Best hassle-free tank for Riva?

[Brachinus]

I love my Riva, but my 901 carts with PTB tend to dry out after about half an hour of vaping.

Not a problem most of the time (I don't mind refilling it from a tiny bottle I carry), but my wife and I like to take long road trips on curvy roads (in our Miata), and I don't want to deal with the hassle of refilling while driving.

Is there a good tank that works with the MOSFET battery (and the Riva threading), lasts a whole day (or at least for hours), and ideally doesn't require a syringe for refilling? Something that pretty much "just works"? I don't care a whole lot about flavor or throat hit, as long as I can get some vape in my lungs for hours at a time without intensive maintenance.

have you tried dual coil cartomizers?

have you tried dual coil cartomizers?

I've heard they don't work with Riva/Ego type batteries with the MOSFET switch.

Is that a myth? Is it hit-or-miss? Are there dual-coil cartos that work with the Riva?

(Bonus question: Are there dual-coil 801 cartos that would work with my Chuck at 6v?)

Though I usually use a syringe for refilling, it isn't necessary. 5ml capacity to last most people all day - isn't purported to damage MOFSET driven batteries - 510 threaded - and for the most part "just works" - MAP tank. It does everything you just described and will run great with your Riva batteries.

Drawbacks: It isn't what I'd call pocket friendly and it can leak if laid down on its side too long. Also, E2's (the guts that go inside it) can sometimes be a little hit and miss. Occasionally I get one that doesn't wick very well, but when I do, I just discard it and put in a different one. A box of E2s can usually be had for around 8 or 9 bucks and I get about 15 to 20 ml of use out of one before cleaning and then another 10 to 15 ml before I discard (other people will clean again.. but they're cheap. I throw them away instead of bothering with a second or third cleaning).

MAP isn't the only tank to look at. There are a couple of others. Stormy's tanks and the GP-SSR are probably just as effective.

I don't know about MOSFET, but my son uses them exclusively on his RIVA. I have a 1100mAh kGo and they rock. They hold 60+ drops and give great TH and flavor. Hope someone can let you know about the MOSFET switch, because they are great and only $2 a piece.

Cool! What kind are you using? Where do you get them?

I use 1.25 ohm from hoosierecigsupply. KBV has 1.5 clear duals that can be taken apart and cleaned. There are also 1.5 black duals out there. Most vendors are getting them (all from SmokTech). They are changing e-cigs for the better. Shop around, and you will find a good deal.

The good thing about the dual coils as far as eGo/Riva batts is concerned is that you're probably never going to short them. The eGo Riva batts are protected by MOFSET instead of a regular protection circuit. If you short an atty or a carto on an eGo or Riva, you've probably killed the MOFSET as well.

The max drain rate on a riva batt is undoubtedly less than the current draw of a 1.6 ohm dual coil, so it's going to be stressing the batt pretty hard.

This thread is worth reading and this thread is an absolute must read if you want to gain a real understanding of how it works.

I have been using the 1.5 dual coil cartomizers on both 750 mah and 1100 mah Riva batteries for about a month now with out a problem. I haven't noticed any battery problems at all. I think the Rivas have less problem with the dual coil it because the Riva's run a higher voltage under load

Hi have you looked at Stormys Tanks and mini tanks, i use the minis and they are very good for me Stormys Vapor Cellar, Electronic Cigarettes & More, have a look

There are three reasons LR stuff isn't recommended for eGo and Riva batts, and the dual coils are a very low risk for one of those three reasons.

As I mentioned before, it's a short that will cause a MOFSET to fail. Something like a 1.5 ohm 510 atty will (likely - there are always exceptions) fail in a shorter amount of time than a 2.4 ohm 510 atty, and one probable cause for failure of something like a 1.5 ohm 510 atty is a short. -- The dual coils can handle a ton of volts and can draw a lot of current without failing, so that type of failure is not a very high risk on the eGo or Riva batts with dual coils.

Another reason they are not recommended is the amount of current they can draw. eGo and Riva batts are not identical as to how much current they can produce (how fast they can discharge), but they are fairly similar. In the first thread I linked to before, there's a post with some numbers on that. The dual coils draw more current than either of those batteries can actually provide, so basically, they run the batts to the max they can produce 100% of the time they are fired. That can be tough on a cheap MOFSET.

The third reason is related to the second, but I can put it in really simple terms: The dual coils (or any other LR atty or carto) empty the batteries faster and therefore the battery will go through more frequent charge cycles. That just plain wears them out... but over a fairly long period of time since they are rated for something around 250 or more charge cycles.

I have been using a 1100mAh exclusively with 1.25 ohm cartos. My son has used nothing but 1.5 ohm on his RIVA. They have worked great.

Battery life is not bad at all. My 1100 mAh lasts at least all day (charge each night). The RIVA lasts the 19 yr old at least 9 hours. Either way, that is way better than you make it out to be. When you say that LR "empty the batteries faster and therefore the battery will go through more frequent charge cycles. That just plain wears them out," I think you may be stretching. I would charge my kGo each night anyway. The boy carries both batteries with different juice, and charges both every night (which he would anyway).

Now I don't actually know the long term effects LR will play on our batteries. I do know that a RIVA is only $30, and my 1100mAh kGo was $40. The flavor, TH and vapor that comes from a dual coil is so much better than standard. I would buy a new kit every year if that was the cost. These duals outlast other LR cartos because they burn cooler. I have been running one for 3 weeks now. Not even close to worrying about burning it. When it dies, it will be from finally clogging.

Also the RIVA runs at about 3.7v. That appears to be perfect for these dual coils. My kGo is about 4+ volts at full charge. It steams the 1.25 ohm duals I use on it. OP wanted something he could use driving curvy roads, something he could vape for extended period of time w/o hassle. I say carry around two dual coil cartomizers with your favorite two juices. Maybe some Black Cherry from VaporGod in one, and some Clint Vapewood from Joogler Juice in the other. And happy vaping.

Thanks for all the advice, guys! I ordered a couple of the dual-coil cartos and I'm thinking about trying a Storm tank. We'll see what happens. As has been pointed out, none of this stuff is hugely expensive, so if something breaks, no big deal.

I've been using the 1.5 Dual Coils on Riva 750 mah-Ego 650-Ego 900 mah-KGo 1100 mah for about two weeks with no ill effects.
Actually I prefer the 2.0 Ohm on the KGo.

Update: I ordered some 1.25 cartos and an Echo-E, and I love the 1.25 cartos while the Echo-E is OK as well (I had to pop out the inner ring to get it to fit over the threads on my Riva batt). Only disadvantage is that the cone is so snug that it scrapes off the surface of the cartos, so unless I want it to look terrible I have to be careful how I fit the cone over it (I keep them together, and avoid moving the cone back up on the carto to avoid unsightly scrapes).

The cartos seem to last a couple weeks before getting kind of grungy (haven't tried cleaning them, but I'm saving them), so if it costs me $1 a week for them, it's a good deal. Thanks to everyone for all the advice!
