Wrapping a large-format battery pack without the right sleeve is a frustrating guessing game — too narrow and it won't fit, too loose and it won't protect. Whether you're a DIY e-bike builder, a power tool repair technician, or an RC hobbyist assembling custom battery packs, you need a heat shrink tube that slides on cleanly and shrinks down tight every time.
This listing offers PVC heat shrink tubing with a 308mm flat width, available in Blue and Black colorways, in lengths of 1m (≈39.4"), 2m (≈78.7"), 3m (≈118.1"), 4m (≈157.5"), and 5m (≈196.9"). The material is flexible PVC with a generally 2:1 shrink ratio, making it well-suited for large cylindrical or rectangular battery pack assemblies. Wall thickness and recovered diameter vary by application — see variant options for specifics.
Typical use cases include wrapping 18650 lithium-ion battery packs for e-bikes and scooters, insulating LiFePO4 prismatic cell assemblies, and protecting NiMH or lead-acid battery rebuilds. The color-coded options also make it easy to distinguish battery packs by voltage or chemistry in multi-pack setups — a practical touch for workshop organization.

Measure the total length of your battery pack and add at least 10–15% extra for overlap and heat-shrink contraction. For example, a 200mm (≈7.9") pack typically works well with a 250mm (≈9.8") cut length. Available in 1m, 2m, 3m, 4m, and 5m rolls so you can cut exactly what you need.
PVC heat shrink tubing generally has a 2:1 shrink ratio, meaning it shrinks to approximately half its original flat width when heat is applied. The 308mm flat width typically yields a recovered diameter suitable for large-format battery packs. Contact us if you need to confirm exact recovered dimensions for your application.
PVC heat shrink tubing provides good moisture resistance for general indoor and semi-protected outdoor use. For prolonged outdoor exposure or submersion, a polyolefin or adhesive-lined heat shrink is generally recommended for superior weatherproofing.
This PVC tubing typically activates at around 90–120°C (194–248°F). A heat gun on a low-to-medium setting works best. Avoid open flames, which can cause uneven shrinkage or scorching of the PVC material.
Yes. This large-diameter PVC heat shrink sleeve is commonly used to wrap lithium-ion, LiFePO4, NiMH, and lead-acid battery packs. Always verify the recovered diameter fits your specific pack dimensions before ordering.
Cut the tubing to your desired length with scissors or a utility knife. Slide it over the battery pack, then apply even heat with a heat gun, working from the center outward to avoid air pockets. The tubing will conform tightly to the pack surface for a clean finish.
PVC heat shrink tubing of this type is generally rated for low-voltage applications. Contact us to confirm the exact voltage rating for your specific application before use in high-voltage systems.
