INSULATION RING – 18650 (+) 7P RING

is a precision-made insulating gasket designed for 18650 lithium-ion battery cells used in a 7P (seven cells in parallel) configuration. It is fitted on the positive (+) terminal to provide reliable electrical insulation and enhanced safety during battery pack assembly.

This insulation ring helps prevent short circuits by isolating the positive terminal from nickel strips, bus bars, and other conductive components. Manufactured from high-quality, heat-resistant insulating material, it performs reliably during spot welding and under high-current operating conditions.

Engineered for an accurate fit on 18650 cells, the ring is lightweight, easy to install, and stays securely in place—making it an essential safety component for professional and DIY lithium-ion battery pack builders.
