IMR a cheap as chips. Really. After you buy US$300 li-po packs that can burst / get punctured after 3 charges (happened more than once at my field) , IMR are a no brainer especially when the goal is to keep off the analogs

I finally got a real dripper, a Tobeco Rogue clone. Put in two 2.6ohm 30ga coils for 1.3. Got it working well at 8-12 watts. Kept going up in watts all the way to 15. Then I looked at the screen, hit the button and it showed 13.5. Took another hit and it showed 12.9. Why?
Check your coil screws. Sometimes one or both may loosen a bit during wicking causing the ohms to jump. Make sure both are nice and tight. That should do it.
V5? The v5 will read actual output. A low or weak battery will not sustain 15w once its below 3.7.. That's why I stack 18350 and I can push it to 6v 24w... 15w will always be there when stacked.
Thanks for the replies.
Before this happened I pulled out the 18490 and put in a full charged AW 18650 2000mah.
I poked and pushed and now it says low load so I think I need to start over.
Did I hit the amp limit or something? I didn't think 1.3 ohms was that low.

V3/5 will be restricted with a single battery you will only get 15w through out the battery charge if you have a 2.3-2.4 ohm load period. .. End of story.
like you may get 15w for a couple pulls at 1.3 till the battery starts to drop.
Time to stack it up I recommend the new AWT 18350 over efest. From imrbatteries.com best price 11.00 a pair shipped. I've only had them a short time but like them so far their test ratings are higher than all the others.
Oh and yeah 1.3 is the limit.. You probably made it go under. Move the coils or force fire to see if it clears up.

I've been running 1.3 stacked 18350 for the last year. The power difference is night and day... You just upgraded it to a 24w device instead of 15
I tested it with a single 2.6 so didn't run into the limit then. Worked fine at whatever it was putting out until I started upping the watts.
It still shows 1.3 on my MVP but it is a 5v or 11w limit. I think the MVP tends to round up.

The other factor would be weak/old battery or poor b-/ thread contacts reducing the amp capabilities coming from the battery.
That should cover the potential issues

Something to think about in the future but for now the battery is fairly new and I cleaned everything. It is probably just hovering around the 1.2-1.3 range depending on temperature. Mostly I wanted to see how high I could go because I have never had any topper that could go over 11 watts.
The lower readout of power compared to ypur setting is directly related to the battery configuration holding you back.
Its way more than worth it to stack in the zmax.
Going below 1.3 won't affect power readout only produce low load reading and prevent from firing.

Previous build was 10 wraps on 5/64 drill which showed 2.6 each for 1.3 dual. This time I went 11 wraps, still shows 1.3 but now firing at 13 watts for a couple then 12.3 after some heat. Oh well, as long as it works.
Ok I think I get it now. As the battery voltage drops, the ability to put out the selected watts drops. It was down to 10.5 watts so I checked the battery, it was 3.6v. Put in a new battery and now it is back to 13w.
I thought the circuitry would boost the power as the battery drains.

Haha, complex question. To an extent yes but you must be ohmed up so battery and chip is capable of amp load your asking for.
The sigelie will maintain constant voltage/ wattage through most the charge with one battery (input voltage of 4.2-3.2) if you are at 2.4 ohms or above for the sigelie.
Since I want that consistency running below 2 I use the stacked setup because I have an input voltage of 8.2-6.4 so I always have more than 6v available to deliver to the coil. 2 more volts run time and a lower amp load on the batteries. Making the setup last a long long time at high wattages..
I think all mods will produce lower power as the battery drains unless you are in the median range of the device. Where with a low 3.3v input it can be converted to desired wattage or the maximum wattage... I don't think a DNA 30/40, or any other higher wattage mods running single batteries; will be able to put out thier rated maximum output when the battery is below a 3.7v input.
The benefit of stacking batteries is that you have an input of 8.4v of power.
Sigelie took notice and their 100w is a stacked/series setup.

I didn't buy the Zmax for low ohm vaping but I thought the idea of having VV and VW was to get more out of the battery than it can provide mechanically by means of boost or the opposite with buck.
I got to around 160 puffs on the 18650 and it dropped to 10+watts. Switched to a fresh 18490. Started out getting 13w. Now at 50 puffs the battery is down to 3.9 and the actual watts is 11.7. Using the Steam Engine that is the same as ohms law. So I have a mech?
ETA I reread your last post about staying in the median range. I guess I am puzzled at what other people are doing with subohm and 20-50w boxes. Switching batteries every 50-100 puffs?

Jeremy is correct. Since the device has a greater voltage to work with when stacked, the Sigelei can maintain a constant output much more effectively than if you are in a single battery config. The Sigelei maintains a constant output by increasing the "duty cycle" of the square wave as the battery voltage drops (the square wave is made HIGH for longer periods of time than it is LOW). In other words, it's not the battery voltage that is boosted, but rather the amount of "time" in the square wave that the voltage is applied to the atomizer. As the battery voltage continues to sag, the duty cycle will eventually max out at 100% as the device attempts to maintain the output power you've set. Once that happens, the device can no longer increase the duty cycle to compensate for battery sag since it's maxed at HIGH for the full period of the square wave. You can see when you've reached that point on the V5 by noting the reduced output power displayed on the screen.
I don't vape at high power or use low ohm coils, so a single 18650 battery last a full day (or more) at around 8 watts and 2.5 ohms. Those that prefer to vape at high power levels and/or down around 1.3 ohms will get better performance when using stacked 18350's.

I normally run a single 2 ohm coil and the V5 is fine for that. Just disappointed that I couldn't run 13-15w for any length of time with what I thought was a modest dual coil setup.
I can always pull one coil and run 2.6 or recoil it to a single 2.0
