Measure the total length of your battery pack or cells end-to-end, then add at least 10–15% extra to account for shrinkage overlap at both ends. For example, a 200mm (≈7.9") battery pack generally works well with a 250–300mm cut of tubing. We offer lengths from 1 Meter (≈39.4") up to 5 Meters (≈196.9") so you can cut exactly what you need.

PVC heat shrink tubing typically has a 2:1 shrink ratio, meaning it will shrink to approximately half its original flat width when heat is applied. A 300mm flat width tube will generally conform tightly to battery packs or cylindrical objects up to roughly 190mm in diameter.

PVC heat shrink tubing generally activates at temperatures between 70°C–120°C (158°F–248°F). A heat gun on a low-to-medium setting works best. Avoid open flames, as they can scorch or unevenly shrink the material.

PVC heat shrink tubing provides a moisture-resistant barrier suitable for indoor and light-duty outdoor use. It is not rated for continuous submersion. For harsh outdoor or marine environments, a dual-wall adhesive-lined heat shrink tubing is generally recommended.

Yes. This PVC heat shrink sleeve is widely used for wrapping 18650 lithium-ion cells, LiPo packs, NiMH, and NiCd battery assemblies. The 300mm flat width accommodates large-format packs. Always verify the pack diameter against the tubing's shrink ratio before ordering.

Color choice is typically functional or organizational. Black and Silver Grey are popular for professional builds and e-bike battery packs. Blue, Fruit Green, and Transparent are commonly used for color-coding cell groups or showcasing internal wiring in RC and DIY electronics projects. Transparent allows visual inspection of the cells beneath.

PVC heat shrink tubing in this category typically carries a dielectric rating of up to 600V, making it suitable for most low-voltage battery pack applications. Contact us to confirm the exact rating for your specific use case.
