QS8-S (Female) Anti-Spark High-Current Power Connector

QS8-S (Female) is an ultra-heavy-duty power connector engineered to manage extreme electrical loads in high-voltage DC architectures, supporting continuous currents up to 110–180A and peak surges up to 300–500A. Designed primarily for the battery-side connection of high-capacity power setups.

Featuring massive 8.0mm gold-plated split-bullet terminals, it minimizes internal resistance to ensure efficient, cool power throughput under heavy demands. Enclosed in a rugged fiber-reinforced nylon housing rated for high temperature and impact resistance. Comes with a snap-on rear insulation cap that neatly secures and shields soldered joints without the need for heat-shrink sleeving.
