Hml650 Retractable Landing Gear Supply Voltage

Just looking for advice before I connect the control unit to the flight pack, now the instructions state that the supply voltage can be 3s - 6s/12v - 22v however a fully charged 6s would probably be closer to 25v so my question is it save to connect directly to a 6s lipo pack?

i know with some parts on quads have a 10% buffer, i had a camera that had a max voltage of 12 but with the 10% could handle 13.2v. You would need to speak to the manufactuer thou to see if they have a 10% buffer, if so then it would actually handle 24.2v which is basically a full charged 6s.
