PVC Heat Shrink Tubing for RC Battery Packs — Durable Wrap for LiPo, NiMH & NiCd Cells
If you've ever had a battery pack with torn, peeling, or missing wrap, you know how quickly exposed cells can become a safety hazard — and how hard it is to tell your packs apart in a busy pit area. RC builders, battery rebuilders, and workshop technicians need a reliable, easy-to-apply wrap that protects cells, keeps packs looking clean, and holds up through repeated charge cycles and rough handling.
This PVC heat shrink tubing is sold by the meter and available in flat widths from 83mm (Ø52mm) to 120mm (Ø76mm) — covering the most common RC battery pack diameters. Each piece is cut from continuous PVC tubing stock with a generally 2:1 shrink ratio. Lengths are available in 1 meter (≈39.4"), 2 meter (≈78.7"), 3 meter (≈118.1"), and 5 meter (≈196.9") options, with 10 color choices including Black, White, Blue, Red, Yellow, Green, Clear, Fruit Green, Silver Gray, and Purple.
Typical use cases include rewrapping worn LiPo packs for RC cars and trucks, rebuilding NiMH sub-C cell packs for vintage RC vehicles, color-coding battery packs by capacity or owner in club racing environments, and protecting NiCd packs used in RC boats and aircraft from moisture and abrasion.
🔋
Compatibility: Designed for LiPo, NiMH, and NiCd RC battery packs. Flat width 83mm–120mm covers most standard sub-C, prismatic, and pouch cell configurations. Confirm your pack's circumference before ordering — see FAQ below for sizing guidance.
✅ Key Features of These PVC Heat Shrink Tubes for RC Battery Packs
-
📐8 Flat Width Options — Sizes from 83mm flat (Ø52mm) to 120mm flat (Ø76mm) let you match the tubing precisely to your battery pack's diameter, avoiding loose wraps or forced fitting.
-
🎨10 Color Choices — Black, White, Blue, Red, Yellow, Green, Clear, Fruit Green, Silver Gray, and Purple make it easy to color-code packs by capacity, voltage, or owner in a shared workshop or race pit.
-
📏Flexible Length Selection — Choose 1m, 2m, 3m, or 5m per order. The 5-meter option is ideal for battery rebuilders who rewrap multiple packs in a single session, reducing per-pack cost.
-
🔥Heat-Activated Shrink Fit — Apply with a standard heat gun for a snug, conforming wrap. The tubing shrinks evenly around rectangular and cylindrical pack shapes, sealing edges cleanly without adhesive.
-
💧Moisture-Resistant PVC Material — The PVC construction provides a barrier against light moisture, dust, and abrasion — helping protect cell casings during outdoor RC use on grass, gravel, or damp surfaces.
-
✂️Easy to Cut and Apply — Standard scissors cut cleanly through the flat tubing. Slide over the pack before shrinking — no special tools required beyond a heat gun, making it accessible for first-time battery rebuilders and experienced technicians alike.

Sizing Tip: Measure your battery pack's circumference and divide by 2 to estimate the flat width needed. When between sizes, choose the larger option for easier installation. The tubing should slide over the pack with light resistance before heat is applied.
❓ Frequently Asked Questions
How do I choose the right flat width size 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 100mm circumference needs approximately 50mm flat width — so the 83mm (Ø52mm) option would typically work. When in doubt, size up slightly so the tubing slides on easily before shrinking. Our sizes range from 83mm flat (Ø52mm) to 120mm flat (Ø76mm), covering most standard RC battery form factors. For a quick reference: 1 inch ≈ 25.4mm, so 83mm ≈ 3.27" and 120mm ≈ 4.72".
What shrink ratio does this PVC tubing have?
PVC heat shrink tubing generally has a 2:1 shrink ratio, meaning it shrinks to approximately half its original diameter when heat is applied. This is sufficient for wrapping most RC battery packs snugly without excessive material bunching at the ends.
Can I use this tubing outdoors or in wet conditions?
PVC heat shrink tubing is generally moisture-resistant and provides a protective barrier against light splashes and humidity. It is not rated for full submersion. For outdoor RC use in light rain or damp grass, it typically performs well. For extended wet-weather use, consider adding additional waterproofing measures to your battery connections.
What battery types is this compatible with?
This tubing is compatible with LiPo (Lithium Polymer), NiMH (Nickel-Metal Hydride), and NiCd (Nickel-Cadmium) RC battery packs. It is suitable for wrapping both single-cell and multi-cell packs used in RC cars, trucks, boats, and aircraft. The flat width range covers most sub-C cell sticks, saddle packs, and hard-case LiPo configurations.
How much length do I need for my battery pack?
Measure the length of your battery pack and add approximately 10–20mm (about 0.5"–0.75") of overhang on each end for a clean, secure wrap. For a typical 150mm (≈6") RC battery, a 1-meter length gives you multiple wraps or enough for several packs. Longer lengths (2m, 3m, 5m) are ideal for bulk rebuilding or workshop use where you're rewrapping many packs in one session.
What tool do I use to shrink this tubing?
A standard heat gun is the recommended tool. Apply heat evenly around the tubing while slowly rotating the battery pack for uniform shrinkage. A hair dryer can work in a pinch but may take longer and produce less consistent results. Avoid open flames, as they can scorch or unevenly shrink the PVC material and may damage the battery cells underneath.
Does the color affect performance or shrink behavior?
No — all color variants share the same PVC material and shrink characteristics. Color choice is purely aesthetic. Many RC hobbyists use color-coding to quickly identify battery capacity, charge state, or ownership in a group setting. The Clear option is useful when you want to display labels or markings written directly on the cell casing.
