What Voltage Does a 20v Max Battery Cut Out : r/Dewalt
15.3v is the voltage at which a Dewalt 20v/18v Lion battery pack is considered ''empty''. The built in 3 LED fuel gauge is lights out below 15.3v. I am also waiting for a low voltage cut off to arrive which I intend to set at 15v. I am putting that in between the 18v /20v pack and a car cig plug so I can use 12-24v USB and USB-PD supplies
