I made something like this for a local client, but w much cheaper components, and it’s in a specially designed pelican case for shipping equipment out to customers and then back. I am of the understanding it is not legal to ship batteries that are on. I’m not sure if this applies to NiCd but due to much less regulation around them in general and a better safety profile that is what we went with. It’s heavy. But for this application of shipping specialized expensive equipment it makes sense. For general needs, definitely not.

I think if the nominal voltage difference is less than 9V, it's only subject to prevention of short circuit (to avoid fires). >=9V is on a separate category which requires formal testing and labeling (still not as strict as lithium batteries though).
