e-power with dual coils?

[permafrying]

i've killed two riva batteries and im sick of having to get them replaced so i want to upgrade a little, ego doesn't supply enough voltage for me so im thinking the e-power. only thing is will the switch handle the 1.6 ohm dual coil carto's? i like using the boge 2.0 ohm but the dual coils hold more juice so i'd prefer to stick with thoughs if possible, or might try the c.c.v 1.7's

I have an e-power and the 14650 battery in it has a bit of trouble supplying a dual-coil with enough power...

Right off the charger, when it's running at 4.2v, it does an okay job.. But I'm suspecting there's MAJOR voltage sag (This could be confirmed with an in-line voltage meter, i don't have one though) because performance isn't all that great.

You could try it with a 14500 IMR, should fair better.. The thing is the max discharge rate of the 14650 is 1.5C, they are 1050mAh so let's say 1.5A max discharge, after this it's abusing the battery/going to give major voltage sag.

Powering a 1.6ohm dual coil needs a current draw of around 2.3 Amps... the battery simply cannot handle it. It might be OKAY for some people right off the charger, but my 2.0ohm boge spin circles around dual-coils for me, and I'm pretty sure it's because a sole 14650 battery cannot handle it.

You can make a 14500 fit in the epower, by stretching the spring. You could try AW IMR 14500s (I have some on teh way, but haven't tried it), or you could go with a box-mod with enough power to push through these things... without using IMRs you'd more than likely need an 18650 mod, or 14500 in parallel mod

--An 18650 e-power would probably have the juice to push them with the right battery...

I think you nailed it edj...good post.

It's funny the number of users I see posting that they use the DCs on their eGo units and love em. Of course, they have been using 1.5 ohm single coils on them too. So that they use a 1.6 ohm DC doesn't surprise me, it's just that I don't know if dual 3.2 ohm coils, even if they got the amps, would be as good since that's pretty cool.

I like the e-power because of the replaceable battery rather than tossing the entire unit (it's basically like the DIY nicostick type mod that I use). It usually uses protected batteries tho, and the standard ones would trip.

I'd go with high drain at least. A 5v mod with a hefty regulator would be better (also high drain batts).

What I'd love to see is a head-to-head test on
1) an eGo with a DC
2) an eGo with a 1.6 ohm LR atty/carto single coil
3) the same thing on a nicostick using both IMRs and std 14500 (or 14600)

My guess is that the IMR nico would win, eGo close 2nd, std 14500 would suck. Of course, 5v would blow them all away.

maybe ill try the 18650 e-power.. just dunno bout the size. then again i like the boge 2.0 ohms just hate the capacity

 

[Credo]

Definitely go for the biggest battery you can stand to carry around if rocking dualies is your goal, and carry extra ones with you. 18650 IMR...or even a mod that uses the lap-top batteries.

These things blow through the battery charge and the juice fast when they are prime!

I use the 2 Ohm ones with a Darwin between 4v and 5v. I have to top them almost as frequently as I drip on atties to keep them prime. The Darwin is rated at around 1400mah, @ 5v the things draw 2.5 amps or more (registers as 10 watts or so, but probably more like 5w per coil). So in essence, a battery that can run single coil HV cartos for a couple days will only go 4 to 6 hours with the dualies. Good thing the Darwin works well as a passthru of sorts (charges while vaping).

In short...I like the dualies for an occasional treat. For the long haul...there's lots of stuff dern near as good that doesn't need constant topping, doesn't blow through ml of juice as quickly as the other stuff goes through 'drops', and doesn't drain the battery as quickly.

i've been using them on my 650 mah and 750 mah rivas for awhile, stopped recently because i don't have any just a few boge's. im mostly just interested in something with bigger juice capacity, atleast 2ml minimum with 2.0 ohms at the most.

 

[Credo]

Lots of big stuff out these days.
Giantomizers (if you like the CE2 engine)
GV Vison (A clone of CE2 clearomizer but with a huge tank)
The old standby Mega eGo cartos (with some improvements over the years).
Echo 510 (Giant Carto for eGo/Riva batteries w/poly Fill)
They also do colossal sized dual coil cartos now, and SmokeTech probably has the same 'package' with a single coil by now.

Soon to come will be a slate of new large cartos like the Sapphire bottom coil tank, and the Turbine II tank system.

Most of those are going to work fine on Stock 3.7v batteries.

Nhaler carries a bunch of the big stuff, as does GotVapes (and they should be adding lots of new stuff soon).

P.S.
For less than $50 the Boge Revolution V2.x 1400mah looks like a good deal for an all day vape platform. Not sure if will rock the dualies under 2 Ohms. I recently ordered one as a back-up in case the Darwin gets lost or stolen....I'm anxious to try it out

I've seen a few YouTube vids that show people rockin' dualies on them...they don't say which resistance they're using tho'.

You might try a couple of these just to see if the extra mah helps. Bargain Bin
Also the kgo 1100mah (slb ego) batts have a couple of good reviews about holding their voltage well.
Six posted some good info on some batteries. I'll see if I can find it for you.

When I use a duel coil on my 14650 e-power, I get about the same vapor as I do from a ce2. I like that just fine, but I tend to like cooler vapor, and I can see where others might want more.

Edit: Let me put this another way lol. I've used the duels on my 650 ego and my 14650 e-power. There's not much difference, which is what you wanted to know, right?

I can't find that thread from six. Search around a little until you find it. Very good info.

Just so you know, there is a cheaper version of the e power that is built better and was made with dual coils in mind. The Noego 14500 is only 25. Its just for the unit no batteries but it was made to handle dual coils

The NoEgo is the same exact thing as the e-power except for some minor cosmetic changes... and the spring can be adjusted to fit a 14500.

It's the battery that is going to determine dual coil performance. All of the parts in the NoEgo are just rated to withstand the current of a dc carto

I got my package of AW IMR 14500s today, and I made a battery spacer and tested one out in my 14650 e-power with a dual-coil carto; what a freaking difference!

Seems like the battery is the deciding factor

How did you make the spacer? Got any pics?

How did you make the spacer? Got any pics?

Okay.. it was kind of rigged and very dirty, I don't have any way to show but I was looking around my house for hours for something to use... pennies/dimes didn't fit, I ended up using the back plate of a computer's PCI/AGP slots (you know the plates visible on the back of the computer), twisted it up with some pliers into a twisted cylinder until it looked like it would fit, and worked it back and forth until broke apart.. and twisted the left up metal into the 'twisted metal cylinder'. Dropped the cylinder into the tube, dropped the spring on top of it.

You don't have to worry about shorts or anything because you're just completing the negative battery connection.. which completes on the inside of the tube anyways.. so the spacer can touch anything. THIS DOES NOT HOLD TRUE FOR THE POSITIVE END OF THE BATTERY!!! THIS METHOD WILL CREATE A SHORT IF USED THERE!!

It might be time to start thinking about a mod. And, you don't need to spend a whole lot of money to get in to a mod that will pass the amps the DCs need.

I'd recommend anything that can run with an 18650, with the higher capacity you don't have to worry so much about the cheaper batteries not being able to meet current demands. Or if you really wanted to be ready for the triple coils, you could go for a mod using 18650s in parallel... there's actually one for sale in the small-time mod sellers forum, think it sells for a minor $35

Or if you really wanted to be ready for the triple coils,

The triples are no good at 3.7v. They're designed for HV.

I am using the blue 14650's from mad vapes in my box mod with DC cartos and I get a full days vape.
There is a noticeable difference between the 14650 and my Ego's, but not a huge diff.

Of course I am only a moderate vapor, so YMMV.

My 2 cents, go with the 18650 e-power, they are not as fat as the pictures look.

If you keep killing batteries using a dual coil on an ego which I really think people don't realize WILL damage their batteries... Using an e power with a 14650 or 14500 is not going to do any better. Unless you use an IMR 14500. But then again you would get horrible battery life. The only way to go is 18650 or IMR 18650. or my favorite 2 lifepo rcr123a's at 6v.

I really think people don't realize WILL damage their batteries

Capitalized "WILL" sounds like a pretty strong statement and implies that anyone using DCs on an eGo are going to kill their batts immediately. I don't agree. They might damage a mofset, but they probably won't. They will shorten the life of any battery and not just eGos due to faster discharge creating higher demand for a higher number of charge and discharge cycles.

The mofsets used in eGo batts is very sensitive to surges (and really, mofsets in general are sensitive to surges, not just mofsets in ego batts). Popping a coil or just plain burning out a coil (sometimes you don't have an audible pop) causes a sudden drop in resistance. That generates a surge. These types of mofsets respond to surges by failing.

A standard 1.6 ohm DC running at 3.2v would require 2 amps. However, what everyone forgets: Two things: First, a 1.6 ohm carto full of juice is very close to 1.8 ohms. Vape it completely dry and it might get back down to close to 1.6, but the resistance will never be as low as it was before its first filling. - Ohms law doesn't mean anything until electricity is running through the circuit. Loaded voltage for a standard DC on an eGo is right around 2.8v.

What it comes down to is that in reality, you're pulling around an amp and a half or so and not even a full two amps.

eGo and eGo clone batts die all the time no matter what atty or carto has been used on them. Some last longer than others. Some die sooner than you'd expect. The highest risk device you can use on them is a single coil low resistance atomizer because it has the highest likelihood of burning out and causing a surge as it burns out. I think that a dual 3.2 ohm coil carto is a much lower risk than a single 1.5 or 1.7 ohm coil atty or carto.
