I bought the first Xrange as well. (I think we've talked before). But I run the 8ah Xrange batteries and yes it's very heavy. I was just on Greenworks site yesterday and they show a 60v Xrange saw with a 20" bar that comes with the 8ah battery and charger and it claims in the description that it's 3.2kw of power. I do believe mine is the 2.5kw, because the model number is 60CS25. You can get the 3.4kw 82v kit from Greenworks commercial right now for $599. But it's only a 4ah battery. When I got my saw, I think they were discontinuing the model because I got the saw, two 8ah batteries and the 10amp dual bay charger (simultaneous charging) all for around $700. I agree with you though, I don't run it very much. I prefer my 40v Greenworks. It's lighter and might be a bit slower but still cuts great. I think I promised you a video... I still want to make a short video demo-ing the cutting speeds of the 40v, 60v, and 80v.

I did a big tree once... got 3/4 of the way through 1 cut and had to go grab the gas saw. Also cut a 1/2 load of pine for our fire pit... a hijet load... ended up switching to the gas saw because... again.. dead battery. Have since sold this saw and gone back to gas. If I'm cutting anything more than a 6 inch diameter tree I get the gas saw out. If I'm limping for the chipper the 20v dewalt chainsaw out lasts this saw, weighs less, and is more portable than the greenworks. I didn't find a single situation where this particular saw was better than a gas or cheaper electric.
