PVC Heat Shrink Tubing for RC Battery Packs — Durable Protection in 30 Widths & 25 Colors
If you've ever peeled back a cracked, faded, or poorly fitted battery wrap mid-build, you know how frustrating it is to start over. RC hobbyists, battery rebuilders, and electronics DIYers need a reliable sleeve that fits precisely, shrinks cleanly, and stays put — whether you're wrapping a compact 7-cell NiMH stick pack or a wide LiPO saddle pack. This PVC heat shrink tubing is designed for exactly that job.
Each listing is sold by the meter (1 Meter per order) and is available in flat widths from 7mm (≈0.28") to 120mm (≈4.72"), covering the full range of common RC battery form factors. The tubing is made from flexible PVC with a 2:1 shrink ratio, meaning it conforms tightly to the contours of your pack once heat is applied. Choose from 25 colors — including clear, black, white, and a full spectrum of vibrant options — to color-code your packs by chemistry, voltage, or capacity.
Typical use cases include rewrapping LiPO flat packs for drone and crawler builds, resleeve NiMH and NiCd stick packs for vintage RC cars, protecting solder joints and wire bundles in custom electronics, and labeling battery packs by color for quick field identification. The wide size range also makes this tubing useful for general DIY wiring, tool handle grips, and cable management projects.
🔋
Compatible with: LiPO, LiFe, NiMH, NiCd, and Li-Ion battery packs — as well as general wire bundling, connector protection, and DIY electronics projects.
⚠️
Size tip: Measure your battery pack's flat width or circumference before ordering. If you're between sizes, size up — the tubing will conform snugly once heat is applied. Contact us to confirm fit for unusual pack shapes.

❓ Frequently Asked Questions
How do I choose the right flat width for my battery pack?
Measure the flat width or circumference of your battery pack before ordering. The tubing's flat width should be roughly 5–15% larger than the half-circumference of the pack. For example, a cylindrical cell with a 20mm diameter has a circumference of about 63mm, so a 36mm flat-width tube (which opens to ≈72mm) is typically a good fit. When in doubt, size up — you can always trim excess length, and the tubing will conform snugly once heat is applied.
What is the shrink ratio, and how much will the tubing shrink?
This PVC heat shrink tubing generally has a 2:1 shrink ratio, meaning it shrinks to approximately half its original expanded diameter when heat is applied. It also shrinks slightly in length (typically 5–10%), so add a little extra length when cutting to ensure full coverage after shrinking.
Can I use this tubing outdoors or in wet conditions?
PVC heat shrink tubing is generally moisture-resistant and provides a protective barrier against dust and light splashing, making it suitable for most outdoor RC use. However, it is not rated for full submersion. For environments with heavy moisture exposure, ensure all connections are properly sealed before applying the sleeve.
Is this compatible with LiPO, NiMH, and NiCd battery chemistries?
Yes. This PVC sleeve is chemically inert and does not react with the outer casing of LiPO, NiMH, or NiCd battery packs. It is widely used in the RC hobby community for rewrapping and protecting battery packs of all common chemistries, including LiFe and Li-Ion.
What tool do I need to shrink the tubing, and what temperature should I use?
A standard heat gun set to low or medium is recommended. PVC heat shrink tubing typically activates at around 70–90°C (158–194°F). Move the heat gun slowly and evenly along the tubing to avoid hot spots. Avoid open flames, as they can scorch or melt the tubing unevenly. A hair dryer may work for very thin-walled tubing but is generally less effective than a heat gun.
How do I cut the tubing to the correct length?
Use sharp scissors or a utility knife for a clean, straight cut. Measure the length of your battery pack and add approximately 10–20mm (about 0.5–0.75") on each end to allow for overlap after shrinking. Since PVC tubing shrinks slightly in length when heat is applied, this extra allowance ensures full coverage of the pack.
Can this tubing be used for applications other than RC batteries?
Absolutely. This tubing is commonly used for wire bundling, cable labeling, tool handle grips, and protecting connectors or solder joints. The wide range of widths — from 7mm to 120mm — makes it versatile for both small electronics and larger DIY projects around the shop or garage.
How do I convert flat width to the actual expanded diameter?
The expanded (open) diameter of the tubing is approximately twice the flat width divided by π, or more simply: expanded diameter ≈ flat width × 2 ÷ 3.14. For example, a 50mm flat-width tube has an expanded diameter of roughly 32mm (≈1.26"). In practice, the tubing is flexible and can stretch slightly beyond this, so it will generally slide over objects up to the expanded diameter.
