Yes, it's 2.5 and as others have said it's closer to 2.3-2.4 if it's a true V1 (flat top cap). There's also the V1.5 (still flat top) and V1.5T (angled top cap), the V1.5 claims a higher amp limit but there were some major issues with it, see 9 posts down here: http://www.e-cigarette-forum.com/for...thread-58.html
The 1.5T has an angled top cap and claims to be capable of 4 amps (I have one of these) but in real world conditions it is realistically closer to 3.6-3.7.
The reason that you are using less juice is because with your low ohm coils it's going into safety all the time. You are probably running around 3.5V no matter what the screen is telling you, they HATE low ohm coils. That is one BIG flaw with the LT is that it doesn't actually display what voltage it's running at, just what you set it at, and if that's above the what it can safely run at those ohms then it self adjusts to compensate.
Clear as mud????
This is an old thread...My Lavatube is still holding up. I was trying to google the low ohm limit of the first Lavatube and I actually ran across my own thread.
Does anybody know if the V1 Lavatube has a low ohm limit?
I know the V1 Lavatube doesn't put out much power. Using an RBA, I wouldn't recommend using 28g wire. I mean it works with 28g, but I have to take 2 or 3 prime puffs to get one good puff. 30g wire in an RBA on the v1 Lavatube works OK for good throat hit. It works pretty well with 32g.
I'm using 32g now and the throat hit is unsatisfying. I'm going to re-build with 30g and hope for the best. I don't know the ohms, since the Lavatube doesn't give that information. I could use a multimeter, but I'm too lazy to do that. Based on the many builds I've done, I'm guessing this 32g build is around 2 ohms. I just don't know, or forgot how low of ohms I can go on a V1 Lavatube.
