Product Details
✓👍【 Intelligent Voltage Protection & Safety】 Our smart battery disconnect switch continuously monitors voltage levels. If the battery voltage drops below 11.8V, it automatically cuts power after a brief delay to prevent over-discharge. When voltage exceeds 13.6V (e.g., during driving), the remote control is temporarily disabled to avoid accidental operation, ensuring both safety and optimal battery preservation.
✓👍【 Advanced Energy-Saving Design】 Featuring an upgraded magnetic latching relay, this switch boasts an ultra-low standby current of only 0.005A (5mA). This innovative design eliminates parasitic battery drain during long-term parking, outperforming traditional switches and significantly reducing power loss.
✓👍【Dual Control: Remote & Manual Operation】 Enjoy the convenience of wireless control with a reliable remote range of 30-70 meters, plus a manual override button for emergencies or maintenance. This dual functionality provides flexibility whether you’re securing your vehicle from a distance or working directly on the electrical system.
✓👍【 Robust Build & Wide Compatibility】 Constructed with high-purity copper components and rated for 250A continuous current (1200A cranking current), this durable switch suits 12V systems in cars, RVs, boats, trucks, motorcycles, and more. Its universal design includes adjustable shims for easy installation on both standard and undersized battery posts.
✓👍【 Extend Battery Life & Prevent Drain】 Effectively combat common power drain causes like aging wiring, forgotten lights, or long-term inactivity. By automatically disconnecting the battery when not in use, this switch helps maintain charge levels, prolongs battery lifespan, and ensures your vehicle starts reliably when needed.
