PVC Heat Shrink Tubing for RC Battery Packs — Secure, Clean Wraps from 280mm to 625mm
If you've ever peeled back a cracked or peeling wrap on a LiPo or NiMH pack mid-session, you know how quickly a damaged battery sleeve can become a safety concern — or at minimum, a frustrating mess. RC hobbyists, battery rebuilders, and DIY electronics enthusiasts need a reliable, heat-activated sleeve that conforms tightly to large-format battery packs without bubbling, splitting, or leaving gaps at the ends.
This PVC heat shrink tubing is available in flat widths from 280mm (≈11.0") to 625mm (≈24.6"), with corresponding post-shrink circle diameters from 178mm (≈7.0") to 398mm (≈15.7"). Each roll is sold in lengths of 1m (≈3.3 ft), 5m (≈16.4 ft), or 10m (≈32.8 ft). Colors include Black, Blue, Clear, Chartreuse, Silver Grey, and Green (available in select sizes). The tubing is made from PVC with a typically 2:1 shrink ratio.
Typical use cases include rewrapping LiPo battery packs for RC cars, trucks, and aircraft; restoring NiMH or NiCd sub-C cell packs used in power tools and RC vehicles; bundling and protecting large wire harnesses in automotive and marine wiring projects; and cosmetic refurbishment of worn battery housings where a clean, professional finish is needed.
🔋
Compatibility: Designed for LiPo, NiMH, and NiCd battery pack formats. Flat widths 280mm–625mm cover most standard RC and power tool battery pack diameters. Confirm your pack's circumference before ordering — see the FAQ below for sizing guidance.
✅ Key Features of These Large-Diameter PVC Heat Shrink Tubes
-
📐Wide Size Range — Flat widths from 280mm to 625mm cover a broad spectrum of RC battery pack diameters, from compact 2S packs to large multi-cell configurations used in 1/5-scale vehicles and aircraft.
-
🎨Multiple Color Options — Available in Black, Blue, Clear, Chartreuse, Silver Grey, and Green (select sizes), making it easy to color-code packs by chemistry, charge level, or vehicle assignment.
-
🔥Clean Heat-Activated Shrink — Activates at typically 90–120°C with a standard heat gun; conforms snugly around irregular pack shapes without adhesive residue or uneven bunching.
-
💧Moisture-Resistant PVC Construction — PVC material provides a protective barrier against incidental moisture, dust, and abrasion during normal RC operation and storage.
-
✂️Cut-to-Length Flexibility — Sold in 1m, 5m, and 10m rolls so you can cut exactly what you need for each pack; longer rolls reduce per-meter cost for battery rebuilders working in volume.
-
🔄Dual-Reference Sizing Labels — Each variant lists both flat width and post-shrink circle diameter, so you can match the tubing to your pack's actual measured diameter without guesswork.
⚠️
Sizing Note: Measure your battery pack's outer circumference and divide by π (≈3.14) to get its diameter, then select the variant whose circle diameter is slightly larger than your pack. If you're unsure, contact us to confirm before ordering.

❓ 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 178mm circle diameter needs a 280mm flat-width tube. Generally, choose a size where the tubing's circle diameter is 5–15% larger than your pack's actual diameter to ensure a snug shrink fit. When in doubt, size up — you can always trim excess length, but you can't stretch tubing that's too small.
What is the shrink ratio of this PVC heat shrink tubing?
PVC heat shrink tubing typically has a 2:1 shrink ratio, meaning it shrinks to approximately half its original diameter when heat is applied. The listed circle diameter values on each variant represent the approximate post-shrink inner diameter for reference when matching to your pack.
Can this tubing be used outdoors or in wet environments?
PVC heat shrink tubing generally provides good moisture resistance and is suitable for short-term outdoor use and incidental splash exposure. It is not rated for continuous submersion or prolonged outdoor UV exposure. For fully waterproof applications, an adhesive-lined polyolefin tubing is generally recommended instead.
Is this tubing compatible with LiPo, NiMH, and NiCd battery chemistries?
Yes. This PVC heat shrink tubing is chemically compatible with LiPo, NiMH, and NiCd battery packs. It does not react with the outer casing materials typically used on these battery types. It is widely used in the RC hobby community for rewrapping all three chemistries.
What temperature is needed to shrink this tubing, and can I use a hair dryer?
PVC heat shrink tubing typically activates at around 90–120°C (194–248°F). A heat gun set to low or medium is the recommended tool — it provides consistent, directional heat. A hair dryer generally does not reach sufficient temperatures to fully activate the shrink. Avoid open flames, as they can scorch or melt the material unevenly and may damage the battery cells underneath.
How much length should I cut for a single battery pack wrap?
Cut the tubing approximately 10–20mm (≈0.4–0.8") longer than your battery pack on each end to allow for overlap after shrinking. For example, for a 100mm long pack, cut roughly 120–140mm of tubing. This overlap folds inward cleanly when heat is applied from the center outward.
Which color should I choose for my RC battery pack?
Color choice is primarily aesthetic and organizational. Black and Blue are the most common for RC packs and provide a clean, finished look. Clear allows you to see cell labels and balance lead routing underneath the wrap. Chartreuse and Silver Grey are useful for quick visual identification when running multiple packs with different charge states or capacities. Green is available in select sizes.
Can I use this tubing for applications other than RC battery packs?
Yes. This large-diameter PVC heat shrink tubing is also commonly used for wrapping power tool battery packs, protective sleeving on large wire harnesses in automotive and marine applications, cable bundling for organization, and cosmetic restoration of worn or damaged battery housings where a clean, professional finish is needed.
