I'd consider it if my gas stuff was less reliable.
Chonda lawnmower has some sort of EVAP system that keeps the gas from evaporating. Add a teaspoon of sta-bil, let it sit the winter, starts on first pull.
Chonda snowblower, a little worse, sometimes I have to pull the bowl, "tickle" the float, and reassemble. Five minutes.
If I were a contractor and used Brand X batteries daily, and my OPE took the same batteries, maybe. But I'm not investing in something I use 12-20 times per season.
I used a corded lawnmower at my cousin's place and hated it. 15 amps at 120V is maybe 2 hp. I'm having a hard time buying that a cordless version would make more power. Maybe it'll cut ok thanks to clever blades or whatever but I can get clever blades for my 20" MTD.
