Sure, if the batteries are large enough. I tried Lowe's Kobalt 80V leaf blower, and only on the max speed setting did it have enough power to pull leaves out of the grass. Unfortunately, on that setting the battery would last ~10-15 minutes, which isn't enough time for the front and back yard. Sure, I could get two batteries, but now costs are rapidly rising, and I'm also draining the battery's useful life at an increased rate.
I want cordless electric gardening tools to be great, I really do. I don't enjoy having to deal with clogged jets in my weed eater's carburetor (Husqvarna 4-stroke, because what the article does get correct is that 2-strokes are obnoxiously loud), nor do I enjoy having to drive out of my way to get ethanol-free gas for them. However, I'll take that over mediocre performance and battery life.
