How many volts? See Squirrel's post. State of the art these days is 80v. That's what seems to get translated into torque at the blade.Bought a new snow blower this year. Battery powered. Worked great till the batteries died. Ego Power w/ 2 7.5 Ah batteries. Supposedly enough to clear 18 car spaces with 6” of snow. I have three spaces. I didn’t move the cars, so 2 spaces including over shooting into the grass in case we get allot of snow this year. Guess I’ll be giving Ego customer support Monday.
