That would be a good price, I just grabbed one from sears bc I wanted the lithium ion battery and charger for the c3 impact wrench bare tool I am getting
Yes it is C3 lithium ion; I looked today at my local store and the bottom of the box clearly has a black and white banner with "go-fast" script that says Lithium Ion.
Lithium I never doubted, but without the C3 my concern is that it won't fit in a C3 tool, kind of like Nexus, Bosch, and Milwaukee have essentially identical battery systems and NOTHING fits anything else, tabs etc block use.
