The i-BAR system from XS Power stands for "integrated-Battery Amperage Rail." The system starts with safe, secure rails that lock into your battery's case, relieving stress on the cables and side connections. You can then use and combine i-BAR adapter kits to configure your XS Power AGM battery to fit a number of different vehicles and a wide range of applications. By adding or changing posts, you can send power to a variety of components without sacrificing performance.

This i-BAR 554 marine terminal kit allows you to mount your XS Power battery to top-mount 5/16" and 3/8" marine stud applications. Once installed, you get convenient hookup with the boat's battery connectors without adjusting the wiring. You can also add a post kit for more installation options. Installation hardware included. Warranty: 1 year.
