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?
