Our main business is the assembly of custom special battery packs and as such we have in stock many different sizes of shrink sleeves used to insulate and package different size battery packs. We have been asked on numerous occasions to supply short pieces of sleeves to individuals, clubs and schools for various projects. We put together the following page to assist people to help choose the correct size.

The art of achieving a nice neat job is to choose a sleeve that is the tightest fit around the item and then to apply an even heat, using a hot air gun, taking your time so as not to cause the sleeve to split.

A common mistake that people make is to use shrink sleeve that needs excessive heat to shrink down and not realising that this heat can actually cause damage to the original cells sleeving and therefore exposing potential short circuits. The PVC sleeving we use shrinks reasonably easily.
