PVC Heat Shrink Tubing for RC Battery Packs — Secure, Insulate, and Identify Your Packs
If you've ever had a battery pack with a torn wrapper, loose cells, or no way to tell your 3S from your 4S at a glance, you know how quickly a disorganized battery box becomes a problem. This PVC heat shrink tubing is designed for RC hobbyists, DIY electronics builders, and repair technicians who need a reliable, clean way to wrap and protect LiPo, NiMH, and NiCd battery packs of all sizes.
Each order includes 1 meter of PVC heat shrink tubing in your chosen flat width and color. Flat widths range from 103mm (Φ65mm) to 500mm (Φ318mm), covering everything from compact 2S packs to large multi-cell configurations. Select sizes are also available in a thickened wall version for added durability. Colors include Black, White, Yellow, Green, Blue, Red, Transparent, Fruit Green, and Silver Gray — making color-coding your battery inventory straightforward.
Common use cases include rewrapping RC car, boat, and drone battery packs after cell replacement, color-coding battery sets by cell count or capacity, protecting DIY 18650 and cylindrical cell packs, and insulating custom power tool battery rebuilds. The tubing is also used in e-bike battery pack assembly and general electronics insulation projects.
🔋
Compatible with: LiPo, LiIon, NiMH, NiCd, and 18650 cylindrical cell battery packs. Suitable for RC cars, boats, drones, e-bikes, and DIY power tool battery rebuilds. Check the flat width (Φ diameter) against your pack's circumference before ordering.
✅ Key Features of These PVC Heat Shrink Battery Pack Wraps
-
📐Wide Size Range — Flat widths from 103mm (Φ65mm) to 500mm (Φ318mm) cover compact 2S packs through large multi-cell configurations, so you can find the right fit without cutting down oversized tubing.
-
🎨9 Color Options — Black, White, Yellow, Green, Blue, Red, Transparent, Fruit Green, and Silver Gray let you color-code battery packs by cell count, capacity, or owner — a practical system for any RC pit box or workshop.
-
🛡️Standard and Thickened Wall Variants — Select sizes offer a thickened wall option for battery packs that experience vibration or physical stress during use, providing a more rigid and protective finished wrap.
-
⚡Electrically Insulating PVC Material — PVC heat shrink tubing provides electrical insulation around battery cells and connections, reducing the risk of shorts from incidental contact with conductive surfaces.
-
🔥Low Activation Temperature — Shrinks at typically 70°C–90°C (158°F–194°F), compatible with standard heat guns. No open flame required, making application straightforward even for first-time battery rebuilders.
-
✂️Cut-to-Length Flexibility — Sold in 1-meter lengths that you cut to your exact pack length. Order multiple meters for batch wrapping or to keep spares on hand for future rebuilds.

⚠️
Sizing note: The flat width listed (e.g., 103mm) is the tubing measured flat before shrinking. The Φ value (e.g., Φ65mm) is the approximate inner diameter. Measure your battery pack's circumference and divide by π (≈3.14) to estimate the required inner diameter, then select the closest flat width. When in doubt, size up.
❓ 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 approximate flat width needed. For example, a pack with a 130mm circumference needs roughly a 65mm flat width — matching our 103mm (Φ65mm) option. As a general rule, choose a flat width 10–20% larger than the calculated value so the tubing slides on easily before shrinking. The Φ diameter listed in each variant name is the approximate inner diameter after the tubing is opened into a tube shape.
What is the shrink ratio, and how much will the tubing shrink?
PVC heat shrink tubing typically has a 2:1 shrink ratio, meaning it shrinks to approximately half its original flat width diameter when heat is applied evenly. For example, a 200mm flat width tubing will generally shrink to fit a pack with a circumference of around 200mm. Exact shrink behavior may vary slightly by size — contact us to confirm for your specific variant if precision fit is critical.
What temperature do I need to shrink this tubing?
PVC heat shrink tubing generally activates at 70°C–90°C (158°F–194°F). A heat gun set to a low or medium setting works well. Move the heat gun steadily along the tubing to shrink evenly from one end to the other. Avoid using open flames — they can cause uneven shrinking, scorching, or damage to the tubing and the battery pack underneath.
Can I use this tubing outdoors or in wet conditions?
PVC heat shrink tubing provides basic moisture resistance and is suitable for indoor RC use and short-term outdoor exposure in normal conditions. It is not a fully waterproof seal. For applications requiring prolonged outdoor exposure, high humidity, or submersion resistance, a dual-wall adhesive-lined heat shrink tubing would generally be a better choice.
Is this compatible with LiPo, NiMH, and NiCd battery packs?
Yes. This PVC heat shrink tubing is widely used to wrap and protect LiPo, NiMH, and NiCd RC battery packs. It is electrically insulating and conforms tightly to the pack shape after shrinking. It is also commonly used for 18650 cylindrical cell packs and DIY power tool battery rebuilds. Always ensure the tubing is fully shrunk and free of gaps before use.
What is the difference between the standard and thickened wall options?
The thickened wall variants offer greater mechanical protection and produce a more rigid finished wrap. This is useful for battery packs that experience physical stress, vibration, or impact during use — such as RC car packs mounted in a chassis. Standard wall tubing is lighter, easier to apply, and sufficient for most general battery wrapping tasks where mechanical stress is not a concern.
How much tubing do I receive per order, and can I order more than 1 meter?
Each listing is sold per 1-meter length (≈39.4"). To order multiple meters of the same size and color, simply increase the quantity at checkout. If you need a custom length or bulk quantity, contact us and we will do our best to accommodate your request.
