Blue PVC Heat Shrink Tubing for RC Battery Packs — Clean Wraps from 7mm to 95mm
If you've ever dealt with a cracked, peeling, or missing battery wrap on your RC car, drone, or boat pack, you know how quickly exposed cells can become a safety hazard — and how hard it is to find the right diameter without buying a bulk assortment you'll never use. This blue PVC heat shrink tubing for RC battery packs is stocked in 25 precise sizes, so you can order exactly what fits your build without guessing.
Each listing covers a single size and length: smaller diameters (7mm–31mm flat width, Φ4mm–Φ20mm recovered) come in 2-meter (≈6.6 ft) lengths, while larger diameters (36mm–95mm flat width, Φ22mm–Φ60mm recovered) come in 1-meter (≈3.3 ft) lengths. The material is standard PVC with a 2:1 shrink ratio, compatible with LiPO, NiMH, and NiCd cell formats. Sizes span from 7mm (≈0.28") flat width up to 95mm (≈3.74") flat width to cover everything from thin stick packs to large saddle packs.
Typical use cases include rewrapping worn RC car battery packs, sleeving custom LiPO battery builds for FPV drones, and protecting NiMH sub-C cell assemblies used in competitive RC racing. The blue color also makes it easy to color-code battery packs by chemistry or charge state in a multi-pack workshop setup.
🔋
Compatible with: LiPO · NiMH · NiCd battery packs — RC cars, trucks, boats, aircraft, and FPV drones. Fits standard sub-C, A, AA, and custom prismatic cell configurations. Select your flat width based on your pack's circumference ÷ π.
✅ Key Features of These Blue PVC Heat Shrink Tubing Sleeves
-
📐
25 Sizes in One Listing Family — Flat widths from 7mm (≈0.28") to 95mm (≈3.74") cover virtually every RC battery pack format, from thin stick packs to wide saddle packs, without buying a mixed assortment.
-
🔥
2:1 Shrink Ratio — Shrinks to approximately half its flat width when heated to around 90–100°C (194–212°F), forming a tight, uniform sleeve that conforms to the contours of your battery pack.
-
🛡️
Moisture-Resistant PVC Material — Provides a protective barrier against humidity, light splashing, and workshop dust — keeping cell casings clean and reducing the risk of short circuits from surface contamination.
-
🎨
Consistent Blue Color for Easy Identification — Uniform blue pigment throughout the tubing wall lets you color-code battery packs by chemistry, voltage, or charge cycle count in a multi-pack RC workshop.
-
✂️
Cut-to-Length Flexibility — Supplied in 1M or 2M continuous lengths so you can cut each sleeve to the exact length of your battery pack, minimizing waste and maximizing the number of wraps per order.
-
⚡
Compatible with LiPO, NiMH & NiCd Chemistries — PVC is chemically inert against the cell casing materials used in all three common RC battery chemistries, making this a single-stock solution for mixed-fleet RC hobbyists.

❓ Frequently Asked Questions
How do I choose the right diameter for my RC battery pack?
Measure the circumference of your battery pack and divide by π (3.14) to get the flat diameter. Choose a tubing size whose flat width is slightly larger than that number. For example, a pack measuring roughly 50mm in circumference would typically fit a 17mm (Φ10.8mm) tube. When in doubt, size up — PVC heat shrink generally shrinks to about 50% of its flat width, so a slightly oversized tube will still conform tightly.
What shrink ratio does this PVC tubing have, and how much will it shrink?
This tubing has a standard 2:1 shrink ratio, meaning it shrinks to approximately half its original flat width when heat is applied. For example, the 20mm flat-width size recovers to approximately Φ12.7mm. The recovered diameters are listed in each variant title so you can verify the fit before ordering.
Is this tubing safe for LiPO, NiMH, and NiCd battery chemistries?
Yes. PVC heat shrink is chemically compatible with LiPO, NiMH, and NiCd battery packs. It does not react with the cell casing materials used in these chemistries and is widely used in RC hobby battery rebuilding and rewrapping. It is not intended for high-voltage industrial applications.
What temperature do I need to shrink this tubing, and can I use a heat gun?
PVC heat shrink tubing typically activates at around 90–100°C (194–212°F). A standard heat gun on a low or medium setting works well — keep it moving in slow passes to ensure even shrinkage. Avoid open flames, as they can scorch or melt the material unevenly and may damage the battery cells underneath.
Can I use this tubing outdoors or in wet/humid conditions?
PVC heat shrink provides a moisture-resistant barrier suitable for general RC use, including outdoor environments and light splashing. However, it is not rated for continuous submersion. For waterproof RC boat or amphibious vehicle applications, adhesive-lined (dual-wall) heat shrink tubing is generally a better choice.
Why do the larger sizes come in 1M lengths instead of 2M?
Larger diameter tubing (36mm flat width and above) is sold in 1-meter (≈3.3 ft) lengths because a single meter is typically sufficient to wrap one or more large battery packs. Smaller diameters (7mm–31mm) come in 2-meter (≈6.6 ft) lengths to give you more coverage for smaller cells and multi-cell stick pack configurations.
How many battery packs can I wrap with one order?
This depends on the length of your battery pack. A standard RC stick pack is generally 130–150mm (≈5–6") long. With a 2M length of smaller tubing, you can typically wrap 12–15 small packs. With a 1M length of larger diameter tubing, you can generally wrap 5–7 larger packs. Always measure your pack and add a small overlap allowance (typically 5–10mm per end) before cutting.
