https://www.acmetools.com/blog/dewalt-battery-compatability/ : Q: I’m UK based and the voltages seen a little different;
my impact driver is 18V for example, while the local shops sell
54V tools and batteries. ... A: ... in the United States DEWALT is able to advertise their tools at the
maximum voltage the battery will put out for a fraction of a second when the tool
trigger is pulled. ... The battery voltages are nominal 18V and 54V.
The rest of the world makes DEWALT note the battery voltage for what it is.
