What is this?

Choose our battery heat shrink sleeve to add robust electrical insulation and avoid short-circuit and leakage failures in your battery packs. This PVC shrink wrap tubing shields battery cells and wiring joints from moisture, UV light and mechanical impact to lengthen battery life.

Our heat shrinkable PVC sleeves feature strong heatproof, waterproof and anti-corrosion performance for use in tough environments. Multiple color selections support easy wire and battery identification during mass assembly. This Lithium Battery Pack Heat Shrink Wrap shrinks tightly with simple heating; no adhesive required. Cell markings remain visible after shrink.

It has a 2:1 shrink ratio, flat widths 7mm to 625mm, covering single 18650/21700/32650/32700/AA/AAA/LiPo cells and big multi-cell packs. Compatible with LiPO, LiFe, NiMH, NiCd and Li-ion packs. Widely adopted in RC models, aircraft, robotics, e-bikes and portable power gear. Roll lengths from 1m to 200m for flexible bulk orders.

Is there any advantages of the product?

1. Premium Electrical Insulation for Battery Safety
Our PVC heat shrink tubing features superior electrical insulation, effectively preventing battery pack short circuits, current leakage and arc discharge. It serves as essential protective insulation for lithium battery packs, electronic assemblies and power connection systems, greatly improving the overall safety of battery equipment.

2. Full Protection for Battery Packs & Wiring Connections
Exposed battery packs, wires and connection terminals are vulnerable to moisture, chemical erosion, UV radiation and physical abrasion. This battery heat shrink tubing forms a tight protective barrier, shielding battery pack structures and circuit connections, extending battery service life and lowering long-term maintenance costs.

3. Outstanding Environmental Adaptability for Battery Application
Manufactured with high-quality PVC materials, our heat shrink wrap boasts excellent heat resistance, waterproof performance, UV resistance and anti-corrosion capability. It maintains stable insulation and protective performance even in humid, high-temperature, low-temperature and corrosive working environments, ideal for outdoor and industrial battery pack use.

4. Multi-Color Design for Battery & Wire Classification
Available in multiple color options, our PVC heat shrink tubing supports intuitive identification and color separation management for battery packs and connecting wires. It simplifies classification for complex battery wiring harnesses, facilitating daily inspection and equipment management for battery assembly projects.

5. Simple & Efficient Battery Pack Installation
No complex tools or adhesive are required. The heat shrink tube can shrink rapidly and fit tightly on battery packs and wiring components with simple heating via heat gun. It enables fast, neat and professional battery wrapping and insulation construction for mass production and DIY battery assembly.

What should I notice?

Use a heat gun for heating. Move the heat gun continuously back and forth so the PVC heat shrink wrap receives even heat and avoids local overheating.

Sizing tip: Flat width ≈ half of battery pack circumference. Choose a size 5–10% larger for easy installation. Use a heat gun for even heating to get a wrinkle-free, tight clear shrink wrap.
