Yes, higher mass coils will require a lower TCR which in turn will mean a lower difference in temperature of the coil to temp of the load.
Well, since you were able to persuade the willing, with your implied promises of glow-free vaping possibilities with the stempod using alternate coils, you got me to go ahead and pre-order the stempod a few days ago with hours left before the sale ended. Now I'm looking forward to getting this thing in the new few weeks and trying it out!
I'll probably try using it, as-is, with your pre-installed notch coils for a few times at least; I'm not scared of a "little" glow, (but prolonged? idk?) but after I prove the stepmod to myself and get used it to, I'm looking forward to trying alternate builds to see if I can get it to vape nicely with some ceramic donuts and rods, perhaps, or some thicker pre-made coils I have lying around. Dan, it would be even more taxing on the battery cell, but maybe we can vape with the stempod using
quad notch coils so nothing has to glow? (assuming 4 can fit in there? Maybe vertically oriented? The possibilities!
)
Your stempod deck is similar to these smok X-baby RBAs I use, I'm already thinking of so many stempod-deck builds....

I don't remember if I have a p/I for tubo fw but with Arctic fox I have it on. Pretty close to stock values, smooths out the curve enough for me
Good to know about the PI control, I find that 510 atomizers almost always work better with this enabled if you can dial in some good values. I hope you'll share your exact #'s when the stempod drops, since you aren't shipping out pre-configured TC mods like how a tubo evic is.
Guess this
Dicodes Dani 25, a 25mm German high-end mod would look nice with the StemPod
Would look nice? Yes... it's even a thick 25mm tube I think so the stempod would have minimal overlap. But the
$300 price tag sure doesn't look nice
I was shopping for a TC tube mod a while ago as soon as I found out they existed! Even dicodes' older TC-tube models retail for well over $100. Although they seem top-notch in that class of device, (not a crowded field?) with good chipset, options, user-programmable TCR, etc, I can't justify paying that much for a tube mod, or any TC mod!
It's much more modest and basic, but I settled for an ehpro 101 50w TC mod instead. For a measly 20 bucks, it does basic TC functions decently for me; it allows me to hold the button down and not burn the contents of my atomizer, it lets me adjust the temp with some control & reliable effect, that's the basics of what a TC mod should do for you. It lacks user-set-TCR, which sucks, but if your atty can work in TC mode, you can always compensate with trial & error. For example, I use the ehpro 101 with a DTV3 10mm donut, which has NiCr leads. This is not the same as the SS, Ti or Ni pre-sets. But by using the TC-Ti mode (usually pre-set to TCR # 300-400 if 1,000 is "max") in place of TCR #200, which I would set, by simply moving the temp up from low 200's F until I got good vapor, I found that 280F warms up my donut to roughly the 390-400F temps that I would accurately see on my screen if I could set TCR 200. No big deal to me.

Hoping this thread blows up as more people get their Splinters, Modpods, etc. In the meantime I'm looking for a starter mod for the above. Will something like this work out of the box?

Any downsides? So green when it comes to mods...
Edit: it's a Joyetech but not on "the list"
So I grabbed this from the
"what box mod are you using" thread since there is a lot of relevant cross-talk about the stempod as well.
@dodgy_b, I personally would not recommend the evic primo mini / se, I have 3 of these little mods, and they're actually kind of nice and have some good parts, mostly aesthetic. Nice big screen, easy accessible buttons, nice grip & feel in the hand, and good looks (to me at least) but it has one major flaw:
poor battery discharge capabilities 
I bought my first primo mini SE to run a heavy dual 10mm ceramic donut RTA I made; I wanted to run @75w on a 0.36 ohm coil for a quick warmup, which amounts to about 13-14 amps to the coil. I found out the primo mini was not letting me hit my coils with that high amount of power, it was saying "battery low" very early, even with fully charged cells. I tried many batteries, 30Q, 25R, VTC5, even VTC4, this mod was not letting me fire the full 75w I wanted, even with high CDR batteries! I had to settle for 60w, and 50w at 50% charge.
I was talking with
@KeroZen about this a while ago and he thinks I'm just running into the limits of a single cell!
Partially true, but I later tried using the same builds on my other single-cell mods like a VTC mini or an eleaf pico 75w, and my dual & quad donut builds at around 0.3-0.4 ohm would fire just fine, even with an aged battery, no complaint of battery low!
I even tried running a DT Gen2 dry herb atty, only 0.8 ohm, on a newer primo mini I bought. Only 40w, a mere 7 amps to the coil with a brand new VTC5 battery, it would say 'battery low' and refuse to fire when the charge was under only 80% or so. (weak
lame) Plug the same atty to my VTC mini, it fires 40w easy, no problem, all the way down to 20-30% charge left , no complaints from the mod.
I was reading on the AF forums about this issue, some have speculated that the meager-sized, gold battery contacts / pins for the cell on the battery door of the primo mini are the cause of this. Compared to the big, beefy gold contacts for the cell on the VTC mini, I see this may be the case.
Long review, but basically;
primo mini: it's a nice mod, but it sucks for hi-amperage draws! With the stempod being 0.2 or 0.5 ohm, this mod may leave you with "battery low" errors even when you may have 30-50% charge left on your cell, so I would pass on this one! Too bad...
Oh, I also wanted to ask. RBT says the Splinter is rated for 50W max & a 30 sec. max draw. What is the StemPod rated for? I assume that both are contingent on what coils are used? So what are the rating for the stock coils? Don't want to cause any damage. Thanks!
I probably shouldn't talk
too much on Dan's behalf, but if you use the stempod properly on TC mode (as intended) there should be no "max draw" duration. Whether you use it "on-demand" or have it set up with FJ's cruise mode on tubomyevic, the mod will only send as much watts as needed to maintain the set temp to the coils, and not more than needed. So if you stop your draw but leave the stempod cruising in your hand or on your glass piece, the watts will bounce low to maintain coil temp. When you start drawing again, your air flow cools the coils, the mod can notice this, and it pushes more power to the coils to match you. It's almost like "draw detection" and FJ even implemented a feature like this in tuboevic called "eco-cruise"
If you are using the stempod for heavy, back-to-back sessions, it might tax the CPU on the mod and the battery temp, to push a "device too hot" message like some heavy tubo users see, but that is quite variable, and not directly related to how long you draw.
So "max draw" would probably only apply to watts/volts mode vaping, which, we're being clear here, is not recommended for this device!
And just in case you do "burn out" your coils somehow, or they just get worn out, it should be super easy & cheap to swap them out. Inflicting mild damage to the coils from overpowering / overheating them shouldn't ruin the rest of the stempod body, I would hope!
510-convection vape with user-serviceable coils, I wish I could do this on my tubo-evic
