Thanks Shawn!! I promise I will not use LR, as it was to play with on my USB passthru. With the 401, it sucks down juice fast and tastes burnt it if I use it to fast.
So, it appears you cant use the 501 atty on any 401 automatic batteries. I tried both of mine, and my auto PT, no such luck. The is no airflow moving thru the adapter to trigger it.
Kinda works on the manuals, but I dont think its getting hot enough.
I have two different batteries, one is brand new, just opened with the 501 cartos.
The other is about 3 wks old.
The older one might have had a lower charge, but didnt get much vapor. Its charging now to see if it is just low on power.
The new one gives decent vapor, but I get fluid in my mouth.
I used the condom fill method on the cartos.
I think i just need to practice on filling cartos
Sucked a bit out with a dropper, and seems better, but kinda burning my throat.
Edit:
Ok when you get the fluid just right, and heat the atty up right, it seems to work fairly well
not awesome vapes yet, but it could happen.
