SUNMORN Battery Disconnect Switch 12V-48V 6AWG Kill Switch for RV Boat

Key features

• IP66 Waterproof & Corrosion Resistant – Sealed rotary design with reinforced O-ring keeps water and debris out of internal contacts, preventing rust and corrosion that cause intermittent failure. Rated from -40°F to 221°F, vibration-tested for diesel engines and off-road use.
• Complete Kit with 6AWG Cables – Includes 2PCS 6AWG tinned copper cables (1.64FT / 20 inches each), pre-crimped with tinned copper lugs and adhesive heat shrink. Everything needed for a clean install on RVs, boats, and vehicles — no extra parts to source. Rated for 12V, 24V, and 48V systems.
• Red/Green Indicator & Positive Detent – Red/green indicator shows at a glance whether power is on or off, even in dim light, and draws no power when the switch is off. Rotary knob has a positive detent feel that won't accidentally switch from vibration or road bumps. Ideal for campers, tractors, and vehicles that sit for days or weeks between uses.
• Simple Installation & Safety Guide – Installs inline on the positive battery cable with just a wrench — no special tools needed. Stops parasitic draw from electronics, alarms, and clocks when parked. Compact design mounts on your battery box or tongue box for easy access. Safety note: keep away from plastic battery boxes and avoid sparks when connecting.
• Fits Standard SAE Top Post Batteries – Works with standard SAE top post batteries for cars, trucks, and boats. Confirm your battery post size before purchase (fits standard posts, not oversized marine terminals). Not UL or CE certified; for DIY and marine use. Backed by a 1-year warranty against manufacturing defects.
