Umm... No disrespect intended but an 808 carto won't work on a 901 battery connection without an adapter. There's no air flow. The threads are the same but the venting is different.
No disrespect taken... You are absolutely correct... I was meaning 901/kr808 batteries as compatibles... i.e. connections... It has been so long since I used an actual ecig battery that I forgot that people may still use original 901 ecig batts... these days most pv's with 901 connection have the vent holes/slits to suite the cartomizer as well....
I guess I need a good cobweb cleaning in my melon
....
So to add if one does have a 901 ecig battery or non cartomizer compatible one... a good trick (without adaptor) is to file a little slit across the battery connection ..which would provide suitable air passage for cartomizer utilization..
Thanks for the catch.. and by all means never hesitate to correct me
