Heatshrink tubing for e-molis?

[BrianG]

I've been looking for heat shrink tubing to cover my 2s2p emoli pack and can't find a direct online retailer. I need it big enough so it will go over 2 stacked batteries in height and cover the batteries lengthwise (so the terminals are covered). Considering each cell is 26.5mm in diameter and 70mm long, and I am stacking them two high, this means the pre-shrunk tubing has to be at least 75mm long X 55mm high, or about 85mm diameter.
