Top cap configuration is the same as the PrecisePlus. Solid, no leak, but non adjustable. I did press the center post in another .005 higher to insure contact will all RBA's and tanks, so it shouldn't be a problem. It is cross milled with slots for airflow for those tanks that hang low.
On the batteries, Included are different sized orings and two Palladium plated center posts of two different lengths, so making most any battery fit shouldn't be a problem. With the AW's, you just know you are getting quality and they fit like a glove, so i recommend them first.
We'll be getting more AW IMR 14500's and AW P14500's in on Thursday according to tracking.
