I had the opportunity to try a Beta version of a new Oregon, battery-powered pole saw while doing some tornado clean up work earlier this month. This saw (due Spring, 2014) is part of the Oregon 'PowerNow' cordless OPE product line. It uses the same batteries, chargers, etc. as their other products.

The assembled saw telescopes from 86 to 123 inches, including the 8 inch bar. It comes with Oregon 90SG chain which is 3/8 low-profile AND narrow kerf, .043 pitch, with the bumper drive links. Smaller chains seem well suited for the battery saws. This is NOT the PowerSharp chain, but conventionally filed/sharpened. (http://www.oregonproducts.com/pro/pr...chain/90SG.htm)
The saw motor is located in-line, just after the trigger handle, and uses a splined, aluminum shaft to deliver power to the cutting chain; not a flexible 'speedometer' type cable. The telescoping shaft is oval, and looks like it is some type of fiberglass or graphite composite material.
The saw can be used with their 1.2, 2.4, or 4.0 Amp-hour, Li-Ion batteries, which all weigh about the same. The 4.0 Ahr batteries have not been released yet, so I was unable to try those.
The guide bar attaches to a cast, aluminum head with a built in brush hook for pulling cut branches loose. The bar is held in place with a tool-less knob on the cover, and chain tension is adjusted by a screw at the end (not from the side). The drive sprocket is held in place with an 'E' clip. The saw uses an automatic oiler (non-adjustable on the model used).
