Cellpack Blue PVC Heat Shrink Tubing – Professional Finish for Any Li-Ion Battery Pack
Whether you are building a new battery pack or refurbishing an old one, you want it to look and perform like a factory-made unit. The final step is just as important as the first. This blue Cellpack PVC heat shrink tubing provides reliable electrical insulation, robust mechanical protection, and a clean, professional aesthetic — whether you are working on an e-scooter battery, an electric bike pack, or a custom DIY power bank.
Note: Compatibility values are for guidance only and may vary depending on cell arrangement, the use of additional insulation, and the mechanical tolerances of your battery spacers.
Why choose Cellpack heat shrink tubing? (Key Benefits):
- Sold by the linear metre — buy exactly what you need without paying for excess material.
- Three diameters available: 120, 160, and 200 mm — covers everything from compact packs to wide, high-capacity batteries.
- 160 mm diameter – the universal choice — suitable for approximately 90% of DIY e-scooter and e-bike battery packs.
- Compatible with 18650, 21700, and 26650 — works with the most common cylindrical Li-Ion cell formats.
- Uniform shrinkage with a heat gun — adheres perfectly to the shape of the pack without creases or gaps.
- Electrical insulation and moisture protection — reduces the risk of short circuits and extends the lifespan of your battery.
- Cellpack brand – European manufacturer — a recognised industrial standard, not generic material without quality assurance.
Details and Performance
Manufactured from heat-shrinkable PVC with a wall thickness between 0.08 and 0.2 mm, this tubing shrinks in a controlled and uniform manner when heat is applied. No specialised equipment is required — a standard heat gun is perfectly sufficient. The blue colour is not just for aesthetics: it allows for quick identification of packs in multi-battery installations and provides a clean, professional finish suitable for both commercial and personal projects.

Frequently Asked Questions
Which diameter should I choose for my e-scooter battery?
In most cases, 160 mm is the right choice — it covers approximately 90% of standard e-scooter battery configurations. If your pack is wider than 4 cells or you are using thick spacers, opt for the 200 mm version.
How do I apply the heat shrink tubing?
It is simple: slide your battery pack into the tubing, cut to the desired length, and apply heat evenly using a heat gun. The tubing will shrink and conform to the shape of the pack in seconds. No special tools are needed.
Does it work with 21700 or 26650 cells, not just 18650?
Yes. The tubing is compatible with any cylindrical Li-Ion cells of similar dimensions — including 21700 and 26650. Choose the diameter based on the total width of your pack, rather than the individual cell type.
How many metres can I order?
Each unit represents 1 linear metre. Simply add the exact quantity you need to your basket — no minimum order, no wasted material.
Does the tubing provide moisture protection?
Yes. In addition to electrical insulation, Cellpack PVC heat shrink provides mechanical and moisture protection — which is particularly useful for batteries mounted on e-scooters or e-bikes exposed to varying environmental conditions.
