INSULATION RING – 18650 (–) 2P RING

is a precision-engineered insulating gasket designed specifically for 18650 lithium-ion battery cells in a 2P (two cells in parallel) configuration. It is installed on the negative (–) terminal to provide effective electrical insulation and enhanced safety during battery pack assembly.

This insulation ring helps prevent accidental short circuits by isolating the negative terminal from nickel strips, bus bars, and nearby conductive components. Manufactured from high-quality, heat-resistant insulating material, it can withstand the heat generated during spot-welding and operate reliably under high-current conditions.

Designed for a precise fit on 18650 cells, the ring is lightweight, easy to install, and remains securely in place, making it an essential safety accessory for professional and DIY lithium-ion battery pack builders.
