This is the best shrink tube we have found for protecting 18650 battery packs. Comes in 3 different widths and is very easy to work with.

Very durable and adds an extra level of impact resistant.

Use a heat gun or blow dryer to apply. 

For rectangles, take the two smallest dimensions, add them up and that is the size shrink you need. So for a 11x3x4" battery, it would be 3+4=7" needed (size small). Then get whatever length of that shrink you need, plus add a couple extra inches on either side. Probably best to double the length in case you mess up you have enough for a second try.




1. Is the size measured flat or by diameter?
2. Is the size before shrinking or the final diameter?
3. How much does this shrink down?
4. Do I need a special heat gun to use this?
5. Are other colors available?



1. This large tubing is measured flat.

2. The size is the measured before shrinking. 

3. This tubing has a 2:1 shrink ratio.

4. No a normal hairdryer will do the job. We do not recommend  using an open flame from a lighter or torch to avoid introducing excessive heat to the battery pack. 

5. At this time the tubing is only available in black.
