Battery Wrap Kit for 18650 Cells
This kit supplies 240 pieces of PVC heat-shrink tubing sized for standard 18650 batteries. Each tube has a flat width of 29.5 mm, an inner diameter of 18.5 mm before shrinking, and a length of 72 mm. The material shrinks at 80 °C with a 48 ± 5 % rate and is rated for 300 V across a -40 °C to +105 °C range.
Suited for Rewrapping and DIY Insulation
Hobbyists and technicians who need to replace damaged wraps on 18650 packs or add insulation to tool handles will find the 12-colour assortment practical. Users requiring tubing for larger cell formats or higher voltage ratings must look elsewhere.
Critical Spec: 18.5 mm Pre-Shrink Inner Diameter
The tube must slide over the cell before heating, so the 18.5 mm inner diameter determines fit. Verify your battery diameter is smaller than this value; otherwise the wrap will not install correctly.
