Thin PVC heat shrink sleeve for wrapping DIY 18650 (or whatever) battery packs, sold per 30cm length, you choose flat width…
The flat width is, well, the width of the flat sleeve, to help you with estimating the sleeve required, I created this spreadsheet for you – simply enter the number of cells (across and up) and it will spit out suggested width and quantity of sleeve to use.
If you want 60cm, buy qty =2 , 90cm, qty = 3, you get the idea.
I will try to always send multiple quantity as a single cut length (qty2 = single 60cm length), if I don’t have a long enough length I will ask you first so please keep an eye on emails (or let me know your preference in shipping instructions).
In theory it should shrink up to 50% across the dianeter, and less than 8% longitudinally, the recommended shrinking temperature is about 100 degrees C, you might get away with a hair dryer, maybe, but a hot air gun/blower is probably better.
Plenty of tutorials on Youtube and Google, not that it’s very complicated.
Remember you have to get it INTO the sleeve, so better to be a bit larger than you think, than too small.
