50A / 120A / 175A / 350A quick-disconnect battery connector, 600V, silver-plated copper contacts for high-current EV battery packs, chargers and energy storage systems.
The SB series connector is a field-proven, quick-connect power interface widely used on electric scooters, e-motorcycles, electric tricycles, forklifts and stationary energy storage. Each pole is a fully insulated, touch-proof silver-plated copper contact rated up to 600V, with a spring-loaded latch that prevents accidental disconnection under vibration. Housings are color-coded to prevent voltage mis-mating.
