Obed, I bought my wife and grandson a
Greenworks cordless chainsaw. I know, I know. . . that sounds like a toy, but the darn thing is really pretty cool. You don't have to add fuel or pull a rope. You do add oil. It has a 40 volt Li-Ion 4AH battery. I charged ours up and then used it to cut down and trim/buck three 6" trees in our yard this last fall on one charge. I charged the battery and it's been hanging in my wellhouse all winter but still shows 3 of 4 power lights on the battery. Oregon makes several replacement chains and bars for the saw. It's a lightweight saw that can get some real work done even if it won't make the chips fly quite like your Stihl. The reviews are almost all positive. Of course, it's pretty expensive, but you never have to buy/mix fuel when you want to trim a few limbs without dragging a cord behind you.
