All of Mr Nute's comments are so very true. And there is another wrinkle - if you build your box with a component certified by agency X and submit your box to agency Y, you may have your construction rejected out of hand unless the component maker agrees to resubmit to agency Y for re-certification. This is ok per North American accreditation systems for test labs.
For batteries, once you operate above Class 2 or 3 limits (NEC articles 725, 800), construction requirements will always be based, at least in part, on engineering judgment where the standard is not explicit. And standards cannot possibly address all constructions. Hence IEC62368-1, where North America compliance can return to the wild and open west.

The don't address how the cert house addresses things that are not included in the standard such as NiCad batteries.
