PVC Heat Shrink Tubing for RC Battery Packs — Secure, Clean, and Ready to Shrink

Anyone who has built or repaired an RC battery pack knows the frustration of cells that shift, connectors that snag, and bare packs that pick up every scratch in the field. This PVC heat shrink tubing for RC battery packs gives hobbyists, builders, and repair technicians a fast, reliable way to wrap and protect battery assemblies of almost any size — from compact 2S packs to large 6S bricks.

Each listing covers a single flat-width size, available in flat widths from 40mm (≈1.57") to 180mm (≈7.09"), with corresponding inner diameters ranging from Ø25.5mm (≈1.00") to Ø114.6mm (≈4.51"). The tubing is made from flexible PVC and is sold in three packing quantities — 1m (≈3.3 ft), 5m (≈16.4 ft), and 20m (≈65.6 ft) — so you can buy exactly what your project requires. Four color options are available: Black, White, Blue, and Transparent.

Typical use cases include rewrapping LiPo and NiMH RC battery packs after cell replacement, bundling parallel battery assemblies for drones and crawlers, and protecting DIY power tool battery rebuilds. The wide size range also makes this tubing useful for large-format applications such as e-bike battery packs and custom power supply enclosures.

🔋 Compatibility Note: Flat width determines fit. Measure your battery pack circumference and divide by 2 to find the correct flat width. See the FAQ below for a step-by-step sizing guide. If you are unsure, size up — PVC shrink tubing typically shrinks 40–50% in diameter.

✅ Key Features of These PVC Heat Shrink Tubing Wraps

  • 📐Wide Size Range — Flat widths from 40mm to 180mm cover compact RC packs through large e-bike battery assemblies, all in one product line.
  • 🎨4 Color Options — Black, White, Blue, and Transparent let you color-code packs by cell chemistry, voltage, or capacity for fast field identification.
  • 🔥Low Activation Temperature — PVC heat shrink tubing generally activates between 70°C–105°C (160°F–220°F), making it compatible with standard heat guns without risk of cell damage from excessive heat.
  • 💧Moisture-Resistant Sleeve — The PVC material provides a protective barrier against light moisture, dust, and abrasion — keeping battery cell wraps and solder joints cleaner between uses.
  • ✂️Cut-to-Length Flexibility — Sold in 1m, 5m, and 20m rolls so you can cut exactly what you need for single-pack repairs or bulk battery rebuild projects.
  • 🔄Minimal Longitudinal Shrinkage — Length shrinkage is typically less than 5%, so the tubing stays close to your cut length after shrinking — no need to over-cut to compensate.

❓ Frequently Asked Questions

How do I choose the right flat width for my battery pack?

Measure the circumference of your battery pack, then divide by 2 to get the required flat width. For example, a pack with a 100mm circumference needs a 50mm flat-width tube. When in doubt, size up slightly — PVC shrink tubing typically shrinks 40–50% in diameter, so there is some tolerance. All flat widths and their corresponding inner diameters are listed in the variant selector above.

What temperature is needed to shrink this tubing?

PVC heat shrink tubing generally activates at temperatures between 70°C and 105°C (160°F–220°F). A heat gun set to low or medium is typically sufficient. Avoid open flames, which can scorch or melt the material unevenly.

Can this tubing be used outdoors or in wet environments?

PVC heat shrink tubing generally provides good moisture resistance and is suitable for light outdoor use. However, it is not rated for continuous submersion. For fully waterproof applications, a dual-wall adhesive-lined heat shrink is generally recommended instead.

Is this tubing compatible with LiPo, NiMH, and Li-Ion battery packs?

Yes. This PVC heat shrink tubing is commonly used to wrap LiPo, NiMH, and Li-Ion RC battery packs. It provides a snug, protective sleeve that holds cells together and protects against abrasion. Always confirm the flat width matches your pack dimensions before ordering.

How much does the tubing shrink when heat is applied?

PVC heat shrink tubing in this style typically shrinks approximately 40–50% in diameter when heat is applied. Longitudinal (length) shrinkage is generally minimal — typically less than 5%. Plan your cut length accordingly.

Which color should I choose?

Color choice is primarily aesthetic. Black and blue are popular for RC builds for a clean, finished look. White works well when you want to write labels or markings on the pack. Transparent allows you to see the cells or labels underneath — useful for identification or inspection.

How do I calculate how much tubing I need?

Measure the length of your battery pack and add 10–20mm on each end for overlap. For a single pack, 1m is generally more than enough. If you are wrapping multiple packs or want material for re-wrapping, the 5m or 20m options offer better value per meter.
