Product Description
The PVC Heat Shrink Tubing 300mm is a wide-format insulating wrap engineered specifically for assembling and re-wrapping custom lithium-ion battery packs, such as 3S, 4S, or larger multi-cell configurations. Featuring a 300mm flat width (approx. 190mm diameter), this heavy-duty PVC sleeve shrinks tightly around battery arrangements when heat is applied, providing secure mechanical protection, electrical insulation, and a professional finished look.
Essential for building custom power banks, robotics batteries, and 12V/24V energy storage packs, this durable PVC shrink wrap combines clean aesthetics with robust cell bundling.
🔥 Heating Tip: Use a heat gun moving steadily and evenly across the wrap. Avoid holding the heat source in one spot too long to prevent uneven shrinking or burning the PVC film.
Technical & Architectural Highlights
Wide 300mm Flat Width: Perfectly sized to accommodate larger multi-cell battery packs and custom configurations (e.g., 3S, 4S, and parallel battery arrays).
Durable PVC Material: Provides tough mechanical protection against punctures, moisture, abrasion, and short circuits.
Fast & Uniform Shrinking: Contracts smoothly upon heating at moderate temperatures for a tight, professional, skin-tight finish.
Professional Finish: Gives DIY custom battery packs a clean, factory-grade appearance while keeping cells securely bound together.
