Hey the kit alone is $529 + batteries at $286 x2 + taxes etc. So getting way up there. With no more FCA warranty and chance for FCA to deny warranty on anything related. FCA themselves should have done something like this - but they cheaped out. So we all have to suffer with the puny weak idiotic hidden aux battery. But it is what it is. PITA for sure separately charging.That genesis battery kit doesn't seem like a horrible deal at $600. The batteries alone are probably $400 hahaha.
After desulphating my aux seems much better and ESS kicks in right away. Plus my whole charging system seems to be working like it was designed.
