I've run a tree trimming/felling business for 10+ years now.
When the Dewalt electric saw came out, I got one for up-in-the-tree work. Much nicer to have instant-on/instant-off when needed.
I do _NOT_ recommend the Dewalt. They have a design flaw, IMHO. The chain drive gear has a left-treaded bolt that holds on the chain retention washer. If the bar gets any little flex and torque when cutting, that bolt gets sheared off. After that happened a few times, I passed the Dewalt chainsaw and on to my father. It continues to work successfully as a light use stand-on-the-ground and make straight-no-stress cuts for some years now.
Cheaper and more robust is the chainsaw from Greenworks. I've used their 80 volt saws for years now without any issues. Can handle almost as hefty a load as my mid-size gas powered Husqvarna. Most jobs, even full large tree removals, I do now without firing up the gas saws.
Pro tip, sign up for emails from Greenworks and wait. At least 2 times a year, anything they sell goes on sale for 25 to 40% off.
