I think I understand the history. I need to have a few for myself, (I'd
like around 20) but beyond that ....
It seems ultimately we should make a PCB gerber file and opensource it for v2?
Seems a reasonable start.

The MiniBMS system was originally started as an open source project
by users of the DIY Electric Car forum. It was mostly spearheaded by
Dimitri, with input from several interested users. The first version
as intended to be able to used with all the cell modules on one PCB,
with voltage sense wiring going to each cell. It could also be cut
into individual PCBs and cell-mounted. There are vestigial PCB traces
for the opto interconnection even on the v.2 cell modules from this
design (I cut those traces off individual boards, as they add to the
creepage problem). A 4x4/16 cell PCB was standard, but other
configurations were possible.
After the basic system was designed by the group, and Dimitri had a
few runs of v.1 and then v.2 boards printed and stuffed, he decided
that the project was no longer open source, and took it private, much
to the dissatisfaction of the other participants. It wasn't a lot
after that the he sold the intellectual property rights and name to
EVPower, who further refined the design and packaging.
I agree that we have a chance to reintroduce a good portion of these
available cell modules to the EV community for those who are
interested. How shall we procede?
