I've been digging around and researching various BMS systems and have come to the conclusion that "BMS" is a catch-all term.
Anyway, I am moving forward with the design started by Stuart and forked on Github by Colin. I considered putting this in my build thread, but thought it might better go under the BMS section as this is specific to BMS. In researching the DIY vs Batrium BMS I ended up here because it seems to be one of the most complete, but not finished, and well documented DIY designs, and I have a soft spot for the AT chipsets. I've used the ATTiny85 on projects before and can muddle my way around Arduinos pretty well. This system, as of Version 2.1/3.0 can provide cell monitoring and balancing. I am using the "smallerpcb" branch under Stuarts github for my board and the software from Collin's fork as he has implemented the balancing function and web interface.
PCB's were just ordered through www.allpcb.com which seems to be one of the commonly used board sources for others building these. Vary reasonable on prices. Others who have used them seem to have good results.
What I really like about this approach is the cell level monitoring/balancing ability, it is developed enough to be functional, but still has room for tinkering and improvements. It is low cost, but should be more robust than the chinese (bms)protection boards.
I think I'm as excited about getting back into this level of electronics as I am about building my powerwall.
