Lava Tube voltage tests w/ Dua Coils and others.

[mjradik]

So I got my lava tube clone (Apallo VTube) in today. So I decided to do some tests.

All tests using new or almost new attys/cartos. I notice on the lava tube, using a old/worn atty/carto the max voltage drops off significantly. For lava tube, with the exception of the 'no load' test, its set at 6v. The theory max below is what that atty/carto should be able to do according to the mathmatical equation and this chart. https://docs.google.com/spreadsheet/ccc?key=0AlZnGjZRjO_UdGo3VVlnVHY0VExZLVd5aDkwUEJEZXc#gid=1
dc=dual coil carto. Voltages are 'first hit' voltages.. not a long drag.

Theory Max ...../ ego batt ...... / lava tube
no load ..... N/A ..... 3.76-3.8 ..... 2.93-6.2
1.6 dc ..... 4.0 ..... 3.42-3.45 ..... 3.59-3.66
1.7 res ..... 4 3 ..... 3.47-3.49 ..... 3.99-4.18
emdcc ..... 4.0 ..... 3.47-3.49 ..... 4.09-4.21
2.5 dc ..... 6.0 ..... 3.54-3.57 ..... 4.6-4.9
3.0 atty ..... 7.4+ ..... 3.57-3.59 ..... 5.4-5.6
SR ego-t atty .. ??? ..... 3.53-3.55 ..... 4.6-4.7

If you adjust the lava tube to just below the max limit of the device, voltages are more consistent through out the vape. The longer drag you take, or the hotter the atty/cartos gets, the more the voltage drops off. (well below what I listed above)

With the exception of the emdcc and the resurrector, I think the lava tube is 'too carefull'.. meaing it drops the voltages even if it might not have to. Thats one thing I don't like about it. Its says the amp limit is 2.5, but I think its closer to 2.0. Because a 2.5 ohm catro should go to 6 volts, but the lava tube won't let it even get to 5. That sux... In short the lava tube is an OK VV device... If I was a 'pro' vaper, I wouldn't like it at all.

I don't think the emdcc is truly 1.6 ohm, because the lavatube can rock it at 4.2 volts, and a 1.6 ohm device shouldn't be able to go above 4.0 volts.

I notice the 2.5, 3.0 and SR ego-T atty get real hot real quick when vaping at it max limit. yes the vape is warm, but man, it almost burnt me when I touched it. Thats a turn off for me.

The 2.5 DC I was using was from mad vapes. Was not impressed with it even at 4.9 volts.

In short after vaping all day, the emdcc and resurrector at 4.1 volts BLOW THE SOCKs OFF the 2.5 and 3.0 device at higher voltages. I get a more satifying vape rocking the 1.7 resurrector at 4.1 volts, than the 2.5 dc at 4.9 volts. Maybe its the carto, i dunno. And there is a huge difference between the resurrector on the ego at 3.49 volts, and on the lava tube at 4.1 volts. The emdcc at 4.1 is almost just as good.

I think I'm going to stick with the resurrector in a tank mod setup and the emdcc for now at 4.1 volts..

yea.. I've figured out that you have to "sneak up" on the voltage. I figured I could just set it at 6v and the LT would keep me at the 2.5 ceiling.. but it drops it way below that. I have to kinda work my way up to get the max voltage. I can't imagine not having a voltmeter to be able to actually see what is going on. I know some people don't care, as long as they get a good vape and that's fine. But I consider myself a "pro vaper" and I do want to know what is going on and what voltage I am vaping.

If the dang thing wasn't so pretty to look at.. and light.. and easy to adjust. I kinda like it sitting here on my desk. And I can get a good vape with the right setting and hardware. I'm not a mod collector and I'm not a seller either. I also don't like duplicate devices. My devices each have their place. I'd kinda like to have a buzz pro or an Ipro, but that would be redundant since I have a provari.. kinda would like a vv reo, but since I have a kick .... vv bottom feeder I won't get that either. My madvapes vv box is small and easy to cut on and off, and works like it is supposed to (even with dual coils). The LT is the only one that doesn't have a "niche" so to speak. I've gone to the classys several times to sell it but never do. Even though it doesn't do exactly what it is supposed to do, I still like it

 

[mjradik]

uh.. oh... I'm noticing something with the lava tube that SUX... My tests above were done with a freshly charged lava tube. I notice with a lava tube battery about half charged or nearing to run out, the voltages on some of the items drop waaaaaay of. Right now I have 3.6v remaining life of the battery. The 1.7 resurrector and EMDCC are only vaping at 3.6 volts. The 1.6 DC is vaping at 3.1 volts...

 

[prateus]

....ty buzz man. i found that the dual coil 2.5s weren't great at 5-6v either. The 1.8 ohm hit nice and showed 4.4-4.56 v output on my friends meter at 4.5-5. I can't remember if I checked it at anything higher but the battery underload maxed out. I replied to you in my original thread. Maybe since you have a meter all the time you could check out my findings.

hit power 7 times(mine does it at 5 wierd) that will be unloaded IMR battery voltage before it goes through boost circuit. Hold fire button, then press power button once more, the voltage shown will be IMR battery underload as it goes into the boost circuit. people have wide variations with this device. I always try to twitch batts at 3.6 Still I only paid CND 65$ for the device with two batts/2atties/case and a nice charger and it beats buying 2 ego pts anyday. Also with a one year warranty, I am happy. They are releasing a new revision in the summer. The Lavatube 2 lol. It will have ohm checking and is supposed to have a 3 amp limit, oh and it will be both a mini and reg in one. It will come with a reg cap for 18350 and an extension for 18650. That is all I know now.

Also Lavatube Clones are hitting the market and I don't consider appolo canvape ect to be clones. They are unbranded L-rider devices. Vision the company that makes the vision deux clearomizers and the big clearomizer grande tanks has released their own lavatube. They still call it a lava tube which is dumb imo.

The Lt is the Next Ego.
Maybe the clones will be better, I hope so, although I love my LT.

Next year there will be some good choices for chinese vv's.

I'm new to vaping and after a week of researching this site, I have decided to purchase my first e-cg.
The LT looks to be exactly what I'm looking for.
The way I see it, it looks like it auto adjust to keep you in the green areas in the charts below.
It seems it has a 2.5 watt protection, which I think is the same as the provari maybe?
As long as the Volts/Resistance is < or = to 2.5 you're good and if you go over that, it auto adjust the volts.
Whatcha think?



Sorry, images seem a little small, but I found them on the forum.
There are links to larger ones.

I think the LT plays it toooo safe... It says its a 2.5 amp limit, but based on my experience it seems to be around 2.0-2.2 amp limit. I should be able to vape my 2.5 ohm at 6 volts (2.5 amps) but the LT maxes that out at 4.9v.. arrggg. Yes the Lt is great of the beginner, and do reccoment it for you skelley, but for me peronally, I want more control, and don't want some auto correcting me to much.. So I might be abandoning my Lt..

 

[skelley]

Yeah, that doesn't sound good for sure. Now I got my eye on the Buzz Pro, no limiting.....lol.

 

[mjradik]

ofcourse I want to throw in my disclaimer. I honestly don't know if I have a defective unit or not. I'm just posting my experiences of my LT. If my unit is bad, then I'm throwing out misleading information and don't want to discourage anyone from getting the LT. If someone posts thier thier LT is reaching the 2.5-2.6 amp limit, then great... I want one of those.. hahaha.

 

[prateus]

It seems LT's range with safety from 2-2.7 amps.

Mjradik, When did you get your Lt and is the power buttons red plastic with black plastic buttons? It seems diff rev have diff safetys.

got it 5 days ago... yes black up/down buttons, red power button. I do see on some other threads, people report getting a 10 watt limit. Wattage is different from amps, and doesn't go to a 1 to 1 scale with samps, but thats what I'm seeing. 4.9v at 2.5 ohm, and 5.6v at 3.0 ohm are both 10 watts.

 

[Butters78]

The LT is my entry into VV.. Something fun to tinker with. I'm going to save up for a provari eventually. The LT will be for getting my feet wet. See how I like VV. The results are somewhat disheartening but what do you expect for 60 bucks?

this by far is the best review i seen so far...

 

[Butters78]

It should have a feature to turn off the auto protect if you really want to..

4.9v at 2.5 ohm is 9.6 watts and
5.6v at 3.0 ohm is 10.4 watts

 

[prateus]

Also I don't agree with the 10 amp limit because a DC 1.5 is 10 watts at 3.87 but around 2.57 watts, and yes lots of people are getting 3.8 out of a 1.5ohm but other report as low as 3.2 which is 6.18 watts so I do not beleive the 10 watt. I wish someone with a meter would do something like Phil did, aka pbusardo.

 

[Karla Lyle]

I don't have a meter either but have noticed the 2.5 DCC aren't very good on the LT and I bought them thinking they would be perfect. Has anyone tried the 2 ohm DCC? I know theoretically you'd only be able to go to 5 v but it may vape better? I'm just sticking with my Boge 3ohm til I find something better.

 

[mjradik]

Honestly.. I'm thinking about returning my LT, and just getting a stright 3.7v tube mod, and using it with my 1.7ohm resurrectors.. Thats a much better vape than 2.5ohm on the LT. The LT only lets you get about 5v on 2.5ohm You need 6v to get a good vape on 2.5ohm...

using 1.7ohm resurrectors on a fresh 4.2v battery ROCKS!!! Even down to 3.6v, it rocks...

 

[Butters78]

I still haven't tried my ressurectors on the LT. You just reminded me I needed to ha.

 

[Butters78]

I decided to keep the LT as a back up and I went ahead and ordered the Provari V2.. my wallet still hurts but I feel the Provari is everything I'm looking for.
