Dual atty, dual 18650 parallel unregulated box mod

[poyol]

Guys,

I have this mod (Triton) and I would like to know what is going on with my batteries when firing 2 atomizers simultaneously.
From what I understand, a parallel connection means my mAH is doubled, and so is my batteries' amp limit (correct?)

So let's say I was firing 1 atty on dual VTC5s, this means I can go for builds that draw up to about 40-50amps (correct?)

Now, what happens if I fire 2 attys together?

Reason I'm asking is because I want to try 2 super low ohm builds (0.15ohm or lower), but I would like to know how it's gonna affect my batteries first.

Not speaking from experience -

But it the box is wired batteries in parallel then both atties will be pulling from both batteries at the same time. If you built both atties with dual coils then the final load on the batteries would be that of a quad coil. So if each atty was built to .15 the final resistance load on the batteries would be .075

I plugged this in to steam engine calculator and this is the results

Ohms .075
Voltage 4.2 V
Current 42 A
Power 176.4 W

Ah okie... So I guess it's not safe to be loading 2 attys with a 0.15 build each?

It is my understanding that wired in parallel the .075 build will pull 21 amps from each battery. As long as the batteries your running can handle that it should be fine barring any unexpected shorts. The VTC5 are 30 amp continuous and should handle it. Also spend some time in the battery area and read up on all the battery safety you can. The world of unregulated mods is great but one must use caution and understand the limits of the batteries they are using.


2 batteries in Parallel = take half the amp load and that is what each battery will be supplying.

4 in paralleled would be each only taking 1\4 of the total amps

I see..

So what I should be doing when running 2 atomizers is;
1) take lowest ohm reading and divide it by half
2) calculate amp draw based on result in 1)
3) divide calculated amp draw by half
4) ensure battery is able to supply the calculated amp draw in 3)

I think..

If we are on the same page then this

Build one atty and meter it to find the resistance. Divide that by half.
Find the amps that will be pulling and divide that by half.
If your batteries can handle this load then move on to building the second atty.
build the second atty the same as the first meter it to verify build.
If everything went right you should now be able to put both atties on the mod.
Adjust so that all 4 coils fire evenly
I would then recheck the resistance as the adjustments can change the resistance and verify that you are not over taxing the batteries amp limits. ( i would meter both atties again just to be safe)
Then vape away

seems confusing but once you build it a couple times it will become much easier.

Yupp, pretty much on the same page here.
But you're right, taking the reading before building the next atty is the way to go
