Large sized shrink tubing?

Hi guys
Do you guys know a site that sells extra large shrink tubing for battery packs at a good price?
I searched a couple of sites but its smaller than what I need.
My pack is around 28cm long x 11cm wide and 8cm high
Thanks

I bought 200mm wide heat shrink and its ok product. You have 11+8=190mm. Should be just enough.
