DIY battery builders, e-bike enthusiasts, RC hobbyists, and solar storage assemblers all need a tubing solution that fits large-format cell packs cleanly and shrinks down without tearing or bubbling. This 188mm flat width PVC heat shrink tubing is sized specifically for large battery packs and multi-cell assemblies where standard small-diameter tubing simply won't reach.\u003c\/p\u003e\n    \u003cp\u003eEach order includes a continuous length of PVC heat shrink tubing in your chosen color (Black, Blue, or Transparent) and length (1 Meter \/ 2 Meter \/ 3 Meter \/ 5 Meter \/ 8 Meter \/ 10 Meter), so you can cut exactly what you need with no waste. The flat width is 188mm (≈7.4\"), corresponding to an expanded inner diameter of approximately 120mm (≈4.7\"). The PVC material is flexible before shrinking, making it easy to slide over assembled packs, and conforms tightly once heat is applied.\u003c\/p\u003e\n    \u003cp\u003eTypical use cases include wrapping 18650 and 21700 lithium-ion battery packs for e-bikes and power tools, sleeving LiFePO4 prismatic cell stacks for solar energy storage, and re-wrapping or refurbishing used battery modules for DIY power walls.
