We have lithium battry powered chain saw. It is not the same heavy duty construction of my 50 cc gas chain saw though.
It performs well but after about the tenth use something happened to the battery and would not charge. Lowes graciously replaced it.
The little saw was only 179.00 but an extra battery was 100.00. Seems there are still some things with Lithium Ion batteries to be sorted out.
Two years ago a husband and wife, small business was selling these batteries, in Goshen, Ind rally. One battery to replace my four 6 volts was about 4,400. I seem to remember and weight less than one. A new charger and controller was about 1,100.
Quoted life of battery and no hassle of maintenance sounded good but I guess we are glad to have waited.
Within five to ten years they should be affordable and more reliable. I'm not to thrilled about the idea of a Lithium Ion bomb, in one of the bays. Anytime you pack a lot of energy in a small container, if in the form of a battery you face problems with heat and possible run away discharge, or faults between cells etc that can make for a very energetic bang of now. In the Army we had batteries on helicopters that were nickle based. You could replace indivdual cells and tey weighed next to nothing and were small. It's been so long I don't remember voltages and number of cells. I don't remember very many instances of replacing them. It took quite a bit of power to spool up the engines on Hueys especially the later G and H models. Cost is the reason they weren't used in autos.
