54v batteries from DeWalt

Hmmm... looks like a switchable series / parallel cell arrangement.
And something crossing the construction safety boundary from ELV to LV by 4 volts.
I can see the long running benefit, but ..
Won't the battery safety covers get lost on yr typical building site? Won't labourers get fried by something they thought as cordless so safe? Or burned by a huge lithium battery one bad day going super nova....
Yeah, I've seen some Utube channels mention them, but as 20V/60V (maybe that's a europe vs america thing?) presumably the internal banks of cells can be switched from parallel to series.
Apparently the Mercans use a no load figure & us Brits use a load figure. So 60v USA is 54v GB.
That was my immediate thought. Elfin safety may start imposing rules that may make them unsuitable for certain industries.
ELV threshold is 120 Volts for DC isn't it ?

ELV is less than 50V AC - but 120V DC
Ah, opps. I stand connected ...
But things like the control gear will handle lower current so may be a saving there. There is likely an ideal figure for that.
