As SKYYcamel noted, the
threads are compatible, but cartomizers need more airflow. Adaptors are relatively inexpensive and can be purchased from a number of vendors. For example,
www.altsmoke.com carries various adaptors, and
www.vapourcountry.com carries the DSE901 battery to cartomizer adapter.
If you don't want to bother with adaptors and are handy with tools, some folks have drilled a small airhole on the side of the cartomizer to provide the airflow . . . basically, the same little hole that you see on a typical DSE901 atomizer.
Hope this helps.
