Fiberglass Strip Tape 50mm 25M Battery Wrap

Secure and protect your custom battery packs with this Striped Fiberglass Tape, a single-sided adhesive tape purpose-built for wrapping, bundling, and insulating lithium battery cells during pack assembly. Its distinctive fiberglass strip reinforcement gives the tape noticeably higher tensile strength than standard insulation tape, letting it hold cells firmly together without stretching or tearing under tension.

This tape combines a transparent, high-temperature-resistant backing with a strong single-sided adhesive layer, making it well suited for securing 18650, 21700, and other cylindrical cells into fixed pack configurations. At 50mm wide, it’s sized for wrapping full battery pack assemblies in a single pass rather than narrow strip bundling, reducing the number of wraps needed to fully cover and secure a pack. The fiberglass strip pattern adds mechanical reinforcement along the tape’s length, so it resists snapping when pulled tight, unlike ordinary PET or PVC film tapes, and its heat-resistant construction holds up well near components that generate mild warmth during charging or discharging.

This tape is a practical addition for hobbyists and builders assembling custom lithium-ion battery packs for power tools, e-bikes, flashlights, power banks, and other DIY battery projects. Beyond battery pack wrapping, its strength and heat resistance also make it useful for general electrical insulation, bundling wire harnesses, and secure packaging tasks around the workshop. Supplied on a generous 25-meter roll, it offers plenty of length for multiple pack builds or repeated use.
