XS Power 554 i-BAR Marine Terminal Adapter Kit
Reconfigure your XS Power battery to fit your boat 5/16″ and 3/8″ studs (top only)
Our take on the XS Power 554 i-BAR Marine Terminal Adapter Kit by Crutchfield's Dominic DeVito
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.
What's in the Box:
- Positive adapter rail
- Negative adapter rail

Overview: The XS Power i-Bar 553 rails mount to any i-Bar compatible battery and provide two top mount terminals each. Two 3/8" stud terminals and two 5/16" stud terminals are included, with wing nuts.
