Today I made a 510 PT using the RCA jack mod. I didn't have a battery connector so I just used an atty. RCA jack mod is great. I have parts coming from MadVapes to make two more mods. I think I may have to use the RCA jack for all of them. I really like the universal connector idea.
Best part is the atty will still be usable after my PT arrives tomorrow.
