Questions For Dual Coil Drip Atty Users

[Rixter]

When dripping, I typically use EmpireMods Premium Bridge Free LR901 1.5Ω atties now, but a couple of months ago, when I was trying out different atomizers, I ordered a couple of EmpireMods Bridge Free Dual Coil LR306 1.5Ω atties to see how they performed. I was not very impressed by them.

I know that, with dual coil cartos, you're supposed to hit them with twice the power because they have two coils. This does not seem to be the case, though, with the dual coil 306 atties. Anything much higher than 4v (roughly 5 watts per coil) results in a burnt taste, and 5 watts or less per coil is just too weak for my taste...at least with these DC atties.

Am I missing something? Are they wired differently than dual coil cartos? Where do you set your voltage/wattage to get a good vape with your DC drip atties?

An EmpireMods Bridge Free Dual Coil LR306 1.5Ω with a Cherry Vapes "The Universal" and Ceramic Drip Tip on a Sigelei Zmax set to 10 watts...5 watts per coil (anything higher tastes burnt).

I always had bad luck with LR attys. They tasted burnt to me. I use higher ohm attys on my VV/VW units and just bump up the Volts.

Yeah, I do prefer SR/HR to LR atties since I have PVs that can power them up to where they need to be, but the EmpireMods Premium Bridge Free LR901 1.5Ω atties perform so well that I continue to stick with them. I have said again and again that I really wish they'd come out with a SR or HR version of that atomizer...I'd buy them in bulk.

I just found these HR 510 DCAs while writing this post, so I may have to order a couple to see how they perform. The same vendor carries LR and SR versions as well.

*UPDATE*

I am now running the EmpireMods Bridge Free Dual Coil LR306 1.5Ω atty on my Zmax at 13 watts (6½ watts per coil, <3 amps) with no ill effects. I hesitate to take it any higher until I get dual 18350s because of the boost circuit's supposed (by Phil Busardo, Steve K.*, & others) amp limitation when using a single 18650.

I don't know what happened, but the burnt taste is gone now and the performance is exceptional. I guess I just didn't let it break in long enough.

Go figure.

* From Steve K.'s "The Variable Voltage and Wattage Sigelei ZMAX Review":

"The reason for dual batteries is simple power. Using a single battery,
the ZMAX seems to be stuck around 2.5a of capacity much like most other
variable voltage devices out there. However, using dual batteries the
ZMAX seems capable of handling loads of 4a or more."
