Electronics, Lighting, & Gadgets - Heat Shrink tubing

I am looking for some thick walled heat shrink tubing for my battery pack and was wondering if you guys had some suggestions on what worked well for you. The battery pack is a Nightrider that I had to rewire and is 6 AA by 5 AA. It had some good stuff on there and I would like to find something similar. Unfortuantally there is nothing like it where I live and looking on the web does not give you a good idea what it is like. I have been leaning towards some PVC or Polyolefin. Website links would be great.

Here is some heavy duty stuff

I have never used any of these, just noticed them the other day

I bought some stuff from there and it is not quite what I needed but they had a link to the plasti dip which is exactly what I have been looking for. Thanks:)

Try radio shack, Home Depot or any place that electrical contractors shop. It is possible that if you heat electrical tape with a heat gun you will get what you want. BTW, 12v home lighting systems are often uninsulated so insulation might not even be needed in your case.

You can get shrink tubing and other stuff for building battery packs here: www.radicalrc.com They are good folks.
