Whether you're a hobbyist assembling an e-bike battery, a technician refurbishing power tool packs, or a maker working on a custom energy storage project, getting a clean, secure wrap matters — both for safety and for a professional finish.\u003c\/p\u003e\n    \u003cp\u003eThis heat shrink tubing comes in a 475mm flat width, which expands to cover large-diameter battery modules and multi-cell assemblies. Each piece is available in lengths of 1 meter (≈39.4\"), 2 meters (≈78.7\"), and 3 meters (≈118.1\"), and in your choice of Black or Blue. The tubing is made from flexible, electrically insulating material — typically polyolefin or PVC — and shrinks down uniformly when heat is applied, conforming tightly to the surface beneath.\u003c\/p\u003e\n    \u003cp\u003eTypical applications include wrapping lithium-ion battery modules for e-bikes and scooters, insulating bus bar assemblies in DIY power walls, bundling and protecting wire harnesses in automotive or marine builds, and adding a clean outer sleeve to repaired or rebuilt battery packs.
