection. Always confirm the pack's outer circumference fits within the 350mm flat width before ordering.

Which color should I choose — Black, Blue, or Transparent?

Black is the most common choice for battery packs and provides the best UV resistance. Blue is often used for color-coding or aesthetic builds. Transparent allows you to see cell labels, barcodes, or branding underneath the wrap — ideal for custom or display builds.

Can I cut this tubing to a custom length?

Yes. The tubing is sold in continuous lengths (1–5 Meter options) and can be cut with standard scissors or a utility knife before or after shrinking. Cut cleanly at a 90° angle for the neatest finish.
