A "3S" replaceable Lipo in my efusion Duo.
And open
I can also swap in a 2 cell battery sled if I don't want to use the Lipo.
Is there a 'direct' upgrade to the istickTC40W ?

@Eskie he said multiple cell Lipos so I was thinking more than one bank. Like the Faux Mother Of Pearl though reminds me of my R150
Oh, got it. I just associate multiple cells in a Lipo as that's a standard way they're rated, in addition to capacity and all. Multiple physical packs don't make much sense for a mod design.
You can do it with a Lipo charger usually used for stuff like Lipo packs in radio controlled cars or drones. I always charge in mod as I don't have anything like that. I do like the fact that one day when the pack can no longer hold a charge, I can easily buy a replacement and pop it in. For me the advantage isn't in swapping them around, but in knowing I can easily replace it rather than have a good mod turn into a brick when the internal battery dies and replacement is fraught with the potential for failure on my part.
Just wondering. I did see that they have nice portable chargers now for people that carry a spare smartphone battery.
Oh, those things are great for usb charging phones, tablets, even mods. But you need a special plug type thingy for a Lipo to connect with. Unless you charge in the mod through the usb port. I've had one of those for years as they're great for traveling and not having to search the airport for an electric plug.
Probably work. I think you'd have to get some adapter from the Lost Vape Lipo plug to that box plug. There was some thread somewhere from someone who uses RC cars and got it to charge externally without a problem.
What's the atomiser in that photo?The Eleaf Pico does look nice, but doesn't the battery 'cap' interfere with airflow to your tank?
I can't think of any 'direct replacements' as eLeaf ventured into other formfactors after the TC40.
However the "pack of gum" size/shape can be found in the Joytech eVIC (internal battery) or VTC Mini (and VTC Mini2) (replaceable battery).

Two battery mods wired in series will have the same endurance at low watts as a single batter mod. A dual battery mod wired in paralell will give twice the endurance. If you can't do a watts law calculation from memory and know how the result applies to the particular battery and max power level you're going to use then avoid replacable battery mods until you do understand.
Now there will be howl's of protest that series mods give twice the battery life. Well, they don't. They give twice the voltage, which might be necessary for some builds and power levels. High voltage mods are inefficient at low watts. My single battery pico is a good solution for my 12 watt vape. I don't want the extra size and bulk of a bigger mod if I don't need it.
Any data to support that? The Watt hours are identical in series and parallel configurations, and bucking is generally regarded as more efficient than boosting. Experiences from specific individual mods don't mean much (for example, the iStick tc100w has better battery life than the Cuboid, but that's not simply due to parallel vs series), an actual scientific explanation is needed.

Try this link Why connect cells in parallel?
You asked for science. That would be an experiment, which I did. I have a cuboid (2 cells in series) and a vtc mini (single cell). They are made by the same company, have similar boards which include a puff timer. Starting with a new set of batteries I set both mods to the identical power settings, zeroed out the puff timers, vaped both until they quit with the same atomizer and the same build. They lasted almost exactly the same number of seconds on the puff timer. Anyone with those devices could do the same experiment assuming the power setting is low enough for the single cell mod. I used 30 watts.
In the example in your link the power provided in the parallel circuit is half if that in the series circuit. When you regulate the output, as you do with a vw mod, you're not simply providing all the available voltage directly to the resistor. Say that you have a 1 ohm resistance, an output of 30w, and two batteries providing 3v, with a capacity of 5 Ah (5000 mAh) each. In order to get 30w from the you need to provide 5.48v. You buck the 6v available from the series circuit, requiring less current than the full 6v. With the parallel circuit you need to boost the available 3v, which means that you need to draw more current.
Series:
6v / 5.48v = 1.095 * the available 5000 mAh = 5475 mAh
Parallel:
3v / 5.48v = .5474 * the available 10000 mAh = 5474 mAh
You don't actually need to know the resistance to calculate the amp draw though. You need the power and the available voltage.
Series:
30w / 6v (3+3v) = 5 amps
Parallel:
30w / 3v = 10 amps
So in the parallel circuit you actually draw double the current, but as you have twice the capacity the draw per battery is identical. This is, of course, before the efficiency of the converter is taken into account. Math doesn't lie.

I did the comparison. Ttwo batteries in series gave me the same endurance as a single 18650 at 30 watts on a 1.3 ohm stainless coil. The puff timer keeps track of the number of seconds the fire button switch is engaged. My Cuboid is in a drawer unused. I won't be lugging around two batteries to do the job of one. Do the same experiment and report your results.
You can't simply compare two devices and extrapolate that to relate to every device there is. My Smok Alien (series) has more battery time than my iStick tc100w (parallel), which has better battery time than my Cuboid (series).

But compare them is exactly what I did and found that carrying the Cuboid is a waste of effort an my watts. The VTC mini lasts just as long. When asked I searched for informed opinions and and posted a link. Nobody has to take my word for it. Do the experiment for yourself. If you have a single cell and dual series cell mods with puff timers you have everything you need.
