## 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.
