I've had a box of clear SmokTech dual coil cartos (1.5Ω) sitting on my self for a long time now.
I'm not a fan of dual coil cartos. I think they're unsafe on most devices and don't perform well on unregulated devices with 3.7 volt IMR batteries. I think they need VV to fine tune the two coils to a satisfactory vape.
Well, now that I have a shiny new VV Grand in my grubby little hands, and I know the notcigs chip will effectively and safely power these cartos and good old reliable juice feeding from a Reo will keep them sufficiently wet, I decided to put one in service and see how it goes.
4.5 volts under load is working pretty well. It's not as good as an atomizer, but I'm getting decent flavor and tons of warm vapor. I'll go ahead and run with this carto till I can't stand it and report back.
I've been tempted to try some dual coils but if the life of them isn't at least a couple days I'm better off staying with my single coils since I have a large stock pile of them.
I just wish I knew if it was something I was doing wrong.
Well, I seem to have the exact same problem Zer0. I've tried the Kanger at 2.5, the Resurrector at 1.7, and Boges at 2 and 3ohms also and still can't get more than a day or so before I want to replace them. Ive also tried different juices and don't seem to be getting as much life as normal. I don't have any advice, but you're not alone. I sure hope we figure this out though. Or better yet, somebody hurry up with our bottom fed rebuildable, lol!!!

Its the juice itself..I used to love tasty vapor juice..waffle and tastyfinger..but within one day the carto would taste stale and yucky. Tastyfinger actually killed 5 901 attys in 5 days. Sadly I had to quit using it. I now diy my juice and my cartos last for weeks! Great performance and taste.

If I recall the 4.2v of an IMR on a woodvil used to give me 3.86 under load with a 2 ohm carto.
I think the VV keeps the load up pretty close to what you set it at unloaded.
So if you setting it higher than 3.9 your running them hotter than you did.
All kinds of REO mods, pair of MB Chalice attys for out and about.
Pair of Zen Sidewinders and other assorted gennys for home.
Thanks all for the tips/info!
