If electric lawnmowers offered the same value, operational convenience, and maintainability (compared to gas-powered mowers) as electric cars do, they'd sell like hotcakes. Two-stroke engines are a PITA.
My father originally had a 100% manual lawnmower, and for the size of our property, it wasn't really bad; my father is a physically fit dude, and he could knock out the whole thing in a short period.
Then in the late 80s, he purchased an electric lawnmower! Yep it wasn't battery-powered, but it had a little AC cord that you plugged in... somewhere! So Dad would just run a ginormous snake of an extension cord out across the lawn.
Now, our property wasn't large, but to reach an AC outlet, we really needed a lot of cord, and of course it was a key skill to not run over your own cord, like when you're vacuuming.
Dad never got anything gas-powered. He also had an edger that was electric, IIRC, and he made a lot of use of this edger. It was one of those kinds that used a fishing-line type cutting edge.
But he kept that machine around, and I guess it was fine for a very long time. Dad and Mom are old enough to employ a landscaping team, nowadays.
I kept seeing YouTube videos of people reviewing electric chainsaws or snowblowers or whatever and apologizing to their core audience that they weren't woke Democrats, it was just a better tool for many uses.
I can see a hedger working - even with a klunky battery making it a bit unwieldy. But chainsaws and mowers need serious torque - don't so don't they need to stay plugged in while you work ?
I also have an EGO mower, and in addition to the advantages you list, I would add that they’re less noisy and you don’t end up breathing exhaust fumes.
I don’t even understand why anyone would use a petrol mower at this point, except for some edge cases like professionals mowing multiple lawns per day.
