Real-time Voltage Monitoring and Intelligent DisplayTrack the battery health status at a glance! Our battery disconnect switch is equipped with a large transparent LED digital display that shows the real-time voltage. The upgraded matte screen is scratch-resistant, reduces glare, and is easy to read in various lighting conditions. When the circuit is active, it automatically powers on (using only about 30mA), and when disconnected, it completely shuts down without consuming power.

High-power System Heavy-load PerformanceDesigned for reliability under extremely high loads. This sturdy switch can withstand a continuous 12V current of 250A, with a peak tolerance of 300A for 30 minutes. This superior high-current rated performance ensures the safe and stable performance for applications with high demands such as recreational vehicles, trucks, marine engines, and vehicles with high-power audio systems or winches.

High-quality Materials and Safe ManufacturingCrafted for durability and safety. The casing is made of flame-retardant nylon 66, which is more durable and stronger than ordinary ABS plastic. The key internal components use silver-plated copper contacts and terminals, featuring excellent conductivity, excellent oxidation resistance, and a longer lifespan, ensuring reliable power switching.

Flexible Installation and User-friendly OperationSimple and multi-functional design. The terminals on both sides can be adjusted and rotated to fit different angles, making installation in narrow spaces easy. It can be installed with standard 1517mm (0.59"0.67") top-column batteries (please confirm the size of your pole). The operation is simple: turn clockwise to open, counterclockwise to close, achieving complete power isolation.

Multifunctional Unattended Vehicle StorageThe ultimate solution for battery protection and safety. Perfect for cars, recreational vehicles, boats, trucks, and seasonal vehicles. By completely cutting off parasitic power consumption, this switch extends battery life and ensures reliable startup of the vehicle after long storage. It also serves as an essential safety main switch during maintenance, bringing peace of mind and security.
