I for one welcome advanced battery tech and the devices to make use of it. Wouldn't bother me a bit to have a range of different sized chainsaws that I can keep the batteries charged up with my solar panels. Eliminate liquid fuel and all the hassle and points of failure? You betcha! Wouldn't bother me at all to stop worrying about arcane seal leaks, metering levers, diaphragms, tiny bits of crud plugging up carb intricacies, gas going stale in two weeks, pistons eating up cylinders and vice versa, and all that mechanical weakness failure rot.
And the sooner they get out there, better battery powered devices, the sooner they get better and drop in price. Electronics-generally speaking- is just much faster in the global development cycle. Ten years to one over liquid fuel devices, some bignum like that. Eventually they will hit parity in power and onboard energy storage capacity--then they will surpass liquid fuels..and keep going after that. Not if, just when now.
Fuel burning devices always seem to always go up in price. A lot. Every year. I don't know why that is, but battery powered whatevers, I mean, you name it, anything that can run from a battery, gets better/faster/cheaper every year, and fuel burners just get lots more expensive and only marginally better, if that.
And I don't know if husky makes one, but stihl has a new advanced battery powered saw as well, so they are covering their bets on the tech. Because they ain't dumb.
Electric motors got "torque" from one RPM. That's the powerband-ON. There's a lot to like about electric motors over reciprocating engines.
