3S lipo mAh readings = 3x equivalent 18650/26650, BOGUS!?

[Rivas]

first it's not the mAh it's the volts, volts are not in anyway related to battery life.
3S lipo batteries are made of 3 cells connected in SERIES, so mAh is not affected by any means. ONLY the volts.
Through simple knowledge in physics: the majorly used battery -the 900 mAh one- will only last 45 puffs on 200 watts if the puffs are deep 5 seconds each; and even the best would last 320 of the same puffs.

I am dead sure of my calculations, and accordingly I think the DNA 200 is of little use for now. we have no batteries that are up for the challenge. at least my challenge of 700+ puffs in one setting cause that's the amount of puffs I am used to while smoking shisha.

I need you're opinions and proof that I am wrong.

Watts are a combination of volts and amps. Lets says we want to make 50 watts.

50 watts = 4 volts x 12.5 amps
50 watts = 8 volts x 6.25 amps
50 watts = 12 volts x 4.17 amps

As you can see, increasing the volts you use to make a certain amount of watts reduces the amps required which increases battery runtime. In a variable power mod, input voltage absolutely affects battery drain.

Depends on what box you're looking at. The VTBox200 holds 3x 1800mah battery. So if you go small (lava box, VS, hcigar) then yes, you can fit a 3 larger lipo batteries in there.

Don't like that? Spend more get a triple 18650 DNA200 mod.

Batteries real life and total energy consumption is measured in X watt-hours, not amps; watts in an "HOUR" , X watt = X x amp x volt and by an hour you would have spent X watt-hours ; so still no difference! but I kinda get what you're saying but still at 200 watts there is no sufficient compensation like it would be much better if the DNA 200 chip can understand 6S lipo, I would have took a WAY DIFFERENT stance.

Mah and nominal voltage combine to give watt hours. We only talk about mah when discussing a cells capacity because the cells we use all have the same nominal voltage. The fact is two (or three, whatever) cells gives you longer runtime than a single cell at a specific watt setting in a variable power mod. Parallel, series, doesn't matter. More cells last longer than fewer cells. How you configure the cells depends on the input voltage requirements of the chip being used.

resistance and voltage are the factors of the DNA chip, but what I am saying is that a max of 12.6 volts would not lower the amps sufficiently in case of setting the device on 200 watts; that's why I insist that the DNA 200 chip is not convenient like previous dna chips.
I will be working on a gigantic mod though that's some-what up to the challenge *will weight 1.5 kg or 3.3 pounds and -to my needs- I will charge it once a week if I ran it on 40 watts *

I don't think you understand how variable wattage devices work. At 200w of output and 11v being supplied to the chip you're drawing less than 20a from the batteries. 12.6v of input voltage lowers the battery current even more at the same 200w.

V*C=P, max V output is 9 so C needs to be 22.22 x 1 hours = 22.2 amp-hour; you only have .9 amps-hour; please explain more then!

Like I said, you don't understand how these devices work. In order to get 200 watts out of the chip, you have to supply it with 200 watts (plus about 5% for convertor loss). The load placed on the batteries is the chip, and the load placed on the chip is the coil. 200w of output from the chip to the coil needs 200w of output from the batteries to the chip. The chip takes the 200w it gets in one combination of volts and amps and converts it and outputs it to another combination of volts and amps to the coil. To get 200w from batteries that are at 11 volts the chip pulls 18.2 amps. 11v and 18.2a give you 200w. Watts in equals watts out.

Who vapes at 200w anyways?...lol

Please post a vid of multiple 200 watt pulls

that's exactly what I was saying the .9 amp-hour battery can't support 18.2 amp-hours cause it only has .9 amp-hour

Who vapes at 200w anyways?...lol

that's can conclude that DNA 200 has no usefulness

Your initial post said adding batteries in series doesn't affect runtime. In a variable wattage mod, adding batteries in parallel OR series increases the amount of time you can vape at any certain watt setting. I tried to explain why that is. What you're talking about now is beyond me.
