PVC Heat Shrink Tubing for 18650 Battery Packs — Clean, Color-Coded Protection from 7mm to 150mm
Building or repairing a lithium battery pack shouldn't end with exposed cells and tangled wires. Whether you're assembling a custom 18650 e-bike battery, a DIY power bank, or a multi-cell RC pack, loose cells without proper insulation are a safety hazard and an assembly headache. This PVC heat shrink tubing for 18650 battery packs gives hobbyists, makers, and small-scale battery builders a fast, reliable way to wrap, insulate, and identify cells and bundles of any size.
Each order includes 1 meter of PVC heat shrink tubing in your chosen diameter and color. Diameters range from 7mm (≈0.28") to 150mm (≈5.91"), covering everything from a single 18650 cell to large multi-cell packs. The tubing shrinks to approximately 50% of its listed diameter when heated, providing a snug, uniform fit. Available in 19 colors — including Black, White, Red, Blue, Green, Yellow, Transparent, and specialty finishes like Transparent Gold and Silver Gray — so you can color-code cells, packs, or wire runs at a glance.
Typical use cases include wrapping individual 18650 lithium cells for spot-welded battery packs, insulating bus bar connections in DIY power walls, bundling and labeling wire harnesses in automotive or marine builds, and protecting cable joints in low-voltage electronics projects. The flexible PVC material conforms cleanly to irregular shapes, making it a go-to for battery pack heat shrink wrap applications where a neat, professional finish matters.
