Adhesive Cardboard 18650 Li-Ion Battery Insulating Gaskets – Self-Adhesive Insulation Paper Rings (Pack of 100) in Pakistan

Overview

When assembling custom multi-cell lithium-ion battery packs for power banks, electric bikes, or robotics, battery safety and short-circuit prevention are absolute top priorities. The Adhesive Cardboard 18650 Li-ion Battery Insulating Gasket is an essential safety accessory designed specifically for cylindrical cells. Featuring a convenient peel-and-stick backing, these high-temperature resistant barley paper rings apply directly to the positive terminal end of your 18650 cells. They provide a reliable physical and electrical barrier, protecting against accidental shorts caused by damaged outer PVC wraps or shifting nickel strips during spot welding.

Key Features
