0v batteries are $250.
Anyone who uses battery powered tools fit anything knows you don’t have just one battery, one is charging, one is being used (at a minimum, I have a Milwaukee 6 place charger)
So you have $500 tied up in batteries.
You can buy a stihl chainsaw with twice the nuts and half the weight of that battery saw for half the price of the batteries, and we haven’t even gotten to buy the actual dewalt saw yet
I have the 40V dewalt saw. I love it, when it works. There is a cheap retaining ring holding the chain on the drive that has come off twice on me now. but I've taken down both a 40 and 50 year old sugar maple and pine with it and it is very comparable to a similarly sized homeowners gas saw. about the same weight as well.
I was surprised by how well it cut and how long it lasted. Can cut a full 6.5 foot bed of oak on 1 charge. that's plenty for me. it has it's applications.
Con's are needing more batteries depending on your application and cost. and they aren't going to match an MS-R462 or anything, but in that 12-16 inch range they're pretty comparable.
No fumes, instant on and off, no mixing. though mine leaks bar oil quite a bit, that's kind of a pain.
