Making KR808D Batteries work with 510 cartos?

[N-Dub]

Here's my problem, all my batteries and chargers an PCC and so on are from V4L and as such are KR808D's. I got sucked into all the excitment about the new 2E r4 cartos from Royalsmokers and ordered the minimum (at that time) 30 cartos. They just got here today and I'm confused. Something somewhere went wrong and I now have 30, what appear to be, 510 2E r4 cartos. I'm not 100% sure they are 510's because I've never actually seen a 510, but it looks like ones I've seen pictures of. The cartos have a protruding thredded post that is narrower in diameter than the thredded post on my KR808D batteries. The cartos also have three airflow holes in the base of the post just below the threads. I've looked around (goodprophets, madvapes, etc.) and I can't seem to find an adapter (KR808 D battery to 510 Cartomizer). I really don't want to spend a ton more $, but man what a waste if I'm stuck with these... Can anyone help?

You need a 901 battery to 510 atomizer adapter. This is because the DSE901 and KR808D use the same thread. Here's one - 901 Battery to 510 Atomizer adapter Not good that they sent you the wrong type of carto though..

I'm not totally sure what you mean by "protruding thredded post that is narrower in diameter than the thredded post on my KR808D batteries." Kr8 cartos are female (Kr8 batteries are male); 510 attys and cartos are male (510 batts are female).

But male Kr8 batteries can marry male 510 cartomizers in six states ... oops, I mean using the right adapter. As for adapters, Papa Lazarou's link to MadVapes is a good one. And Good Prophets also does sell "808/901batt-to-510atom" adapters.
