All the Smart Battery Isolator kits available through this website have been used by us personally and proven through application to be good for automotive, side-by-side, UTV, and marine applications. This True® technology truly does what it is supposed to do. You will find video installation instructions and directions for using these Smart Battery Isolator kits as we have used them. Our hope is to actually make DIYers lives a little easier as we go. Or to possibly provide the best Smart Battery Isolator kit to some of the automotive shops around the United States so that they can, in turn, offer the related services of installation and use of these automotive products.
