Requirements for drilling holes on the bottom plate of new energy batteries
Best Practice: Holes in studs, top/bottom plates, &...
2x8 double top plates and 2x8 or 2x6 sill plates - 3" max hole diameter, 3 1/2" max to the "center of the hole", and 1'' OC minimum apart. I also found a number of references that non load-bearing top and sill plates can be bored up to 50% of it''s width, and if you go more than 50% the width you have to put on metal strapping.
