i have always wondered why none of these vendors have ever offered a "plug in battery adapter", a battery case with a cord attached to allow you to run the tool off the wall when it is convenient. it seems that these battery packs should have enough room in them for the size transformer they would need . . . .
i certainly though about playing around with this when one of my batteries went dead in a previous tool system i had. never got around to it, though . . . . . .
Their FlexVolt miter saw has a plug-in option.
Im heavily invested in Milwaukee stuff, but for 239 even Id consider the 7.25" slider.
