Very intriguing. Just a couple questions:

Are there sources for the actual battery case? (I couldn't find any on-line, other than the marine-type boxes that a typical battery would be stored inside of.)

Being new to LTO technology, is it intuitive how these individual cells connect in series for assembly?

I won't need an actual replacement battery for a year, but it sounds like I can buy these now and not worry about storage for that long? If so, better to make up the battery now, or just store the cells as-is until needed?
