Product description
Heat shrink tubing / heat shrink film for battery cells and battery packs. Used to insulate and protect fully assembled battery packs. Provides a durable and safe outer sleeve that keeps the cells in place while ensuring electrical insulation and mechanical protection. The material shrinks tightly around the battery pack when heated, resulting in a clean and professional appearance.
Heat shrink film is commonly used for battery packs built from AA, AAA, 18650, and 21700 cells. It helps prevent short circuits, protects against dust and moisture, and increases mechanical stability during handling and use of the finished battery pack.
