How (electrically) conductive is carbon fibre?
 

I'm using lipos in a B44 with the wires 'inboard'. The wires are quite tight between the battery strap and the carbon fibre topdeck. If the heatshrink wears through on the battery wires could I 'short' the battery through the topdeck? (I've modified the topdeck to give a little more clearance).

Thanks in advance.

Depends on it's make up i think. Some is very conductive.

I have had a cell short out on carbon. The outer heatshrink wore away - leaving the positive ring, and negative can exposed. Put it into car, it wasn't aparent straight away - but the smoke 30 secs or so after did give it away!

carbon is used in high performance ignition leads so yes its very conductive its also bipolar:eh?:

Thanks for the info.

A fresh layer of heatshrink and a watchful eye required I think.

The other thing you could do is sandpaper the edges of the carbon and seal it with ca glue. This makes it nice and smooth and stops it cutting into your wires;)

When i used to run the schumacher cars, (the mission especially) i shorted a pack of cells through the chassis. I think a few of us then got a few large stickers and placed them over the cell slots and with some strategic cutting folded the edges around the carbon. It was effective and looked cool too:)
