What’s in the package 1 x Battery Switch About this item 【Heavy-Duty Electrical Performance】- This battery disconnect switch is engineered for high-demand applications, rated for 300A in 12V-48V DC systems. The heavy-duty master cutoff is constructed with solid brass terminals, ensuring maximum electrical conductivity and minimal power loss. This design makes the power cutoff switch a reliable component for any vehicle's electrical system. 【Negative Top-Post Compatibility】- Specifically designed for standard top-post batteries, this battery isolator switch fits securely on negative terminals with a 15-17mm diameter. The top-post kill switch integrates directly onto the battery post, creating a clean and effective power cutoff point. Please ensure the distance from the center of the negative post to any obstacle is greater than 12cm for proper clearance. 【Versatile Connection Options】- This battery terminal switch offers enhanced flexibility with two distinct wiring methods. The adjustable battery clamp can be oriented in multiple directions to best suit your cable routing needs.
