There have been many post since 2019, when I joined this forum, about water ingres and battery fitment. Other than the rubber splash guard, extending below the battery interface, Giant hasn't fixed anything about it, that I can tell
In 2020 on the Reign, and then in 2021 with the X, Giant made it worse adding holes for cable routing that leak directly above the battery terminals. They solved one issue, terrible cable routine leading to poor shifting, but created even more places for water to enter the frame.
The biggest trouble, may be that the harness itself is not sealed. Water works up inside the harness, and from there, back doors into the connectors.
As adequate avoidance to ride ending water ingress, I tape up the harness, use dielectric grease, avoid the hose, and dry the bike with a fan after each wet ride. It's part of the deal, as Giant try to figure out what Yamaha, Honda, Kawasaki, Suzuki, Polaris, name 100 others figured out aeons ago, its part of the weirdness of bicycle DNA and its painful.
