Product Description For PVC Shrink Sleeve:
What is this?
Our battery heat shrink tubing delivers reliable electrical insulation to avoid short circuits and leakage risks for all types of battery packs. It acts as a durable protective layer for battery cells and wiring connections, resisting moisture, UV rays and physical damage to prolong battery lifespan.
Featuring strong heatproof, waterproof and anti-corrosion properties, this PVC heat shrink wrap works stably in various extreme environments. Multiple color choices support easy battery and wire classification management. With tool-free and glue-free heating installation, it provides a convenient and efficient solution for battery pack insulation and protection. This PVC heat shrink tubing keeps cell markings and labels visible after shrinking. It features a 2:1 shrink ratio and flat widths from 7mm to 625mm, fitting single 18650/21700/32650/32700/AA/AAA/ Lipo cells up to large multi-cell packs.
Ideal for LiPO, LiFe, NiMH, NiCd and Li-ion battery packs. Widely used for RC cars, aircraft, robotics, e-bikes and portable power equipment. Available in roll lengths from 1m to 200m.

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.
How to use Battery Heat Shrink Sleeve?
1. Prepare the PVC heat shrink tube and cut it to your required length.
2. Slide the battery or battery pack into the battery shrink tube.
3. Apply heat evenly with a heat gun until fully shrunk..
FAQ For Heat Shrinkable PVC Sleeves:
Q: How do I select the proper flat width for my battery pack?
A: Calculate flat width by dividing your battery pack’s circumference by two. For a 100mm circumference pack, select ~50mm flat width. We recommend sizing up a little to easily slide the tube over the pack before heating. The ø value for each option shows the tubing’s approximate round inner diameter.
Q: Will this tubing fit LiPO, NiMH, and NiCd battery packs?
A: Absolutely. This PVC heat shrink sleeve is a popular protective wrap for LiPO, NiMH and NiCd RC battery packs.
Q: What heat setting do I need to shrink this PVC tubing?
A: The PVC begins shrinking at 70–90°C (158–194°F). A standard heat gun at low-medium power delivers great results. Keep open flame away; it will burn and stain the PVC surface.
Q: Is this shrink tubing suitable for outdoor or humid locations?
A: When fully shrunk, it provides light moisture resistance for mild outdoor use. It is NOT waterproof and cannot be submerged. For constant wet or marine use, adhesive-lined dual-wall heat shrink tubing is the better option.
Q: What shrink ratio does this battery pack PVC tubing have?
A: It has a 2:1 shrink ratio. When heated, it contracts to around half its original diameter. Shrink performance varies slightly per dimension. Always test on spare tubing before wrapping your battery pack.
Q: What roll lengths are offered?
A: We supply rolls in 1M, 2M, 5M, 10M, 20M, 50M to 200M per roll. Available lengths depend on which flat width you choose.
Q: What's the delivery time when I order this heat wrap shrink?
A: We will ship them within 1 week.
