Your riva starts at 3.7V on a full charge and slowly drops as the battery drains.
LR is generally considered 2.0ohm and below. Low resistance cartos produce a warmer vape with more TH. The lower the ohm, the warmer the vape will be. So while a 1.5ohm and 2.0ohm carto are both considered LR, the 1.5ohm will produce warmer vapor than the 2.0ohm.
Standard resistance is generally about 2.5ohm-3.0ohm. SR cartos will produce a cooler vape. The 2.7ohm cartos will work fine on your Riva, but it will be a cooler vape and won't have as much of a "kick" compared to the LR cartos you use.
Most people prefer LR cartos over SR, and LRs were made to simulate higher voltage vaping.
The Smoktech tanks do work well and they are cheap which is nice. If yOur going to get one though, I would get just the regular Smoktech tank and not the eGo tank that you posted a link to. Their basically the same thing, but the eGo one is fairly new and has a different base. Basically the eGo one was made so you'll have a streamlined look when it's used on an eGo. Problem is though, the eGo one will only fit on a device that has eGo threading. So if you ever get another PV that doesn't have eGo threading, that tank won't fit unless you use an eGo adapter. Also the eGo tanks don't use the same flanged cartos that the regular 3.5ml and 6ml Smoktech tanks use. So if you want pre-punched cartos, youll have to get the pre-punched cartos for the eGo tank, and as far as I know, not many vendors have them. Madvapes is the only vendor I know that has the eGo Smoktech tanks and the eGo Smoktech pre-punched cartos.
The regular Smoktech tanks work great and can be used on any device that has 510 threading. I have a few of the 3.5ml tanks that I use on my EGo-twist and I also have one of the newer 4.5ml tanks that I use on my SS mini v-tube and I really like them.
For the regular Smoktech tanks there is a variety of different ohm pre-punched cartos you could use, or you can just use any XL cartos and punch them yourself. The XL Boge cartos fit in the Smoktech tanks fine, but you just have to punch the hole Reply . Reply With Quote . . Blog this Post . .. .yourself. Also a lot of vendors carry the regular Smoktech tanks and the pre-punched replacement cartos, so you'd have your choice of where to buy them from, unlike if you got the eGo Smoktech tanks since so few vendors carry them.
Like mentioned above, they do come with a 1.5ohm dual coil pre-punched carto, which really don't work very well on lower voltage devices like an eGo/riva. You can buy single coil pre-punched cartos though is a variety of different ohms that will work a lot better on your Riva.
If I were you I would get a regular 3.5ml Smoktech tank and then also buy some of the 1.7ohm single coil pre-punched cartos. The 3.5ml tanks look very nice on eGo/riva sized PVs, and the 1.7ohm cartos work great and are very popular.
Crystal Clear Vaping sells the 1.7ohm single coil pre-punched cartos (also called the Ressurectors) for a good price and they have free shipping. Many other vendors sell the Smoktech tanks and the pre-punched cartos for them so you can get them from wherever you like.
And if you want to have a streamlined look with the regular Smoktech tank, you can get a 3.5ml DCT cone for a few bucks and that will basically give you the same look as the eGo Smoktech tank would
