18650 Lithium Battery Insulation Ring for Positive Pad (Pack of 10) – Battery Cell Protection Ring

The 18650 Lithium Battery Insulation Ring for Positive Pad is an essential safety accessory designed to protect the positive terminal of 18650 lithium-ion battery cells during battery pack assembly and operation. Made from high-quality insulating paper (Fish Paper/Barley Paper), these rings help prevent accidental short circuits caused by contact between the battery's positive terminal and the metal casing.

These insulation rings are widely used in DIY battery pack building, e-bike battery packs, power banks, electric vehicles, solar energy storage systems, RC batteries, and other lithium battery applications. They provide an extra layer of electrical insulation, improving battery safety, reliability, and overall lifespan.

Whether you're assembling a new battery pack or repairing an existing one, these insulation rings are a must-have component for professional and hobbyist battery builders.
