I m looking to upgrade my starting battery to Lithium and wanted to get some recommendations. I will be using it to crank my Merc 250 Pro XS and run 3 Humminbird Solix units (2 - 10" screens and 1 - 12" screen), my mega 360, and my 2 power pole pumps. I added up the amps for everything and 100ah should be sufficient but I could go even higher to be safe.
