PVC Heat Shrink Tubing for RC Battery Packs — Secure, Clean, Color-Coded Wrapping
Rebuilding a battery pack or rewrapping a worn LiPo, NiMH, or NiCd cell group is one of those jobs where the wrong wrap makes everything look sloppy — and the right one makes it look factory-fresh. Whether you're a hobbyist building custom RC packs, a technician refurbishing power tool batteries, or a maker bundling wiring harnesses, finding a PVC heat shrink tubing that fits your exact pack diameter without guesswork is the first challenge.
This PVC heat shrink tubing is available in flat widths from 15mm (≈0.59") to 200mm (≈7.87"), with inner diameters (φ) ranging from approximately 9mm to 127mm before shrinking. Each listing is sold by the meter — choose 1m, 2m, 3m, or 5m depending on how many packs you're wrapping. Colors available: Black, Blue, Transparent, White, Green, Yellow, and Red — making color-coding by cell chemistry or voltage easy.
Typical use cases include RC battery pack rewrapping for LiPo, NiMH, and NiCd packs, custom lithium-ion cell group insulation, wire harness bundling and cable management, and connector or solder joint protection in low-voltage electronics projects.
🔋
Compatibility: Fits LiPo, NiMH, NiCd, Li-ion, and other cylindrical or prismatic battery pack formats. Match the flat width to half your pack's circumference for a snug fit. Inner diameter (φ) values listed are pre-shrink expanded diameters.
⚠️
Size Tip: If your pack diameter falls between two listed sizes, choose the next size up. PVC tubing shrinks to conform — slightly oversized is easier to work with than undersized.
✅ Key Features of These PVC Heat Shrink Tubing Wraps
-
📐Wide Size Range — Flat widths from 15mm (≈0.59") to 200mm (≈7.87") cover everything from small NiCd sub-C cells to large LiPo packs used in RC cars, boats, and drones.
-
🎨7 Color Options — Black, Blue, Transparent, White, Green, Yellow, and Red allow easy color-coding by chemistry, voltage, or project — a practical advantage for multi-pack workshops.
-
🔥PVC Material with ~2:1 Shrink Ratio — Polyvinyl Chloride construction provides reliable electrical insulation and conforms tightly to irregular pack shapes when heat is applied with a standard heat gun.
-
📏Flexible Length Options — Available in 1m, 2m, 3m, and 5m cuts so you buy only what you need — no waste on single-pack jobs, enough for batch rebuilds on longer rolls.
-
⚡Electrical Insulation for Low-Voltage Use — Suitable for insulating battery terminals, wire bundles, solder joints, and connector sleeves in RC, DIY electronics, and light industrial applications.
-
✂️Easy to Cut and Apply — Cuts cleanly with scissors or a utility knife; slides over pack before shrinking with no adhesive mess. Transparent option lets you inspect cell labels underneath after wrapping.

❓ 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 60mm circumference needs approximately 30mm flat width. The inner diameter (φ) listed in each variant is the approximate expanded diameter before shrinking. When in doubt, size up slightly — the tubing will conform tightly once heat is applied.
What is the shrink ratio of this PVC tubing?
PVC heat shrink tubing typically has a shrink ratio of approximately 2:1, meaning it shrinks to roughly half its expanded diameter when heat is applied. Actual shrink ratio may vary slightly by size — contact us to confirm for a specific variant.
What temperature is needed to shrink this tubing?
PVC heat shrink tubing generally activates at temperatures between 70°C–120°C (158°F–248°F). A heat gun set to low or medium is recommended. Avoid open flames, which can cause uneven shrinking or damage the tubing.
Is this tubing suitable for outdoor or waterproof applications?
This PVC tubing provides basic moisture resistance and is suitable for general indoor and light outdoor use. It is not a dual-wall adhesive-lined tubing, so it does not provide a fully waterproof seal. For submersible or high-humidity environments, an adhesive-lined heat shrink is generally recommended.
Which battery chemistries is this compatible with — LiPo, NiMH, NiCd?
Yes, this tubing is compatible with LiPo, NiMH, NiCd, and other common RC battery pack formats. It is also widely used on Li-ion cell groups, power tool packs, and custom battery assemblies. Always ensure the flat width matches your pack's circumference before ordering.
Can I use this for electrical insulation beyond battery packs?
Yes. PVC heat shrink tubing is commonly used for wire bundling, cable labeling, connector insulation, and protecting solder joints. It provides electrical insulation suitable for low-voltage applications. For high-voltage or high-temperature environments, verify the voltage and temperature ratings with us before use.
How do I convert the flat width to inches?
Divide the flat width in mm by 25.4 to get inches. For example: 15mm ÷ 25.4 ≈ 0.59" (≈ 19/32"), 50mm ÷ 25.4 ≈ 1.97", 100mm ÷ 25.4 ≈ 3.94", 200mm ÷ 25.4 ≈ 7.87".
