I don't have a lot of cordless tools, just a drill and an impact, DeWalt. My wife got a DeWalt weed whacker and loves it. It's pretty badass and on a town lot its all you would need. I have 900ft of fence I trim around, my little orchard and 2 large embankments and about 20 trees. Either need 2 or 3 batteries (9ah, big moolah) or a gasser. I've been using a Stihl fs38. The cheapest one they make and while I'm not in love with it, it's probably 8 years old and keeps taking the abuse. Battery technology has come a long way. Neighbor up the road who has a smaller, half acre or less, lot, has a robot mower. Husqvarna. Thing mows nonstop even in the rain. It knows when to head back for a charge. His lawn looks perfect, no ruts or windrows of clippings ever. Interesting times, especially since my first drill was chrome!
