PVC Heat Shrink Tubing for RC Battery Packs — Wrap, Protect and Identify at a Glance
If you have ever grabbed the wrong battery pack mid-session or dealt with a fraying wrap that left your cells exposed, you know how much a clean, tight sleeve matters. RC hobbyists, drone builders, and DIY electronics enthusiasts need a reliable way to protect and organize their LiPo, NiMH, and NiCd packs — and generic electrical tape just does not cut it for a professional finish.
This PVC heat shrink tubing is available in flat widths from 29.5mm (18.5mm inner diameter) to 50mm (32mm inner diameter), covering the most common RC battery pack sizes. Each listing is sold by the meter — choose 1 meter, 3 meters, or 5 meters depending on how many packs you are wrapping. The tubing is available in over 20 colors including Black, White, Red, Blue, Green, Yellow, Clear, and many specialty finishes, making color-coding your pack inventory straightforward.
Typical use cases include rewrapping worn or damaged RC battery pack sleeves, building custom battery packs from individual cells, color-coding packs by chemistry or capacity in a multi-pack RC setup, and protecting exposed cell groups in DIY power tool battery rebuilds.
i
Compatibility: Designed for LiPo, NiMH, and NiCd RC battery packs. Flat width (listed first) is the lay-flat measurement; inner diameter in parentheses is the expanded pre-shrink diameter. Select a size where the expanded diameter is slightly larger than your pack widest dimension.
!
Size tip: If your pack diameter falls between two sizes, size up — a slightly loose fit before shrinking will still produce a tight wrap after heat is applied. Contact us to confirm fit for non-standard pack shapes.
Key Features of These PVC Heat Shrink Tubing Sleeves
-
🔥Clean Heat-Activated Shrink — Applies evenly with a standard heat gun; the tubing conforms tightly to rectangular and cylindrical RC battery pack shapes without bubbling or lifting at the edges.
-
📏Seven Size Options — Flat widths from 29.5mm to 50mm cover the most common LiPo, NiMH, and NiCd pack dimensions used in RC cars, boats, planes, and drones.
-
🎨20+ Color Variants — From solid Black and White to Clear, Clear Gold, Tyrant Gold, Sky Blue, and Army Green — color-code your battery packs by cell count, chemistry, or capacity for instant identification in the field.
-
💧Moisture-Resistant PVC Material — The PVC construction provides a protective barrier against light moisture, dust, and abrasion, helping extend the usable life of rewrapped battery packs.
-
✂️Cut-to-Length Flexibility — Available in 1m, 3m, and 5m lengths so you can buy exactly what you need for a single pack rewrap or stock up for a full battery rebuild project.
-
⚡Electrically Insulating — PVC heat shrink tubing is generally electrically insulating, making it suitable for wrapping cell groups and protecting exposed connections in DIY battery pack builds.

Frequently Asked Questions
How do I choose the right flat width for my battery pack?
Measure the circumference of your battery pack and divide by 2 to get the required flat width. For example, a pack with a 60mm circumference needs approximately 30mm flat width tubing. The inner diameter shown in the variant name is the expanded diameter before shrinking. Generally, choose a size where the expanded diameter is 10-20% larger than your pack widest dimension for a snug, wrinkle-free finish. When in doubt, size up — you can always shrink a slightly larger tube down tightly.
What shrink ratio does this PVC tubing have?
PVC heat shrink tubing typically has a 2:1 shrink ratio, meaning it shrinks to approximately half its expanded diameter when heat is applied. The listed inner diameter represents the pre-shrink expanded size. Always verify your pack dimensions against the variant specs before ordering to ensure a proper fit after shrinking.
Is this tubing compatible with LiPo, NiMH, and NiCd battery packs?
Yes. This PVC heat shrink tubing is generally compatible with LiPo, NiMH, and NiCd RC battery packs. It is designed to conform tightly around the rectangular and cylindrical pack shapes commonly used in RC cars, boats, planes, and drones. It can also be used for DIY power tool battery rebuilds and other electronics projects.
Can I use this tubing outdoors or in wet conditions?
PVC heat shrink tubing provides a moisture-resistant barrier that is generally suitable for light outdoor use. However, it is not rated for full waterproof submersion. For extended outdoor or wet-environment use, consider additional sealing measures at the pack terminals. In most cases, standard RC outdoor use including bashing, boating on calm water, or flying is within the typical use range of this material.
What tool do I need to shrink this tubing?
A standard heat gun is recommended for even, controlled shrinking. Apply heat evenly along the length of the tubing, moving the heat source continuously to avoid scorching or uneven shrinkage. A lighter can work for small sections but risks scorching the PVC. A hair dryer on its highest setting may work but will generally take longer and may not produce as tight a finish as a dedicated heat gun.
How much length do I need for one battery pack?
For a single RC battery pack, you typically need 10-20% more length than the pack itself to allow for overlap at the ends. A 1-meter length is generally sufficient for 3-6 standard RC packs depending on pack size. The 3-meter and 5-meter options are ideal for builders who wrap multiple packs or want material on hand for future builds. If you are rebuilding a large number of packs, the 5-meter length offers the best value per meter.
Do the colors affect performance or are they purely cosmetic?
The colors are primarily cosmetic and are commonly used by RC hobbyists to color-code battery packs by cell count, chemistry, or capacity for quick identification in the field. All color variants share the same material properties and shrink characteristics. Clear variants allow you to see cell labels or markings through the tubing, which can be useful for inventory management.
