So how did you solve the problem I mentioned above where a BMS fuse link could blow and you would never know, thus allowing that cell to operate without the BMS?

How would the v1.3 be any different?  Not sure if that's what you were implying.
 
I get what you are saying... My application does not really have me too concerned with an issue here.
 
  1. It’s a small battery pack with 13 boards max
  2. All cells are matching (LG modem batteries)
  3. The load power requirements are extremely low… DC fridge which draws about 2-3 amps max.
  4. All cells charged in parallel / equalized before insertion.
In terms of making sure the balance traces are healthy... I did periodically check the trace for continuity during assembly and testing.  I figure that should be sufficient.
