dual atty dual 18650 box mod

[Jason365]

I have every thing i need for this. But need help on how to wire the atty connectors up with a 5 volt regulator. Can someone point me in the right direction or draw me up a diagram.

1 project box
2 18650 2500mah batteries
1 5 volt regulator

What atomizers are you using? you know with the resistance of TWO atomizers...you may pull down the voltage enough on its own that you don't even need the Regulator...

7.4v @ 6ohms = 1.23amps
7.4v x 1.23amps = 9.102watts
with one Atty

5v @ 3ohms = 1.66amps
5v x 1.66amps = 8.3watts

6v @ 3ohms = 2amps
6v x 2amps = 12watts

Odds are all my math and thoughts are wrong...someone who knows what they're talking about will step in soon

510's

So i don't need the volt regulator?

Please advise..

 

[vendo]

so do you want 2 attys running at 5V each?
Man thats gonna hurt 8-o
I would just run each battery to one atty each and fire it from one DPDT switch
Good luck anyway and let us know how it vapes

You mean a DPST, don't you?

 

[Jason365]

I was thinking 5v to each atty. Its big box mod. I want to make it worth it to pick it up and drip in 2 attys. It better pack a punch. Just need to figure out how to wire it up. Is it possible? I'm a total noob at electronics.

Hopefully someone can get me going in the right direction.

Hmm maybe
I thought that a DPST would combine the output. they (DPDT) are mainly used for reversing motors so you are right

Pending any better information from someone with more electronics know-how, I'd just wire it up as a normal 5v mod, but put the atomizers in parallel. I believe you could just leave out the regulator and put the atomizers in series, but then you're right back to 3.7v again.

What box are you using?

Ohm's Law tells us that with 2 resistors in parallel we use --

Rt = R1 X R2 / R1 + R2
3.0 X 3.0 / 3.0 + 3.0
9/6 = 1.5 ohms

Don't want that...

Vendo's suggestion of one batt to one atty makes more sense -- assuming the OP wants to draw off both attys at one time. Thus, the DPST momentary switch.

Two of those 18650s in parallel to one atty might be an interesting mod, btw. Could probably go a week w/o having to recharge batts. I could be wrong but I don't think that's been done before. It's an awfully big mod though...

i would like to see how you plan on putting these attys together, i have had a few ideas about this as well, having 2 attys just wasnt sure how to put them together to make it work...

i have a idea... ill pm ya lol

Why not? Shouldn't two atomizers in parallel just draw twice as much current? It would drain the battery faster, but they should both still work fine.

No, current splits when in parallel. Total current in a parallel circuit is a sum of the individual lines, e.g. if the source is putting out 5 amps, each atty would get 2.5ish

 

[boondongle]

I got a very different explanation in this thread. The poster indicated that two resistors in parallel would have half the resistance and draw twice the current.

 

[billyboy689]

two attys parallel will run power being fed from the 18650's wired in series , just keep the atty's well fed and let them cool if needed

why the need to use such large batts
you will get 4 hrs of quite heavy vaping from 2 x 3.0cr123's on dual atts

If you really want to choke a horse and insist on 5v for dual atties you could do this:

2 bats seperate circuits
2 TI booster chips
2 atties

A bit more money to build but the results would be easier on the bats and produce more vapor within seconds that it would humanly possible to take in (and more than any mod Ive ever seen built)

 

[caesar]

2 bats seperate circuits
2 TI booster chips
2 atties

This is the best suggestion yet.

If you go the regulator way, please use 2 regulators. 1 510 atty @ 5V will get the regulator hot, 2 attys will make it shut down.


PS: Mega don't: don't wire the bats in series and use 2 attys in parallel without reducing voltage. You'll kill both attys in an instant.

Yeah that's right. Sorry, total brain fart over here; I misread that as saying each line in parallel runs total current.

 

[morphector]

Why don't you do a 3 batts enclosure, put the 3 batts in series and the 2 atomisers in series so you'll be right around 5v for each atomiser

Using this example. Would I be able to use 1 switch? If so I think I can squeeze 2 booster chips in there.

Yeah..you would just run one of the source lines from both bats (both pos or both neg)

Make sure you put the switch before the booster in the circuit so that it is not powered up with no load continuously.
