These are
the docs for the 16018.
I actually had thought I could set the LVC voltage and the BEC voltage, but you can't.
I ended up getting an external BEC, from castle and set it to 6v.
I still wish the LVC didn't cut out so soon. When I have it set to Cut Off, I used my voltage meter and I had @ 3.84 Volts per cell.
I wonder if when I run 5S, could I set battery type to 6S? Is that just used for the LVC?
