50mm PVC Heat Shrink Tubing — Reliable Battery Pack Wrap for RC Hobbyists and DIY Builders

If you've ever dealt with a battery pack that's coming apart at the seams — loose cells, frayed wrapping, or exposed terminals — you know how quickly a small problem can sideline a project. This 50mm PVC heat shrink tubing is designed for RC hobbyists, battery rebuilders, and workshop technicians who need a clean, consistent wrap that holds up through repeated use.

Each roll is made from flexible PVC with a flat width of 50mm (φ31.84mm expanded inner diameter). Available in lengths from 1M (≈3.3 ft) to 100M (≈328 ft) and in 9 colors — Black, Blue, Transparent, Red, Fruit Green, Yellow, Silver Gray, White, and Purple — so you can match your build or color-code your packs. Cut to any length before or after shrinking.

Typical use cases include wrapping NiMH and NiCd RC battery packs, rebuilding power tool battery packs, bundling cylindrical lithium-ion cell assemblies, and organizing cable harnesses in automotive or marine DIY projects where a clean, color-coded finish matters.

ℹ️ Compatibility Note: Flat width 50mm / Expanded inner diameter φ31.84mm. Fits battery packs and cylindrical assemblies typically 25–31mm in diameter before shrinking. Confirm your pack diameter before ordering.
⚠️ Sizing Tip: If you are unsure whether this diameter fits your application, measure your battery pack's outer diameter and compare to the expanded inner diameter of φ31.84mm. Contact us to confirm before purchasing large quantities.

✅ Key Features of These 50mm PVC Heat Shrink Tubing Rolls

  • 🔋Battery Pack Ready — Sized specifically for NiMH, NiCd, and cylindrical lithium-ion RC battery pack wrapping, with an expanded inner diameter of φ31.84mm that fits most standard cell configurations.
  • ✂️Cut-to-Length Flexibility — Supplied on continuous rolls from 1M to 100M, so you cut exactly what you need for each job — no waste, no guessing.
  • 🎨9 Color Options — Black, Blue, Transparent, Red, Fruit Green, Yellow, Silver Gray, White, and Purple let you color-code battery packs by capacity, cell count, or project — a practical system for any busy workshop.
  • 🌡️Low Activation Temperature — PVC material shrinks reliably at generally 70°C–120°C (158°F–248°F), compatible with standard heat guns without risk of scorching at moderate settings.
  • 💧Basic Moisture Resistance — The PVC construction provides a protective barrier against light moisture, dust, and abrasion — suitable for indoor workshop use and light outdoor RC applications.
  • 📦Bulk Roll Savings — Longer rolls (10M, 20M, 50M, 100M) are ideal for production battery rebuilds, repair shops, or hobbyists who go through tubing regularly and want a lower cost per meter on heat shrink wrap for battery packs.

❓ 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 cover, then add at least 10–15% extra to account for shrinkage along the length axis. For a single RC battery cell that is typically 65–70mm long, 1M is generally more than enough for multiple wraps. For bulk workshop use or production runs, the 10M–100M options offer better value per meter.

What diameter does this tubing shrink down to?

The flat width of this tubing is 50mm, which corresponds to an expanded inner diameter of approximately φ31.84mm before heat is applied. After shrinking, the recovered diameter will typically be around 15–16mm depending on the material thickness and heat applied. Always verify fit with your specific battery or component before committing to a large quantity.

What temperature is needed to shrink this tubing?

PVC heat shrink tubing generally activates at temperatures between 70°C and 120°C (158°F–248°F). A heat gun set to a low or medium setting works well. Avoid open flames, as they can scorch or melt the PVC unevenly. Keep the heat source moving to ensure even shrinkage.

Is this tubing suitable for outdoor or waterproofing use?

PVC heat shrink tubing provides basic moisture resistance and is suitable for light indoor and outdoor use. However, it is not a waterproofing solution on its own — it does not have an adhesive inner lining. For applications requiring a watertight seal, consider dual-wall adhesive-lined heat shrink tubing instead.

What battery types is this compatible with?

This 50mm flat-width tubing is commonly used to wrap RC battery packs including NiMH and NiCd cell configurations. It is also suitable for wrapping lithium-ion cylindrical cell packs, tool battery rebuilds, and similar applications where the assembled pack diameter is generally in the range of 25–31mm before shrinking.

Can I cut this tubing to custom lengths?

Yes. The tubing is supplied in continuous rolls and can be cut to any length with scissors or a utility knife before or after shrinking. This makes it easy to customize coverage for different battery pack sizes or component shapes.

Does the color affect performance?

No — all color variants share the same PVC material and shrink characteristics. Color choice is purely for identification, organization, or aesthetics. Many hobbyists and technicians use different colors to distinguish battery packs by cell count, capacity, or charge cycle.
