PVC Heat Shrink Tubing for RC Battery Packs — Rebuild, Insulate & Protect with Confidence
If you've ever dealt with a cracked, peeling, or missing battery wrap on your RC car, truck, boat, or aircraft pack, you know how quickly exposed cells can become a safety hazard. DIY builders, battery rebuilders, and RC hobbyists who want a clean, professional-looking finish need a reliable PVC heat shrink tubing that fits a wide range of pack sizes without guesswork.
Each listing covers 1 meter (≈39.4") of PVC heat shrink tubing per order. Flat widths range from 130mm (≈5.1") to 500mm (≈19.7"), with each size labeled by both flat width and inner diameter (Ø) so you can match your pack precisely — for example, 130mm flat / Ø83mm, up to 500mm flat / Ø318mm. Available in 9 colors: Black, Blue, Transparent, Light Green, Silver Gray, Red, White, Green, and Yellow.
Typical use cases include rewrapping LiPo battery packs for RC cars and trucks, rebuilding NiMH or NiCd stick packs for vintage RC models, insulating custom battery assemblies for FPV drones and RC boats, and color-coding packs by chemistry or capacity for easy identification in the field.
🔋
Compatibility: Designed for LiPo, NiMH, and NiCd RC battery packs. Works with stick-style, saddle-pack, and custom cell configurations. Select the flat width whose Ø value is slightly larger than your pack's outer diameter for a snug fit.
✅ Key Features of These PVC Heat Shrink Tubing Wraps
-
📐Wide Size Range — Flat widths from 130mm to 500mm (Ø83mm–Ø318mm) cover virtually every RC battery pack format, from compact 2S LiPo cells to large multi-cell NiMH saddle packs.
-
🎨9 Color Options — Choose from Black, Blue, Transparent, Light Green, Silver Gray, Red, White, Green, and Yellow to color-code packs by chemistry, capacity, or owner — or go transparent to keep cell labels visible.
-
🔥Low-Temperature Activation — PVC shrink tubing typically activates at around 70–90°C (160–195°F), making it easy to apply with a standard hobby heat gun without risking damage to sensitive battery cells.
-
🛡️Insulating & Abrasion-Resistant Sleeve — Once shrunk, the tubing forms a firm sleeve that insulates exposed terminals, resists abrasion from chassis contact, and helps hold cells together during high-vibration RC use.
-
💧Moisture-Resistant Finish — The PVC material provides a degree of moisture resistance suitable for light outdoor RC use, helping protect battery cells from dust, humidity, and light splash exposure.
-
✂️Easy to Cut & Apply — Each 1m length can be cut to your exact pack length. Slide over the pack before or after assembly, apply heat evenly, and achieve a clean, wrinkle-free wrap in minutes — no adhesives or special tools required beyond a heat gun.

Size Selection Tip: Measure your battery pack's circumference, divide by 2 to get the required flat width, then choose the next size up for a clean, wrinkle-free fit. If you're unsure, contact us with your pack dimensions and we'll help you select the right variant.
❓ 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 160mm circumference needs approximately 80mm flat width. Because PVC shrinks roughly 40–50% in diameter, choose a flat width that is slightly larger than half the pack circumference to ensure a snug, wrinkle-free fit. When in doubt, size up by one step. Each variant also lists the inner diameter (Ø) — compare this directly to your pack's outer diameter for a quick check.
What diameter does each flat width correspond to?
Each variant shows both the flat width and the corresponding inner diameter (Ø). For example, 130mm flat width corresponds to approximately Ø83mm, and 500mm flat width corresponds to approximately Ø318mm. Select the variant whose Ø value is closest to — but slightly larger than — your battery pack's outer diameter for the best fit.
What temperature is needed to shrink this tubing?
PVC heat shrink tubing typically activates at around 70–90°C (160–195°F). A heat gun set to low or medium is generally sufficient. Avoid open flames, as uneven heat can cause bubbling or uneven shrinkage. Keep the heat gun moving steadily around the pack for a smooth, uniform finish. Do not overheat, as excessive temperatures can damage battery cells.
Is this tubing strong enough to protect my battery pack during RC use?
Once shrunk, PVC tubing forms a firm, tight sleeve that resists abrasion and minor impacts during normal RC use. It is not designed to be a structural component, but it effectively holds cells together, insulates terminals, and protects against dust and moisture ingress in typical hobby environments. For high-impact bashing or racing applications, inspect the wrap periodically for wear.
Can I use this tubing outdoors or in wet conditions?
PVC heat shrink tubing generally provides a degree of moisture resistance once properly applied, making it suitable for light outdoor use. However, it is not rated for full waterproofing or prolonged submersion. For RC vehicles used in rain or wet terrain, ensure all seams are fully shrunk and consider additional sealing at the ends of the wrap.
Is this compatible with LiPo, NiMH, and NiCd battery packs?
Yes. This PVC heat shrink tubing is compatible with LiPo, NiMH, and NiCd battery pack formats commonly used in RC cars, trucks, boats, and aircraft. It works with both stick-style and saddle-pack configurations, provided you select the correct flat width for your pack's dimensions.
How do I decide between the available colors?
Color choice is primarily aesthetic, but it can also serve a practical purpose. Many hobbyists use different colors to distinguish battery chemistry (e.g., black for LiPo, blue for NiMH) or charge level groups. Transparent tubing lets you inspect cell labels and condition without removing the sleeve — a popular choice for builders who want to monitor their packs closely.
