I think it is only rated for 125 C
Hi,I'm wanting to shrink wrap a small board and single cell lipo with glue lined shrink wrap.I'm worried about the heating needed for the shrink wrap. What is the max external temperature a lipo can take?If I use a temperature of 180 degC it shrinks to size within 30 seconds. If I use a temp of 100 degC, it takes three or four minutes.Is it best to do it fast with high heat, or slow with low heat?Thanks for your help,Dee.
Definitely fast with high heat, then as soon as its shrunk chill it with cold air. That way the depthof penetration of the high temperature will be much less. You could pre-chill the cell in the fridge firstfor extra safety.
There is a low temperature shrinkwrap that manufacturers use to make up lipo packs.Works around 80 C.Google should find some.The glue lined stuff is not used, it retains heat much longer until it sets.
The epoxy used for float sensors sounds like a good idea for waterproofing.
