Only saw a post or two about it on AT. I'll check again tomorrow. Yes I hope the batts are cross compatible.
I like the 536 for trimming jobs with mostly 3 inch cuts or smaller and a handful of big cut up to 10 inches. The 540 looks like you could just work through trees even if they have a lot of cuts up to 10/12 inches.
Looks like 540 is it greengreer. We'll know more by the time they are up for sale in the US.
There are definitely a few things like that Deva. I think of as "soft" for a chainsaw, but love the low noise, no fumes at my location - sorry power plant surrounding homes, near instant ready with no pull starting the engine.
It looks like it will perform well. I've used the older 535 batt saw for trimming and loved it. Now this looks powerful enough (from some other videos of cutting I've seen) to be used over a much broader range of my tree work - more and bigger cuts.
Maybe. Boosting power on what is basically an existing saw is a good start. I read a bit of an article about graphene (sp) battery technology coming along the other day but since it listed recharges as only 50 times I thought it was more of a come on article than a real jump in accomplishment.
