Know this doesn't answer your specific question, but have you considered lacing your own?
Looks daunting at first but is actually pretty simple.
If you can lace up sneakers and tune a guitar, guarantee you could build your own wheel.
Very detailed instructions: http://www.sheldonbrown.com/wheelbuild.html
Spreadsheet to calculate spoke length: https://www.sheldonbrown.com/rinard/spocalc.htm
The only project-specific tool you absolutely need is a spoke wrench -- truing stand, tension meter, dish stick etc are nice to have but not critical in my experience.
Lace the wheel loosely. Flip the bike and use it as a truing stand. Tension the spokes until they all sound approximately same note, and that note sounds about like a known-good wheel. Mount a baseball card to a stay for measuring wheel trueness and dish. Tweak tension on individual spokes until it all comes together.
I've built half a dozen and they all turned out great using this very low tech approach.
It's a fun project.
Kind of like laying tile for a bathroom floor, you find out it takes some thought and attention but is very doable. And after that every time you take a whiz you appreciate the floor.
Plus, you'll save some money if you lace the wheel, which you can then spend on more battery
