seeking lipo regulator with low voltage shutoff

hi folks,

I’m tinkering with one of my quadcopters and find myself in need of a lipo regulator that

can handle two cells, with an output of 12v @~200ma and shutdown when the battery hits

cutoff threshold. The boost part is obviously easy but can’t find anything as a all in one.

The only solution I can think of right now is to take the 5v output from the BEC and then

boost that back up to 12v. Not very efficient and I dread to think how much power I lose

with that method.

Many thanks,

Andrew
