Has anyone here done commercial lawncare? I mowed cemeteries and churches for 5 years. Electric tools might work for a tiny suburban plot but try doing even a single cemetery with them. We only used leaf blowers at the cemeteries a few times a year (Memorial day, etc.) but there is no way an electric blower would last long enough.
D.C. has Arlington Cemetery too, so I'm not sure what they'll do. Maybe they have an exception.
Power density for batteries has been changing immensely, especially at the consumer level.
There are products now where you could easily get through a work day by swapping out for a charged battery two or three times. The extra batteries are a bit of a cost, but in a professional context could pay for themselves with saved gasoline.
