Adhesive Fish Paper Insulator Sheet - 70mm x 100mm, 0.25mm Thick, 4-Pack

Protect your battery pack with pre-cut adhesive fish paper sheets designed for clean, reliable insulation during lithium-ion battery assembly. These 70mm x 100mm fish paper pieces are commonly used when building 21700 and 18650 battery packs to help isolate cells, nickel strips, and other conductive areas.

Each sheet includes 4 individual adhesive-backed fish paper sections, making it easy to apply insulation exactly where it is needed without cutting from a roll.

Features

• Size: 70mm x 100mm sheet
• Thickness: 0.25mm
• Quantity: 4 adhesive fish paper pieces per sheet
• Adhesive backing for easy placement
• Helps insulate battery cells, nickel strips, and pack layers
• Useful for DIY lithium-ion battery pack building
• Great for electric skateboard, e-bike, scooter, and custom battery projects

Common Uses

Use adhesive fish paper to help protect against accidental contact between conductive battery pack components. It is commonly placed between cells, nickel strips, BMS areas, pack layers, and other locations where extra electrical insulation is needed.

Battery Builder Note

Fish paper is an important insulation material, but it should be used as part of a complete battery-building process that may also include Kapton tape, fiberglass tape, proper cell spacing, secure wiring, and careful voltage checks before use.
