I have the 60volt greenworks with two 5ah batteries, 16" bar, hardly ever fire up the big Husky-maybe one a year. Brother has a tiny 12v saw, no idea the make or ah of battery and a 6" bar. Like a little toy- it's a fantastic trail saw with two batteries its in his backpack on sled all winter. If you are on a day trip of area you know it's actually way more than enough for 4-8" stuff. To small for stocking the weekend camp wood supply but a great trail saw. He has retired his Sweed saw forever.
