PVC Heat Shrink Tubing for RC Battery Packs — Reliable Insulation from 7mm to 150mm
If you've ever had a battery pack with frayed wrapping, exposed cells, or a sleeve that split mid-race, you know how quickly a small packaging failure can sideline an entire build. RC hobbyists, drone builders, and electronics repair technicians need a sleeving solution that goes on cleanly, shrinks uniformly, and stays put — whether the pack is a compact 2S LiPo or a large NiMH stick pack.
This PVC heat shrink tubing is sold in 1-meter (≈39.4") lengths and is available in flat widths from 7mm (≈0.28") to 150mm (≈5.9"), with recovered inner diameters ranging from Ø4mm (≈0.16") to Ø95mm (≈3.74"). Each variant clearly lists both the flat width and the post-shrink inner diameter (Ø) so you can match the right size to your pack without guesswork. Ten colors are available — Black, White, Blue, Red, Green, Yellow, Transparent, Fruit Green, Gray, and Purple — making it easy to color-code packs by cell count, voltage, or owner.
Typical use cases include rewrapping RC car battery packs after cell replacement, sleeving NiMH sub-C stick packs for RC aircraft, bundling parallel LiPo cells for custom drone builds, and protecting soldered wire harnesses in hobby electronics. The transparent option is especially useful when you need to keep cell labels or capacity markings visible after wrapping.
🔋
Compatible with LiPo, LiFe, NiMH, NiCd, and Li-Ion battery packs. Suitable for RC cars, RC aircraft, drones, and general hobby electronics. Verify the recovered inner diameter (Ø) matches your pack's cross-section before ordering.
✅ Key Features of These PVC Heat Shrink Tubing Sleeves
-
📐Wide Size Range — Flat widths from 7mm to 150mm cover everything from single 18650 cells to large multi-cell RC battery packs, with the recovered inner diameter (Ø) clearly listed per variant.
-
🎨10 Color Options — Black, White, Blue, Red, Green, Yellow, Transparent, Fruit Green, Gray, and Purple let you color-code packs by chemistry, voltage, or user — a practical system for any multi-pack workshop.
-
⚡Electrical Insulation — PVC material provides a non-conductive outer layer that protects battery cells from accidental shorts caused by contact with metal chassis components or other packs.
-
🔥Low Activation Temperature — Typically shrinks at around 70–90°C (158–194°F), making it compatible with standard heat guns without requiring high-temperature tooling or open flame.
-
✂️Cut-to-Length Flexibility — Each 1M piece can be trimmed to any shorter length before or after shrinking, so there's no waste when wrapping packs of varying sizes in the same session.
-
🏷️Transparent Option for Label Visibility — The clear variant lets you keep manufacturer labels, capacity ratings, and cell markings readable after sleeving — useful for warranty tracking and pack identification in multi-pack setups.

⚠️
Sizing note: The flat width listed (e.g., 27mm) is the width when the tubing lies flat — not the inner diameter. Always refer to the Ø value in the variant name to match your battery pack's cross-section. When in doubt, size up by one step.
❓ Frequently Asked Questions
How do I choose the right size heat shrink tubing for my battery pack?
Measure the widest cross-section of your battery pack or bundle. The tubing's inner diameter (Ø) should be slightly larger than that measurement before shrinking. As a general rule, PVC heat shrink tubing typically shrinks to about 50% of its original diameter. For example, a 7mm tube (Ø4mm recovered) suits small single cells, while a 150mm tube (Ø95mm recovered) fits large multi-cell packs. When in doubt, size up by one step.
What is the shrink ratio of this PVC tubing?
This PVC heat shrink tubing generally has a 2:1 shrink ratio, meaning it typically shrinks to approximately half its original diameter when heat is applied. The recovered (post-shrink) inner diameter is listed in the variant name (e.g., 7mm outer = Ø4mm recovered).
What temperature is needed to shrink this tubing?
PVC heat shrink tubing generally activates at temperatures around 70–90°C (158–194°F). A heat gun on a low setting works well. Avoid open flames, which can cause uneven shrinking or discoloration. Always apply heat evenly by moving the heat source along the length of the tubing.
Is this tubing suitable for outdoor or waterproof applications?
PVC heat shrink tubing provides basic moisture resistance and is suitable for indoor and light outdoor use. It is not a fully waterproof seal — for applications requiring IP-rated waterproofing, consider dual-wall adhesive-lined tubing instead. This product is primarily designed for battery pack insulation and bundling.
Is this tubing compatible with LiPo, NiMH, and NiCd battery chemistries?
Yes. This PVC sleeving is chemically compatible with LiPo, NiMH, and NiCd battery packs commonly used in RC cars, RC aircraft, drones, and hobby electronics. It provides electrical insulation and physical protection for the outer surface of the pack.
Can I cut this tubing to a custom length?
Yes. Each piece is sold as a 1-meter length and can be cut to any shorter length with scissors or a utility knife before or after shrinking. For longer packs, you can order multiple meters and overlap sections slightly for full coverage.
What colors are available and does color affect performance?
Available colors include Black, White, Blue, Red, Green, Yellow, Transparent, Fruit Green, Gray, and Purple. Color is purely cosmetic and does not affect electrical or thermal performance. Transparent tubing is popular when you want to display labels or cell markings underneath.
How do I measure the flat width vs. the inner diameter?
The size listed (e.g., 27mm) refers to the flat width — the width of the tubing when laid flat. The inner diameter before shrinking is approximately flat width ÷ π × 2. We also list the Ø (recovered inner diameter) in each variant name for clarity. Always refer to the Ø value when matching to your battery pack's cross-section.
