Do you prefer a LR or SR carto?

[rock_lobsterrr]

Since owning my ProVari I've only used a SR with a tank. Love, love, LOVE varying my voltage around throughout the day. Prior to my ProVari I was only using LR cartos on my eGo battery. Tonight was the first time I slapped a LR carto on my ProVari and notice I don't have as much range. When I say "don't have as much range" I mean it hits my throat harder and at times tastes burnt at a higher voltage... a voltage where I'm getting great vapes from a SR carto.

Is this how it's suppose to be? Are LR cartos geared more for a lower voltage battery such as an ego?

Just curious what the ProVari community prefers. Right now I'm thinking I'm about purchasing only SR cartos from here on out...

For me it's just the Boge 3.0 cartos in my tanks.

I like where your head is at! Pretty sure that's the route I'm taking. Just bought a saddle valve at Home Depot today. Just need to stock up on tanks. Would like about 5 for my top flavors.

The Boge SR 3.0 will carry you all the way across the voltage board on the Provari. The LRs have a slight bit of play in the lower voltage range, but you'll get more out of the SRs.

Also... I get lots more batt life with the 3ohm cartos than I did with the lower 1.7 resurrectors. The new xxl boge 3ohm cartos are awesome in a tank!

I've been using Boge SR on my black Provari, and Smoktech LR dual coils on my satin silver one for a while now.

Both use tanks, I do find that the Boge tend to last longer, but that's probably the juice. Better flavor too when using the same juice in both.

WHen my supply of LR run out I probably won't get any more.

This makes sense once you learn about the basic principles of Ohm's law, which you really don't need an EE degree to understand. Think of your heating element (the coil) like you would a light bulb, and then equate wattage with heat and you begin to see how it works. The higher the wattage, the more heat generated by the coil, which can lead to harsher hits and burnt taste.

Voltage (E) = Current (I) * Resistance (R)
Power (watts) = Voltage (E) * Current (I)

LR 1.5 ohms @ 6v = 24 watts
LR/SR 2 ohms @ 6v = 18 watts
SR 2.5 ohms @ 6v = 14.4 watts
SR 3 ohms @ 6v = 12 watts
and so on...

Here's a link to an online calculator in which you can input the carto ohms (resistance) and batter voltage and it will calculate the amps and wattage for you. If you have a smart phone, you can probably find an Ohm's law calculator in the app market if you want one.
Ohm's Law Calculator

Also keep in mind that voltage / resistance / wattage are relative to the design of a particular device as well. For instance, I was using LR eGo-C atties @ 1.7 ohms on a regulated 3.3v battery (6.4 watts), but I'm finding I get better performance from a Stardust clearomizer on the same battery @ 2.1 to 2.4 ohms (4.5 to 5 watts). However, all other things being equal, you should be able to find that sweet spot in the wattage for the device / juice combination you're using with a bit of trial and error.

What donnah said is correct....In my experience, LR Dual coil cartos are nothing more than a BATTERY KILLER on the Provari......I now use 3.0 ohm cartos on my Provari with Excellent results........

 

[hairball]

3ohm Boge for me.

 

[katann23]

SR cartos for me as well.

 

[NeonPriest]

i have only had my provari mini for 2 days but i have tried a LR carto and i really don't see the need for it, maybe someone can fill me in? i use standard 3ohm boge cartomizers as well and adjust the voltage to exactly what i like.

 

[The Lukester]

SR is the only way to go IMO on any Variable voltage device. Why bother yourself with the error codes lol. If you have 3.7 devices that you still use then yes LR cartos are nice to have around but why use them when you have the Provari which can provide you with a much more enjoyable vape!

 

[rock_lobsterrr]

Awesome. I'm glad I asked this question. Thanks for all the feedback. I feel a sense of relief knowing a lot of the community feels the same way.

I decided to put all my LR Boge cartos up for trade over in the classifieds section since I don't feel the need to use them anymore. I have a bunch of Stardusts that I use on my eGo battery when I'm going places that my ProVari can't =)

Thanks again everybody!

While I'm glad you got the information you were seeking, I wouldn't sell them. Just vape them if they're standard LR Boge cartos. They work fine on the Provari at lower voltages. I use 2 ohm and 3 ohm interchangeably, because sometimes one or the other is out of stock. Not a big deal (although your battery will last a bit longer with SR).

 

[rock_lobsterrr]

Good point. I may just keep them. I also have a friend who is just leaning the ropes. They would make a great donation to a newbie!

Good catch Frick....Why waste them?

 

[WA3PNT]

I want to try the Boge, but I'm a bit confused over the XL and XXL types that are mentioned.

I have a 7ML LavaTank, a 3.5ML LavaTank, a Sub Tank and a Who's Your Daddy tank on the way.

I've been using the 1.7 Ohm Dual Coil and 3.0 Ohm Single Coil pre-punched SmokeTech Cartomizers.

I have a Cartomizer Punch on hand to punch the Boge Cartomizers, if I could only figure out which ones to purchase.

Can someone please post a link where I can obtain the Boge XXL Cartomizers? I'm not concerned if they protrude up past the top of the Tanks that I have.

Thanks for any help.

If what I'm using will only be used on my ProVari - 3ohm Boges at 5v for my M1A1 Buzz Tank.
If what I'm using will be shared between my ProVari & KGO - 2ohm Boges and attys do it for me at 3.7v

 

[ebbrey]

I dont understand this, i know i asked in another thread in the carto forum earlier and got the msg LR use lesser battery as you vape on lower voltage.

I like around 10 watts when i vape and my current LR boge 2.0 shows a resistance of 2.2, so i have it set up on 4.7 volts which should be about 10 watts.

If i had a 3.0 boge with lets say a resistance of 3 vaping on 4.7 vols would only be 7 watts, meaning i would need to crank the provari up to 5.5 volts to get the same watts.

How can this extend battery life? Im not an electrical engineer but it sounds cheaper on the battery to vape on 4.7 than 5.5.

Any explenation appreciated

 

[Frick]

This might get complicated.

In your examples:

4.7V * 4.7V / 2.2 ohms = 10.04 watts.

Amperage draw would be 2.21 amps on a mechanical mod (no boost circuit).

5.5V * 5.5V / 3 ohms = 10.08 watts

Amperage draw = 1.83 amps, again on a strictly mechanical mod (disregarding the fact that we don't have 5.5V batteries).

The higher-resistance coil draws less amperage to provide the same wattage at the coil. We should get significantly better battery life using a higher-resistance coil, all else being equal.

BUT, the boost circuit changes all that, because the unit is drawing additional amperage from the battery to reach the set voltage.

So, we have to substitute the battery voltage to amperage calculations, not the set voltage.

Except we can't really do that, because battery voltage is variable from 4.2V right off the charger, to ~3.4 or 3.3V at cutoff, and the boost circuit isn't 100% efficient.

If we use a "happy average" of 3.7V in the calculations, we get:

2.2 ohm coil at 4.7V set voltage will draw 2.71 amps, but we have to factor in boost circuit efficiency. Provape uses a figure of 90-95% efficient, so if we assume 90%, we're drawing 2.71 amps/0.9 = 3.01 amps.

2.2 ohm coil, 4.7 set voltage, 3.01 amp draw.

Second example: 3 ohm coil at 5.5V set voltage will draw 2.71 amps again; after factored for efficiency, 3.01 amps.

So doing the math gives us the same result, regardless of coil resistance.

Despite that fact, with all the math done and considerations taken, I still get better battery life out of a 3 ohm coil than I do a 2 ohm. I can't be sure why, because according to the math, it's impossible, but after owning a Provari for a few months and running a wide variety of coils, it seems it's true.
