Watch the project farm video of battery powered chainsaws on YouTube. Dewalt performs better. I have a dewalt with the 16” bar, it has plenty of power, actually a lot of power. It’s best used for limbing and clean up. They are very handy. If you’re going to be logging, I’d pass on them.
If that’s the video I’ve seen, it’s several years old, unless it’s been updated.
These tools change quickly in that time frame.
