Barley Paper (Fish Paper) Insulation Rings and Strips are designed to provide additional insulation and protection when building or repairing lithium battery packs.
Manufactured from high-quality vulcanised fibre (fish paper), these insulating components help prevent accidental short circuits between nickel strip, cell terminals and battery pack components. Commonly used in 18650 and 21700 battery pack construction, fish paper insulators provide an extra layer of electrical protection while maintaining a compact pack design.
Suitable for DIY battery builders, professional battery pack assemblers, robotics projects and lithium-ion battery repairs.
