There's a proper tool for every job. When I lived in suburbia, and only ever used a chainsaw for cutting firewood to length, a corded electric was way more convenient than a gasser. But now I go into the woods and harvest all my own, and my wood lot is a long walk from the nearest receptacle, gasoline power is the best option.
Of course, improving battery tech is always moving that threshold.
We may be there by now. I just got a new Greenworks battery saw. It is an absolute torque monster.
Greenworks Commercial 82V 20" 3.4kW 4.56HP Chainsaw "65cc gas equivalent power". I'm still in the first day of testing. Most of what I have to cut is 6" or 8" or smaller. Fir or oak. It really didn't slow the saw at all. I'll try to get some larger oak cuts soon.
The battery didn't last quite as long as I had hoped. But, perhaps one could make a half a pickup load (level top of bed) with an 82v, 4Ah battery. Anyway, one battery was probably about the same as a full tank of gas in my McCulloch 10-10, and faster cutting than the McCulloch, as well as significantly quieter.
There are options for 4Ah, 5Ah, 6Ah, and 8Ah batteries with single battery weights from 4.57 to 8.6 lbs. There is also an option for a 12 Ah backpack. So far I've chosen to only get the 4Ah and 5Ah batteries to save a bit of weight.
Anyway, if one has recharging capabilities, then 2 or 3 batteries should be sufficient for continuous use. The 4Ah battery recharged pretty quickly, rated at 1/2 hour for a 4Ah battery, 1 hour for 8Ah.
If one doesn't have recharging capabilities, then perhaps a couple of batteries and one could fill one's pickup with wood. Inverter in the pickup? Cut long pieces to resaw?
