^^^ That is a serious BEC!!!!
I've been running 2 CC BECs since they first came out with no issues on 4 and 5S lipos. I don't remember seeing any of those threads on problems, but I'm a bit concerned now, not so much about the servos but blowing my Nomadio React receivers which have become pretty rare and scarce to get for decent $$ w/o getting gouged on e-bay. I could easily see a fully charged 5S blow a receiver putting >20v through it.
