I wonder what would happen w.r.t. regen. I would have to look at the schematic of a boost converter.

I remember reading about this somewhere ... AEVA? Yep. Here's the link
big batteries and step up DC converters - The Australian Electric Vehicle Asn - Page 1
Its a few pages long, and I asked some dumb questions as I usually do. Their conclusion appears to be that the lower battery count and cheaper BMS are not enough of an advantage to offset the added complexity and cost of the boost device if there is regen to deal with.
