I bought a kobalt 48v pole saw this spring. I keep it in my golf cart most of the time and use it a lot, used it this morning.
It impresses me every time I use it and I've never run the battery down on it. It lasts longer than I do when I use it.
I haven't cranked my stihl chainsaw since I bought the pole saw. I cut a 8" oak limb that had fallen on my son's work van the other day, went through it like butter. If the weather ever cools off maybe ill use it long enough to run the battery down, but I have my doubts, its pretty badazz
