Review: Water proof wrap is neede - On time delivery, works great
Review: Would buy again - I built a battery pack and needed to cover it in heat shrink. The size in the description was perfect for my build, and would buy again if I have to build another pack the same size as before. Thick plastic, good quality, just make sure not to spend too much time in one area, or put too much heat because you are in a hurry LOL. I put a small hole in part of the shrink, but not a problem with the tubing, the problem was me getting in a hurry and using a little bit too much heat :). but you'll have this I guess - just remember to slow down a bit and back off a little on the heat as well, and this wrap will give you the result to desire and deserve.

## Questions & Answers

**Q: is it going to work with a 3.2-inch diameter circular battery pack?**
A: Yes, but choose the right size based on the overall size of your battery pack。

Size calculation formula: width + height (thickness) = size of PVC heat shrinkable tube;
Note: If it is a battery pack, it needs to add 20-30mm to the above formula before it can be installed.

**Q: Would this fit a 4 cell lifepo4 battery? dimensions 7"Dx11.25"Wx8.5"H**
A: Sorry, your battery pack is not available.
If you have a 4 cell battery pack with a single cell size of 7"Dx11.25"Wx8.5"H and 4 cells placed side by side, you should choose 70mm flattened width PVC heat shrink tubing.

Size calculation formula: width + height (thickness) = size of PVC heat shrinkable tube;
Note: If it is a battery pack, it needs to add 20-30mm to the above formula before it can be installed.

**Q: I purchased the 200mm size not realizing how big it was going to be. I'm trying to wrap a single 21700 battery, is there anyway to do that with this?**
A: The 21700 battery diameter is 21mm;
Calculation formula: 21*π/2=21*3.14/2=32.9mm;
So first use the flattened width of 35-40mm heat shrink tube;
The 200mm can be used with the 21700 battery pack, not with the 21700 cell.

**Q: Would this shrink enough for a battery that is 6mm wide?**
A: Terribly sorry! The 32mm PVC heat shrink wrap tube does not support 6mm wide batteries, you need a smaller size heat shrink wrap tube.
