How much of that weight is the essential weight of the battery, and how much is consumer-friendly outer shell, electronics, other one-offs etc.? I.e. if you wanted to take the same tech, put it in a non-consumer-facing context (say a grid-scale battery) and wanted to make it 100x the capacity, would it be 100x the weight?

I can imagine a lot of the weight of the battery unit itself isn't necessarily the battery, if that makes sense.
