Has anyone ever added a second battery to a '18 Legacy? I've seen a battery relocation kit (https://iwireusa.com/products/battery-relocation-kit?variant=41815255449753), but nothing for adding a second battery. My rationale for exploring this option is that I may be sitting in my car for a while, processing and downloading pics, and want to be able to power extra accessories (laptop, tablet, lights at night) and don't want to run down the primary battery. Thank you for your help! Doug
