Lavatube voltage stabiity with battery usage?

[mikeinbc]

I'm wondering if the Lavatube's voltage remains stable as the battery is used up? For example, does the voltage output REMAIN at a setting of 4.5 volts as the AR IMR 18650 battery drains? I know all about the "voltage adjustment" for LR and dual coil cartos/attys. I am just looking for a STABLE VV mod with regular attys/cartos.

I have the VaperZone VV (lavatube without the lavatube logo) and I brought the battery pretty low. The tube is going to flux with a new battery or a drained battery. This isnt expert handcrafted stuff, its a reasonably priced Chinese VV tube mod. To be pumped out to the masses for a descent VV vape. I have seen my voltages flux .1-.3 in either direction - even with a full battery. This is with a 510 voltage meter attached. I really dont notice the difference in the vape, but im sure someone will say they do. If you want exacting standards I would look more to the higher end, the provari comes to mind.

Joe - does this become worse as the battery looses charge ?

Thanks Joe. That's good enough for me. Anything is better than my ego. I can handle a slight drop in voltage, but dropping over a cliff...forget it.

I have the mini lava tube and I really started using it hard this weekend and it really doesn't hold the voltage like a provari, but I will say it will have a better chance if you don't order the kit and get you some AW batteries and a charger elsewhere.

I think my problems are from the cheap 18650 batteries that came with mine, and the fact that they aren't 18650, the mini uses 18350, so that doesn't really help.

So that said with my current set up is doesn't hold the voltage all the way thru to a dead battery like the provari, but it is 3000 times better than any ego, and for the money does the job.

Yes it will begin to drop off, but not something I really notice on my vape. It will drop a few .1's as the battery drains down. I dont think i ever killed my battery to truly see what happens on a 1/4 batter life.

May I suggest the vaperzone model its about 20 bucks cheaper. Your getting the same exact thing. Also, the lavatube style mods dont like most 18650 batteries with nipples on them - the bottom will not close all the way.

Maybe increasing the voltage slightly over time would take care of this problem.

Thanks for the suggestion Joe, but I'm from Canada and I was planning on ordering on this side of the border. You're familiar with Canada: The land of cold winters, beautful scenery, and nic liquid confiscation.

How does that work up there. Do they have some type of testing kit to see if your liquid has nicotine. Not saying you do this, hehehe.. but is it still possible to get nic liquid overseas?

If we order nic juice from the US or China, there's a chance that it would be confiscated especially if it's listed as "nicotine liquid". Direct testing for nicotine is rare because of the procedures involved. I don't think there's a quick testing kit yet, but I'm sure someone's working on it. The government has to stop those renegade vapers taking away the big tax dollars.

I want my vv devices to stay at a consistant and reliable voltage. The LT drops it's voltage as the batt discharges, the led readout will still read the voltage you set, but a voltmeter tells the true tale. With mine, it didn't matter what batt I used, Aw brand or not, the voltage dropped. I didn't like that at all. I could tell the vape wasn't the same. I quit using egos and 3.7 box mods for this reason.

Some people don't know or care what voltage they are vaping at as long as they get a good vape. That's fine. But I want to know.

I have done significant metering at various levels of the charge of the battery under load and have found that unless you vape over 5v you are pretty safe on the voltage as long as you are using 2.6 ohm or higher stuff. My LT under load 2.8 metered carto got me 5.9 v under load until about 3.9v charge then it dips to 5.6v max at 3.6v on the battery it drops again to 5.3v max final drop being to 4.9 max v at the 3.4 mark.

Not an issue to me since I tend to vape at 4.8-5.2 depending on mood...

YMMV may vary as much as the next guys... It seems the voltage out put is a bit inconsistent from tube to tube...

I dont know how your law is worded but they starting to get nicotine from eggplants. It actually has a lot in it. The FDA here rules over Tobacco, so if anything goes south in USA we will just get our nic from Eggplants.

Instability on lower battery voltages shouldn't be that big an issue, since we are told not to let our Li-ion batteries run to cutoff. The higher currents during charging a severely discharged battery lead to greater heat and more risk of explosion. Frequent charging is recommended, anyway.

I don't have one, but the Lavatube looks like a good deal at half the price of a Provari. I know it's not as durable, but it looks like a good entry into vv tube mod vaping.

Thanks donnah, Scotay87, Joe, and DaveP. I'm going to get the Lavatube and have some fun playing with the voltages. DaveP- Good reminder about the importance of recharging before full discharge.

Thats exactly why I got the lavatube style mod. Until you really understand voltage and ohms you should get a mod with some sort of protection built in, so your not blowing up your coils. Now that I really understand it, its still my main vape mod.

It will fluctuate by ~-.1-.3, but not necessarily enough to ruin the vape.

The quality of a vape isn't in the numbers, it's in the puff itself. I haven't noticed vapor falloff TOO much on a low battery, but as usual, a fresh battery still gives you that extra "kick". To compensate, I usually just dial it up a little higher during the day. I use a 2.5ohm 306 atomizer, debridged and dewicked. I have yet to be disappointed with it.

I have the silver LT from Volcano with the authentic AW battery.

Before ordering though, the Trustfire charger that came with mine already started to fray on the connector cable. Volcano wants me to send it back and THEN they'll replace it. That's like a week without a vape. All my other batteries are dead and/or lost

That's not good I'm thinking of getting at least 4 AW batteries if the 2000mah ever get back in stock.

When I had my LavaTube, I noticed a .4 ~ .6v drop north of 5v when the battery was 3.8v or lower, with the AW IMR 1600mAh and also the 2000mAh batteries, not the fakes, or other brands. It annoyed me, but only because I'm fairly particular and I wanted what I set it to, not what it was capable of pushing. This was confirmed with a 510 Volt Meter under load on the 3ohm atomizer that was included with the kit.

While it may be ok for others, it wasn't for me, and is precisely the reason I purchased the ProVari.

While I agree, it's perfect to get you into the VV arena with a decent price (especially Apollo's LavaTube, $59 is a steal) and it works wonders in getting people off analogs, it just wouldn't cut it for me. As with everything in the e-cigs industry, it's all about personal preference.
