Cross-checking my ideas for my Battery v2 after Battery v1 Nighmare

[silverstone]

--> prefer that one.

Because I didn't want to wait, I used some treated pieces of wood between 2 studs in my office behind a gipps panel.

Used galvanized screws for outdoor use, category C4. Hopefully it won't fall off. Definitively not wet, humidity should be around 50-60% I guess (between 2 rooms, NOT outdoor walls).
