FTFY 😎

This is part of the reason why Wh/mWh works better for calculations.

I agree with you here.
Energy (Wh) is a better reference for battery capacity in general and for multi-cell batteries in particular.

When initiating a multi-cell DNA device it's always a good idea to start by connecting it to EScribe and run the Battery Analyzer.
And then configure the mod to the obtained result (Wh).





According to Steam Crave's marketing, the LiPo packs present in this mod are the
Fullymax 1600mAh LiPo Battery Pack 4S 14.8V 30C

Specifications from the battery manufacturer:

Fullymax Professional LiPo Battery pack of 4cell
Capacity: 1600mAh
Voltage: 14.8V
Discharging rate: 30C
Max charging rate: 2C
Burst (3Sec): 60C
Dimension: 25*35*86 mm
Weight: 163g

1600mAh at 400W? Bet you'd get at least a half dozen good vapes before recharge time?Granted, I'm not an Electronics wizard...am I missing something???


Divide your average mWh vape into the batteries mWh rating (23.68Wh x 1000 = 23,680 mWh), subtract the circuits inefficiency of 3% (if I'm correct) although I generally use 20%+ being 97% is peak efficiency.
Edit:
As voltage drops efficiency suffers.

Ballparky with a 20 mWh vape would be around 900 to 1000 vapes, that's on the high side IMHO.


20mWh vape is about a .5 ohm 30x2 wrapped in 40awg SS316 at about 21 watts for 2.5 secondsish.

To compare convert mAh to Watt hours, it is 23.68 Wh

A Samsung 40T (4000 mAh) 21700 has 14.8 Wh

The elephant in the room, that no one said a thing about is: While all the banter about the mAh's and such has gone on, no one is going to vape at 400 watts. Well no one I've ever known has anyway. So lets say a person hits the fire button at 100 watts ( most people don't vape too much over this) for 3 to four seconds a vape. So someone do the math on that and figure out how long it lasts. The DNA Chip is a resourceful bit of engineering in that, if is pretty stingy with it's battery consumption. So any mathematicians want to find all the numbers and tackle the equation?
Vape on! It's the new healthier and more tasty way. Two things I can't help fix. 1: STUPID 2: Gloating! Both are proof of quantifiable idiocy. If you think you know everything! then we'll never agree.

Not my game, I've only toyed around with slightly above 100 watts.

Different resistances would throw slightly varying coefficients/tangient angles in the mix besides I failed my first pass through low volt, I could end up way out in left field!

I couldn't even imagine a 400 watt vape and really have no interest in trying it.
Edit:
As far as I know circuits like this are not exactly completely calculable, although it's possible to get relatively close.

All up in my head! LMAO!


Edited on 5/22/2021 at 5:18 AM. Reason: Guestimated 42ish vapes at 400 watts on a .19 ohm 19 AWG A1 quad coil. With the help of online calculators, because 42! ;0)

Not directed towards you, earlier the discussion was erroneously based on the idea that this was a "series" mod.

It's not, it's a DNA, that CAN go to 400 watts. It's set up like that naturally, nothing is required in Escribe for basic operation.

A 4s means, basically 4 cells. 3s? 3 Cells. multiplying the advertised mah by it's "S" designation is how we've done this for years...there is very little good info of the "interwebs", and most of it based on older LIPO packs.

6400 mah isn't that great, (little better than dual 18650 30Qs or LG browns...but it's a cooler battery, less internal resistance, and safer overall....and larger batteries may fit inside.

No one is going to need or use 700 Horse Power in their tiny Car, Yet A lot of people want/buy them!


A mod like this with a 4S 1600 Lipo will work great for some one who use's Big Fancy Coils & wants their battery to Last all Day!
My 4S 1300mAH DNA 250c gives batter battery life that a dual 21700 using the same atty :) Biggest issue with this type of mod is USB charging takes along time :(
