My 36V chainsaw (with a nice new blade) happily slices 14" willow
trunks, it says it's 1100W max.

yes. That sounds about right. First of all this is maple. Its hard
stuff. More than that its been fallen all over winter and has dried
out. Finally 'having trouble' mean its slow...oh the chips are flying
out all right, but each cut takes a minute, not 5 seconds like smaller
stuff.

And can your cordless keep that up for two or three hours to section a
full sized tree?

I'll give the blade a sharpen and see if I can get near to finishing the
job today. Then it's on to easier stuff. 5m yews and Hornbeams that
haven't been lopped in 7 years...
