not so sure. becs and fets dont necessarily have to be of different size - they can be of better quality, pick of the yield etc. v2 has a beefed up bec vs v1 without any compromise to packaging.
at this point his design is fine or it wouldnt last multiple runs before failure. there are certain components - fets and becs that arent living up to the ratings that castle thinks they are buying- read made in china.
this is classic - vendor supplies samples to win the bid. they are tested and no issues. then sends 2500 of them that have 10% yield failure.
