If the boards were designed correctly (and as of now I have no data to support otherwise) then the regulator should not be running anywhere near max current, and therefore should be fine.
The 12V from the battery is well within the specifications for input power for the chip (36V max, 7-15V nominal).
Unfortunately the auto reseting breakers will not protect this device as the smallest of the auto resetting breakers are 20 amps and the board is speced for 100mA max normal usage and 140 mA catastrophic current.
Again, as of now, we've only heard of a few failures. Lets take tallies of whats failed and why. At this point we should still be in information gathering mode and not jumping to any conclusions.
