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 555 multi-top post and side terminal adapter kit allows you to mount your XS Power battery with its standard threaded pad mounts in a GM vehicle with side terminals, while it provides two sets of positive and negative top posts for other applications. Once installed, you get convenient hookup with the GM vehicle's bolt-in battery connectors without changing your car's wiring in any way. Installation hardware included. Warranty: 1 year.
