PVC Heat Shrink Tubing for RC Battery Packs — Reliable Wrap for LiPo, NiMH & NiCd

If you've ever had a battery pack with a torn, cracked, or missing outer sleeve, you know how quickly exposed cells can become a safety concern — and how hard it is to find the right size wrap without ordering a full industrial roll. This PVC heat shrink tubing is stocked specifically for RC hobbyists, battery builders, and DIY repair technicians who need a clean, snug wrap in the exact flat width and length they actually need.

Each listing covers a single continuous piece of tubing in your chosen flat width and length. Flat widths range from 7mm (≈4mm recovered inner diameter) up to 330mm (≈210mm recovered inner diameter), with lengths available in 1M (≈3.3 ft), 2M (≈6.6 ft), and 5M (≈16.4 ft). Several sizes are also offered in a "Thick" wall variant for added durability. Color options include standard blue as well as purple-blue, sky blue, lake blue, and clear blue at select sizes.

Typical use cases include rewrapping individual LiPo cells and assembled packs for RC cars, trucks, and aircraft; resleeve NiMH and NiCd sub-C stick packs for power tools and RC vehicles; and protecting custom battery assemblies in robotics and DIY electronics projects where a clean, insulating outer layer is needed.

🔋 Compatibility: Designed for LiPo, NiMH, and NiCd battery pack rewrapping. Select your flat width based on your pack's circumference ÷ 2. See FAQ below for sizing guidance.

⚠️ Sizing note: The listed flat width is the lay-flat (pre-shrink) measurement. Recovered inner diameter is typically about 60–65% of the flat width. If your pack diameter is close to the recovered size, size up one step to ensure easy installation.

✅ Key Features of These PVC Heat Shrink Tubing Wraps

📐Wide Size Range — Flat widths from 7mm to 330mm cover everything from individual 18650 cells to large multi-cell RC battery packs, eliminating the need to buy oversized industrial rolls.
🔥Low-Temperature Activation — PVC heat shrink tubing typically activates at around 70–90°C (158–194°F), making it compatible with a standard heat gun without risking damage to sensitive battery cells.
🛡️Insulating Outer Layer — Once shrunk, the tubing forms a snug, electrically insulating sleeve that protects cell wraps from abrasion, short-circuit risk, and incidental moisture during normal RC use.
✂️Cut-to-Length Flexibility — Available in 1M, 2M, and 5M rolls so you can cut exactly what you need for each battery pack rewrap job without waste.
🎨Multiple Color Finishes — Standard blue plus purple-blue, sky blue, lake blue, and clear blue options at select sizes let you color-code packs by chemistry, voltage, or capacity for quick field identification.
🏗️Thick-Wall Variants Available — Select flat widths include a "Thick" wall option that provides greater abrasion resistance and a more rigid finished sleeve, suited for high-impact RC applications and power tool battery packs.

❓ 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 cylindrical pack with a 50mm circumference needs tubing with a flat width of about 25mm. The listed flat width is the lay-flat measurement; the recovered inner diameter is typically about 60–65% of that value. When in doubt, size up slightly — the tubing will shrink down snugly around the pack.

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 set to low or medium is typically sufficient. Move the heat gun steadily along the tubing to shrink evenly. Avoid open flames, which can scorch or melt the material unevenly and may damage the battery cells underneath.

Can this tubing be used outdoors or in wet environments?

PVC heat shrink tubing generally provides good moisture resistance for short-term or incidental exposure — such as splashes during RC use. For prolonged outdoor exposure or submersion, a dual-wall adhesive-lined heat shrink is typically recommended for a fully sealed, waterproof result. This tubing is best suited for standard RC and hobby battery rewrapping applications.

Is this tubing compatible with LiPo, NiMH, and NiCd battery chemistries?

Yes. This PVC heat shrink tubing is chemically compatible with the outer casings of LiPo, NiMH, and NiCd battery cells and packs. It does not react with the battery chemistry and is widely used for rewrapping and protecting RC battery packs across all three chemistries.

How much does the tubing shrink when heat is applied?

This PVC heat shrink tubing in this style typically has a shrink ratio of approximately 2:1, meaning it shrinks to roughly half its original flat-width diameter. The recovered inner diameter is generally about 60–65% of the listed flat width. For example, a 50mm flat-width piece typically recovers to an inner diameter of around 30–32mm (≈1.2").

Can I cut this tubing to a custom length?

Yes. The tubing is sold in 1M (≈3.3 ft), 2M (≈6.6 ft), and 5M (≈16.4 ft) lengths and can be cut to any custom length with scissors or a utility knife before or after shrinking. Buying the 5M roll is generally the most cost-effective option if you regularly rewrap multiple packs or need to cover longer stick-pack configurations.

What is the difference between standard and "Thick" variants at the same flat width?

The "Thick" variants (e.g., 135mm Thick, 165mm Thick, 195mm Thick, 220mm Thick, 258mm Thick) have a heavier wall thickness than the standard version at the same flat width. Thicker walls provide additional abrasion resistance and a more rigid finished wrap, which is useful for high-impact RC applications, power tool battery packs, and situations where the pack may experience physical stress during use.
