Hey group,
I designed some boards for a 3-5s battery monitor and a 6-10s battery monitor. I used the clunky/awful easyEDAand ordered through their website, and I'll have the boards and components in about a week.
From there I'll solder it up (all SMD stuff) and report back on the success of this endeavor. I have a single board with the TI monitor chip and an esp8266 based controller on the board to read the data from the chip and broadcast it out via wifi or whatever - the board has room for additional headers if needed as output from the controller MCU.
As of now, balancing isn't on the same board as I wanted to take this problem one chunk at a time. I was going to do a separate board for balancing (controlled by the MCU on the monitor board), so I have connectors setup on itfor that but we'll see. Although the TI monitor chip does allow for balancing - I wanted to separate it out due to heat and current considerations - plus as I said, I'm taking it one step at a time.
Looks like some others on easyEDA have BQ76930 designs that'r pretty similar to mine (of course you only find these things out after you've finished) - the main difference being that mine allows for selecting cell count on the board instead of having to create external jumpers - also, they did a much better job
