Project Farm has a couple good videos on battery saws (below). Further, there are plenty of arborists that use them when climbing for smaller stuff like initial limbing.
I have mostly gas equipment in my shed, but I also have a couple Greenworks 48v pieces that I use for the simplicity, and I've been very happy with them. I don't need to strap on a backpack blower and deal with gas, pull start, noise, etc. just to blow grass trimmings off the sidewalk. I just grab the battery handheld off the wall and it's done before the backpack blower would even be warmed up. Likewise, (as others have mentioned) I don't need my 99cc brute saw to cut something small when a 30cc will do just fine and is less wear on me physically.
Sometimes it's also just nice to pick something up and have it "just work" vs having to deal with rotten fuel lines, hard diaphragms, etc. I say this as someone who repairs/rebuilds small engines as a hobby.
+1 to that. Used to repair utility equipment (Hi-Ranger/ Versalift etc.) and number one tool was to talk to the operator rather than the manager.
Funny how often "tool" and operator are synonymous
Joking aside, good on you for getting to the root of the problem(s).
