The Battery Heat Shrink Tube is a high-quality PVC heat shrink sleeve designed for insulating, protecting, and wrapping battery packs, lithium battery cells, electronic components, cables, and electrical assemblies. Available in 50mm, 80mm, 110mm, and 140mm widths, this heat shrink tubing provides a clean, durable, and professional finish for battery pack construction and repair.

Manufactured from environmentally friendly PVC material, the tubing offers excellent flexibility, electrical insulation, flame resistance, and mechanical strength. With a 1.7:1 shrink ratio, it tightly conforms to battery packs and components when heated using a heat gun or hot air blower, providing reliable protection against dust, moisture, abrasion, and accidental short circuits.

This heat shrink tube is widely used for 18650 battery packs, Li-ion batteries, LiFePO4 battery packs, power banks, e-bike batteries, solar battery packs, DIY battery assembly, transformers, motors, sensors, wire harnesses, and electronic equipment. BDTronics supplies premium battery heat shrink tubing in Bangladesh for battery manufacturers, electronics engineers, repair technicians, and DIY enthusiasts.
