Needed to enclose my DIY battery banks, and thought I would put the battery cell shipping containers to use. Trimmed them down for my needs. I think they turned out good for DIY/Sort-Of. PlexiGlass Covers soon.
High quality shipping crate so I can see why you put it to good use. Nicely wired and laid out. My only thought is I don't see any battery cell separator sheets used in your build.
