Exposed cell connections, bare terminals, and unprotected assemblies invite short circuits, heat damage, and premature failure. This 210mm flat width PVC heat shrink tubing is designed for makers, EV battery builders, RC enthusiasts, and workshop professionals who need a clean, secure insulation sleeve that goes on fast and stays put.\u003c\/p\u003e\n    \u003cp\u003eEach order includes a continuous length of PVC heat shrink tubing with a 210mm (≈8.3\") flat width. Available in lengths from 1 Meter (≈39.4\") to 10 Meter (≈393.7\"), and in five colors — Black, Blue, Fruit Green, Transparent, and Silver Grey — so you can match your project or color-code your builds. The tubing features a typical 2:1 shrink ratio, conforming snugly around cylindrical battery packs and cable bundles when heat is applied.\u003c\/p\u003e\n    \u003cp\u003eTypical use cases include wrapping 18650 lithium-ion cell packs for e-bikes and power tools, sleeving LiPo battery assemblies for RC vehicles, and bundling cable harnesses in automotive and marine DIY wiring projects.
