Detailed Product Description

Critical Safety for DIY Battery Packs

When building custom lithium-ion battery packs for e-bikes, drones, or power banks, safety is paramount. The PVC shrink wrap on standard batteries can be easily damaged by heat during spot welding. These Barley Paper Insulation Gaskets provide a secondary, robust layer of protection between the positive terminal and the negative casing, effectively eliminating the risk of dangerous short circuits.

High-Quality Material

Made from “Barley Paper” (fish paper), these gaskets are renowned for their excellent electrical insulation properties, heat resistance, and mechanical strength.3 They withstand the high temperatures of spot welding without melting or shrinking.

Easy Application

Each gasket comes with a strong self-adhesive backing. Simply peel them off the sheet and stick them centered onto the positive pole of your 21700 battery before adding nickel strips.

Key Features

• Perfect Fit: Precision die-cut specifically for 21700 size lithium-ion batteries.
