Lavatube voltage stabiity with battery usage?

[MASTER0FDAMPF]

I have only noticed significant drops when the battery hits about 3.2v. I know...I know...bad kid...don't drain the battery that much! I just don't check every 5 mins to see where the battery is at. I change out when the voltage drops. I always let the batteries "normalize" for about 20 minutes to an hour before putting them on the charger.

just so you are aware, letting the battery "normalize" won't really do much in the way of letting the voltage go up. the voltage on a battery under load will be a bit lower than it's unloaded voltage, more so when the battery is getting close to dead, but the load it takes to display the battery voltage on your unit is barely more than nil, and as such, the fully unloaded (as in out of the unit completely) will be ABOUT the same as the voltage that is has on it while it is in the unit displaying the voltage (but, obviously, without the unit being activated and heating the coil(s)). by the time you take the battery out of the unit and plug in the charger, the battery voltage will have normalized to within 99% of what it will stabilize at, and after more than 5-10 minutes, you are guaranteed to have the battery voltage only go down from there.... of course with lithium based batteries, you don't get a whole lot of self-discharge, so the voltage won't drop appreciably in the 20-60 minutes you might let it normalize, but it also won't rise. just a thought.... you really are better off not letting it go down that low, as there is no real way (not on a normal consumer grade charging unit, anyways) to lessen the load on the charger when the battery is that low... high end chargers can gradually increase their output but they are a whole different ballpark

also, one of the dangers in letting them get that low is simply permenant damage done to the battery when the voltage drops too much.... letting the battery sit around can't fix or help that at all... and that damage is quite often what causes these batteries to have "problems" (read: explode violently) when they are charged again from such low levels...

I have started checking them about every 1/8th inch of tank. Usually swapping them out around 3.5. It just sucks that that means you only get a few good hours off a batter (5 or 6) but oh well...still better vaping and certainly less charging than a 510

If it only varies .1-.3 I should be ok if it runs .4-.6 not so much, I am under 5V and over 2.6ohms I usually run a 3.0ohm at 4V on a Provari so I am thinking of picking one up as beater/backup for the Provari. I can get a tube only for $32 or a kit for $48 thinking tube only and useing the AW IMRs that I already have and not worry about the end cap not screwing completly.

I don't notice much dropoff at all, but then again I haven't let the batt get below 3.7V.. I have no way to measure it precisely, but I'm pretty sure I'd notice a .4-.6 drop. Maybe that was a dud unit or the battery wasn't up to snuff? I've never heard anyone else having such a big drop.

Vaping my 2.5ohm carto at 5.5v I notice a drop off around 3.7-3.8v (have to take longer drags for less vapor). I notice this with the 1600 knock off and the AW 2000 and always swap batteries around this time. Currently charging the Panasonic CGR18650CH to see how this thing will work out on the LT. It fits perfectly unlike the AW 2000 though which I'm loving.

Do the AW IMR 2000 fit and work in the LT?

Yes they do but on mine it leaves a little gap at the threads... I would suggest that Panasonic battery for the
LT though, I feel like I'm getting much better performance than my Aw 2000 and it doesn't leave a gap. Perhaps this battery is the Aw slayer that another thread was calling it.

These are the measurements I recorded when testing the Lavatube.

Cartomizer Ohms	Battery Voltage	Voltage Setting	Voltage Recorded	Voltage Difference
3.2	4.2	6.0	6.0	0
3.2	4.0	6.0	5.8	-0.2
3.2	3.5	6.0	5.4	-0.6
3.2	3.3	6.0	5.1	-0.9
3.2	3.2	6.0	4.9	-1.1

Thanks I have the AW2000s for a Provari and was thinking of one of these as a backup/beater.
