Pretty sure if you float the ground you gotta bring all negatives on that circuit to the negative on the battery.
Did you have to trim the divider inside the box? Dimensions of the battery?I bought a AGM atv battery from autozone . Part number AZX 5-L . It was like $80 bucks . Fits nice in the tool compartment of the air box . Cut up some foam or a sponge and line the battery tray so the battery doesn't move around .
About how deep the tray is lol . Sorry I don't feel like taking it apart to measure . I'm going to say around 4.5in.How tall
So you can run the +/- from reg/rect to the +/- on battery and run the - battery to frame and not have to worry about redoing your wiring?
If you ground the battery to the bike you defeat the purpose of floating the ground off the stator
