Not without an adapter. As far as I know, the 901 and KR808D-1 threading is the same. The problem is the air access for the cartomizer. I believe you must use a 901 to KR808D-1 adapter like I linked above to use Vapor4Life cartos on a 901 - not to fix the threading but to provide the air notches needed to be able to let air get to the bottom hole of the cartomizer. I believe if you screw a Vapor4Life carto on a 901 battery without the adapter then it will fit but you will not be able to suck air through it.
Alternately, you could replace your 901 batteries and use KR808D-1/Vapor4Life batteries which can use both the Vapor4Life cartos AND the DSE901 atomizer with no adapter.
