PVC Heat Shrink Tubing for RC Battery Packs — Reliable Wrap from 7mm to 625mm Flat Width
RC hobbyists and battery builders know the frustration of a worn, torn, or missing battery wrap — exposed cells are a safety hazard, and a sloppy pack looks unprofessional in any build. Whether you are rebuilding a LiPo pack for your race car, refreshing NiMH cells in a crawler, or protecting NiCd packs in a vintage RC boat, having the right-sized heat shrink tubing on hand makes the job clean, safe, and fast.
Each order includes PVC heat shrink tubing in your chosen flat width (7mm to 625mm), color (Red, Yellow, Blue, or Grey), and length (1M ≈ 39" or 5M ≈ 197"). The tubing is made from flexible PVC with a typical 2:1 shrink ratio, providing a firm, insulating wrap once heat is applied. With flat widths spanning 7mm (≈0.28") all the way to 625mm (≈24.6"), this listing covers everything from small single-cell cylindrical packs to large multi-cell rectangular LiPo bricks.
Typical use cases include RC battery pack rewrapping and repair, DIY battery pack assembly for RC cars, trucks, boats, and drones, and workshop organization where color-coded wraps help identify cell chemistry or voltage at a glance — making this a go-to heat shrink wrap for RC battery packs of virtually any size.
🔋 Compatible with: LiPo · NiMH · NiCd battery packs — RC cars, trucks, boats, drones, aircraft, and DIY battery builds. Flat widths 7mm–625mm cover most standard pack sizes.
✅ Key Features of These RC Battery Pack Heat Shrink Tubes
-
📏 Wide Size Range — Flat widths from 7mm (≈0.28") to 625mm (≈24.6") cover single cylindrical cells up to large multi-cell LiPo bricks, so you can find the right fit without guesswork.
-
🎨 4-Color System — Red, Yellow, Blue, and Grey options let you color-code packs by chemistry, voltage, or owner — a practical system for any RC workshop or battery builder.
-
🔥 2:1 Shrink Ratio — Shrinks to approximately half its original diameter with a heat gun, conforming tightly to the pack surface for a secure, rattle-free wrap on LiPo, NiMH, and NiCd packs.
-
🛡️ Electrical Insulation — PVC material provides a protective insulating layer that guards against shorts, abrasion, and minor moisture exposure during normal RC operation.
-
✂️ Cut-to-Length Flexibility — Available in 1M and 5M rolls, so you can cut exactly what you need for each pack rebuild or battery assembly project without waste.
-
⚡ Easy Application — Slides over the pack before shrinking, requires no adhesive, and leaves a clean finish — ideal for both first-time builders and experienced RC battery technicians.

⚠️ Size tip: To find your flat width, measure your battery pack's circumference and divide by 2. When in doubt, size up — tubing that is slightly oversized slides on easily and still shrinks to a snug fit.
❓ Frequently Asked Questions
How do I choose the right flat width for my RC battery pack?
Measure the circumference of your battery pack and divide by 2 — that gives you the required flat width. For example, a pack with a 60mm circumference needs a 30mm flat-width tube. When in doubt, size up slightly so the tubing slides on easily before shrinking. Our range covers 7mm (≈0.28") to 625mm (≈24.6"), so most standard RC battery pack sizes are accommodated.
What is the shrink ratio, and how tight will the wrap be?
This PVC heat shrink tubing typically has a 2:1 shrink ratio, meaning it shrinks to approximately half its original flat width when heat is applied evenly. The result is a firm, conforming wrap that holds the cells together and resists vibration — important for RC applications where packs experience constant movement and impact.
Is this tubing compatible with LiPo, NiMH, and NiCd batteries?
Yes. This tubing is designed for use with LiPo, NiMH, and NiCd battery packs commonly found in RC cars, trucks, boats, drones, and aircraft. It works with both rectangular multi-cell packs and cylindrical cell configurations. Always ensure the flat width you select is appropriate for your specific pack dimensions.
Can I use this heat shrink wrap outdoors or in wet conditions?
PVC heat shrink tubing provides a moisture-resistant barrier suitable for general outdoor RC use. It is not rated for full waterproof submersion. For marine RC applications or high-humidity environments, ensure the tubing is fully and evenly shrunk with no gaps at the ends, and consider additional sealing if the pack will be exposed to standing water.
What tool do I need to apply the heat shrink tubing?
A heat gun is the recommended tool for even, controlled shrinking. Hold the gun 2–4 inches from the tubing and move it steadily along the length of the pack to avoid hot spots. A lighter can work for small sections in a pinch, but a heat gun gives the most consistent results and reduces the risk of scorching the tubing or damaging the cells underneath.
Does the color I choose affect insulation or electrical performance?
No — all four colors (Red, Yellow, Blue, Grey) are made from the same PVC material and share the same insulation and shrink properties. Color selection is purely for identification and organization. Many RC builders use color coding to distinguish battery chemistries, voltage levels, or pack ownership in a shared workshop.
Should I order the 1M or 5M roll?
If you are wrapping a single battery pack or doing a one-off repair, 1M (≈39") is generally sufficient for most RC pack sizes. If you build or rebuild multiple packs, or work with larger packs that require more material per wrap, the 5M (≈197") roll offers better value and ensures you have stock on hand for future projects.
