A deer hunting magazine had a test of the Husqvarna 120i battery chain saw; 36 volt, Li-ion battery. I won't go into all the details but the writer gave it high marks. No gas to mix, no fumes, light at 6.6 lbs., with plenty of power. I'm sure there is more info on the Husqvarna website. I have a corded Harbor Freight saw that I use in the shop for cutting wood for turning pieces. Works OK for what I use it for. Let me add it was very cheap with a 20% off coupon. Sometimes HF will send flyers with a25% of coupon for one item.
