Red PVC Heat Shrink Tubing for RC Battery Packs — Wrap, Protect & Identify Your Cells

If you've ever had a battery pack with torn, peeling, or missing wrap, you know how quickly exposed cells can become a safety hazard — and how hard it is to tell your packs apart in a busy pit area. Whether you're a weekend basher, a competitive racer, or a scale builder who rebuilds NiMH and NiCd packs at home, keeping your battery packs properly wrapped is one of the simplest maintenance steps you can take.

This red PVC heat shrink tubing is sold by the meter and available in flat widths from 7mm (≈0.28") up to 180mm (≈7.09"), covering inner diameters from approximately Φ 4mm up to Φ 115mm. Each length option — 1m (≈3.3 ft), 2m (≈6.6 ft), 5m (≈16.4 ft), and 10m (≈32.8 ft) — lets you buy exactly what you need, whether you're wrapping a single pack or stocking up for a full season of rebuilds. The tubing is compatible with LiPo, NiMH, and NiCd battery chemistries.

Typical applications include rewrapping RC car battery packs after cell replacement, color-coding packs by charge level or chemistry for quick identification in the field, and protecting bare cell groups in custom-built RC boat and aircraft battery assemblies. The bright red color makes these packs easy to spot and helps you maintain a consistent labeling system across your fleet.

🔋 Compatible with: LiPo · NiMH · NiCd RC battery packs — flat widths 7mm to 180mm, inner diameters Φ 4mm to Φ 115mm.

⚠️ Size check: Measure your pack's circumference and divide by 2 to find the flat width you need. If you're unsure, contact us to confirm before ordering.

✅ Key Features of These Red PVC RC Battery Heat Shrink Tubes

📐Wide Size Range — Flat widths from 7mm (Φ 4mm) to 180mm (Φ 115mm) cover single-cell sticks, 2S–6S LiPo bricks, and large NiMH/NiCd saddle packs used in 1/10 and 1/8 scale RC vehicles.
🔴Bright Red Color Coding — The vivid red finish makes it easy to identify packs by chemistry, charge state, or voltage in a crowded pit bag, reducing the risk of grabbing the wrong pack mid-race.
🔥2:1 Shrink Ratio — PVC heat shrink tubing shrinks to approximately half its flat width when heated to around 90–120°C (194–248°F), conforming snugly around cell groups without gaps or bubbles.
⚡Electrical Insulation — Provides a reliable insulating layer over bare cell casings and solder joints, reducing the risk of short circuits during handling, storage, and use in RC battery pack rebuilds.
✂️Cut-to-Length Flexibility — Available in 1m, 2m, 5m, and 10m lengths so you can cut exactly what you need for each pack. The 5m and 10m rolls are especially economical for hobbyists who regularly rebuild NiMH or NiCd packs.
💧Moisture-Resistant PVC Material — The PVC construction resists light moisture exposure, making it suitable for outdoor RC use in typical weather conditions and helping protect cell groups from humidity during storage.

❓ 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 a 30mm flat-width tube. PVC heat shrink typically shrinks to about half its flat width in diameter, so a 31mm flat tube (Φ 20mm) fits a pack with roughly a 20mm diameter. When in doubt, size up by one step — a slightly loose fit is easier to work with than one that's too tight.

What diameter battery packs does this tubing fit?

This listing covers inner diameters from approximately Φ 4mm (7mm flat) up to Φ 115mm (180mm flat), making it suitable for everything from small single-cell LiPo sticks to large multi-cell NiMH or NiCd packs used in RC cars, boats, and aircraft.

How much does PVC heat shrink tubing shrink?

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. Apply heat evenly with a heat gun set to around 90–120°C (194–248°F) for best results. Avoid open flames, which can cause uneven shrinkage or scorching.

Is this tubing safe for LiPo, NiMH, and NiCd battery chemistries?

Yes. PVC heat shrink is chemically compatible with all three common RC battery chemistries — LiPo, NiMH, and NiCd. It provides electrical insulation and physical protection without reacting with the cell casings or electrolyte. Always ensure the pack is fully cooled before applying heat shrink.

Can I use this tubing outdoors or in wet conditions?

PVC heat shrink tubing is generally moisture-resistant and suitable for typical RC outdoor use such as bashing, boating, or flying in light rain. However, it is not rated for continuous submersion. For waterproof RC builds, consider adding a secondary sealant or using adhesive-lined heat shrink over critical connections.

How much length do I need for my battery pack?

Measure the length of your battery pack and add at least 10–15mm (about 1/2") on each end for overlap and a clean finish. For a standard 2S LiPo that is typically around 100–140mm long, a 1m length gives you multiple wraps or enough for several packs. The 5m and 10m options are ideal for hobbyists who rebuild packs regularly.

What tools do I need to apply heat shrink tubing?

A heat gun is the recommended tool for even, controlled shrinkage. A hair dryer can work for smaller sizes but may not generate enough heat for larger diameters. Sharp scissors or a hobby knife are needed to cut the tubing to length. No adhesives or special tools are required.
