Kent I may be doing something wrong but I never got good results dripping on a 901 3.7 auto or man batts, I get excellent results dripping a 901 5v however.
For me I have tryed every cart
mod out there except the blue dart and for flavor and vapor production nothing compares to dripping.
I don't think you're doing anything wrong. I was mainly addressing someone who is not likely going to be getting a
mod anytime soon. (well, who knows
Since I've burned out two 510s (one mega) on the 5Volt, I'm only using the 901 atty and cartos on the 5Volt. The ohm rating for the 901 works well with the 5Volt, imo - why would I get a 510 HV atty that performs like a 901 when I already have one of those. lol. And with the hotter mod you can get better flavor on stronger flavors out of the 901 too and more vapor than any other batt on cartos. Note: I still get better
vapor and flavor from the 3.7v Bart with the 510/14500 combo.
However, perhaps because I still 'drip' when topping off my carts, I find no reason to quit using carts with the mod I have - blue foam plug + vent straw mod, that gives me @45 minutes on a Bart or Protege - less than that on the 5Volt. I
have only dripped, and simply don't see a difference great enough to pop off the mouthpiece x times vs. filling the cart well with ejuice basically.
