What?

I just put a meter on it right now. 5.4 volts, lt set at 5.5. Carto tested at exactly 2.5 ohms.

And I just did the same thing. Measured my Ohms on a ProVari, and my multimiter. Brand new 2.5 ohm cartomizer in a tank, was only able to get 5.0 volts.

This is a Dual Coil 2.5 ohm cartomizer.

It's a matter of amps. Not regulation, exactly.

OK, so I'll give this a go...

You can use a dual coil, a single coil, or a deci-coil (10 coils). The unit doesn't even know how many coils are on the atomizer/carto. All it knows is the resistance it is finding.

So use an ohms law calculator and find out how many AMPS you require @ a particular voltage and ohms. Or plug in 2.5 amps and a voltage and see how many ohms you need (min). If you want 5 volts, plug in 5 volts and 2.5 amps (the LT's limit) and see how many ohms that is (2 ohms).

Ohm's Law Calculator

So a 2.0 ohm DC, or a 2.0 ohm single coil will work at 5 volts... mathematically.

So, when you exceed the 2.5 amp limit of the regulator, the voltage suffers (drops). This may also be part of the short circuit protection... but is also a design limit.

Of course, it matters to YOU... a 1.6 ohm DC has two 3.2 ohm coils.... and needs twice the amps. OTOH, at 5 volts a sigle-coil atty/carto usually rocks anyway. Don't really need DCs IMO.

Just remember that it's amps that count here. Amps are determined by the atty ohms (as well as what the battery can provide).

Bottom line is: DCC's are a waste on an LT. I vape my 1.5 ohm DCC's at 4.7 volts, which really brings them to life. I would hate to deal with this type of limitation.

Yes, I agree...IMHO the best carto for VV is a 3.0 ohm Boge, period...from my personal experience on NUMEROUS vv devices.

Did something happen to your lt? Batteries giving out? In your review on your website, you state you got 5.5V with a 2.5 ohm cart.

I actually think my battery was around 3.7V when I recorded the 5.4, put a fresh one in and I'm getting 5.5. But no higher.

And I just did the same thing. Measured my Ohms on a ProVari, and my multimiter. Brand new 2.5 ohm cartomizer in a tank, was only able to get 5.0 volts.

I will do a double check later this evening. In my review, it was a single coil 2.5.

Managed to get a 5.3v out of my 2.5ohm DCC...but that was it with a fresh bat. So...I suppose that a DCC at 2.5ohms may give you 5.5v, but I still prefer single coils when vaping that high. And yes, I still enjoy the lavatube, the mini tube, and hopefully my soon to arrive stainless steel vtube. :)

So, I just pulled out my old ego-t battery after months and threw the 1.5ohm dca from cov onto it. Damn, did that thing kick!

It almost made me want to stash the LT away...

Guess my 306 is just dying. I just ordered a 3.5ohm io6 and a Siam drip tip. Hopefully when that arrives, it'll be a game changer for me.

I'm curious to see how a 3.0ohm dca will perform now on the lt. The whole dual coil on the LT debate is still making my head hazy, but I suppose that theoretically, I'd stick under the 2.5a limit with one of those.

A 3ohm carto/atomizer should put out about the same vapor as a 1.5ohm DC..a 4ohm should put out about the same as a 2ohm. I compaired my 2.5ohm CE2's side by side with a DC 1.5ohm on eGo's and couldn't notice a difference. I think the only real advantage to DC's is having 2 wicks to feed the juice so there is less chance for it to run dry.

Then there is the big downside that you need more amps to drive them to the same watts..so that means less battery time and pushing the limits of batteries more. I don't have many wicking issues with my CE2's though and when I do it's easily fixed in a min.

We should soon know what the new LT will be like and it sounds like more amps so dual coil user should be happy with it. I'm sure you could sell your LT after they come out or just keep it as a 2nd device. I plan on buying another LT in the future :)

The Lava Tube will knock down the voltage on all DCC as a safety feature. You can set it to 5.0V, but you are only going to get an output of about 3.5v-3.7v. You will notice much less vapor production with the DCC on the LT. Grimm Green has a really good video on youtube about the LT.

I think that is only with low resistance dual coils..you can get them in 3ohm...

You are correct. It's a big limitation of the Lavatube and why I would not recommend it. And the popularity of 1.5 ohm dual coil cartos tells me most vapers who try them on a good PV, love them. Just like they are a waste on a lavatube, for those who like cold vapor with little throat hit, they are also a waste.
