[AXIOM_1]

That's what I assumed, but he stated it as parallel and so I was stating this so that he may know that it's probably series.

 

[AXIOM_1]

Okay so now one is able to explain it because somewhere down the line( I am an okay vaper. I know most of my stuff) I need a good starting point. I have the Samsung r 18650 batteries. Dual parallel in a Dimitri box mod. 4.2 volts each that comes out to 8.4 volts total right?

Just another thing I forgot to mention for you or others here: Concerning voltage, whenever you have batteries connected in parallel (both positive posts connected together and both negative connected together) and provided that each battery is of the same voltage value, then the total output voltage will be that of a single battery.

A series configuration on the other hand acts entirely different: When the electron flow from one battery travels through the other battery, they are connected in series, in which case the voltages of the batteries will add providing that the negative polarity is connected to the positive polarity of the other battery. In a series configuration, if you were to reverse the polarity of one of the batteries so that the negative lead was feeding into the negative lead of the other battery (bucking each other), then the net output voltage would be ZERO volts..... It would be exactly like you had no battery at all. This of course is provided that the battery voltages are the same.......... If you had say a 5 v battery and a 2 volt battery connected in a series configuration to where they are bucking each other then the output voltage would be 5v - 2v = 3 volts......But, as far as mods are concerned you will probably never find series connected batteries that are bucking each other..... So, you can assume as far as mods are concerned that all series connected batteries have voltages that will add to each other.

You're right, of course, but he's not, or not according to the website. The Dimitri is a series mod...

Okay every video I watch and every thing I read states that it is a parallel and I was far certain that it was. Now im concerned

So am I, now you say that. The only link I have found for it that says one way or the other is this one, and it says it's series. The exact quote is "This box mod delivers outstanding battery life, housing two 18650 batteries in series." It is going to be important to know that. Do you have a voltmeter? If so, measure the voltage at the 510 connector and then you will know. If you get 4ish volts with 2 batteries in it, it's parallel, and if you get 8ish volts with 2 batteries in it, then it's series. All the rest of our conversation still holds. If it's a series mod, and you have 2 20 amp batteries in it, you should build your coils for 8.4V and 10A. If it's a parallel mod with two batteries, build for 4.2V and 20A. Parallel holds battery voltage and doubles amperage. Series holds battery amperage and doubles voltage. Depending on how the mod is built-- I can't see that from the photos-- it might be parallel if you put the batteries in both the same way, and series if you put them in opposite from one another. It's perfectly possible to build a 2-battery box mod like that; I have done it myself. I'm afraid you're on your own about that, I can't see what you have. Hhhmmm... you could take pictures and post them here; that might tell me something.

Dual parallel in a Dimitri box mod. 4.2 volts each that comes out to 8.4 volts total right? I was told my 1.2 ohms is better than .5 ohms. Why? I have a Dimitri mod (as I said and if it helps anything, unregulated like I like them) but what would be a "better ohm" to vape? I DO NOT go very low. I barely even used my .5 coil just cause of what I was told. Am I wrong? should I switch them up or rebuild another coil?

your question is a little confusing. the Dimitri mod like most 2 cell mods is a parallel mod giving 4.2 volts and not a series mod giving 8.4 volts. the actual voltage under load with a fully charged battery will be closer to 3.7 volts.I have found that many flavors do not like heat and lose their complexity and subtle undertones in high powered sub ohm tanks. a 1.2 ohm coil will give you better flavor and a 0.5 ohm coil will give you more vapor production and a hotter vape. so what you choose will be based on your personal preference.if you want flavor then use the 1.2 ohm coil. if you want clouds then use the 0.5 ohm coil even a single battery could safely handle either coil

Yes It is parallel. Both batteries are in the same way. I am looking at my buddies considering I don't have mine on me. I have a volt meter and checked everything out just to say I have done it. I thank you all for being such a great help and not rude like most the people at the smoke shops here. I greatly understood everything mentioned and it pushed my knowledge further unlike whenever I ask a question people slam in my face to stay on regulated or egos. I have taken great notes and it comes out to about 3.8 volts is easily working with both coils. For my .5 I just use a different juice that is less flavorful so im not worries about constantly dripping and saving that flavor.

and I guess one last thing

so I have this diagram saying I get 20 amps for one and in parallel I get 40 amps. Does this mean I still wanna stay under 20 or is my new limit "40"?

Excellent, dude, we're really smoking it now Ok, parallel it is, and that diagram is perfectly correct. In a parallel setup, you get battery voltage-- that's 4.2-- and double the amperage. With the 25 Rs, that would be 40 amps. Bear in mind, though, that's a maximum. I, for one, don't recommend loading them that high. I would really recommend you stay under 20 amps. Really, I don't think that will be a limit for you, you could then build down to .21 and 84 watts. If that's not enough for ya, you need a three battery mod, lol But you have a lot better understanding of it now, and know about the calculator. It's your safety, so you make the call. That's probably the number one lesson in mechs anyway: the only safety you have is between your ears. Good luck, dude, and holler again if we can help.

Thanks so much. definitely the best man out there and by far the most knowledgeable. Thank you for your time. Have a great one and Vape on.
