Dewalt Flex volt Battery

So just heard they have released their new line of batteries. Flex volt 20 - 60 volt battery. Will work on tools between those voltages. though 20 volt tools will get 4 times the run time. The 60 volt will double up to run the new 120 volt battery / corded 12 inch miter saw. I heard this was in the works as the reason i picked up a few of the 20 volt xr tools. This is a real game change for dewalt. Oh and there is an adapter for the 18 volt tools to use the 20 volt bateries too. http://www.lbmjournal.com/dewalt-unveils-flexvolt-battery-system/

I hadn't heard that. Sounds pretty cool I hope they work as advertised

Yep. But their lifespan is only until the first of the next month after you buy them.
