Can someone please explain to me the difference between batteries run in circuit vs in parallel?

[kathibg57]

I've finally decided I want a dual battery tc box mod due to the extended use time afforded by two batteries over a single.
However I need someone to explain to me, please using kindergarten terms, the difference between running them in circuit vs in parallel. I'm just not getting it and don't know why...(sorry if this seems basic to some).
Thanks!!

Hi, Parallel will give you twice the Volts and Series (not circuit, you might have heard wrong) will give you more run time....

You got it backwards. Parallel (side by side) will give you more runtime and Series (stacked) will give you twice the volts. I know it can be a little confusing..

Ok parallel your output voltage from each battery stay the same 4.2 fully charged. Your amp limit and mah rating double.

In series. You voltage output from batteries double 8.4v fully charged. And amp limit and mah rating stay the same.

Yes, in series your essentially stacking the batteries but they don't need to be physically stacked, can be wired in series. If positive ends of batteries go same way, most likely parallel, if they are opposite then most likely series. It's how your mod is wired simply flipping on battery doesn't turn it parallel or series, it's wired a particular way.

Parallel, same voltage as single, twice the current potential. Series, double the voltage. Usually cant change these types via the usb port if the device even has it. In a regulated mod, its not a big deal. Just make sure you put the batteries in correctly. Both will give you more run time, assuming the same output power.

Sorry, thanks for clearing that up

Ok, so if the mod info says to use 30A batteries or higher does that mean 2 of my Samsung 25A batts will work? (I'm actually looking into the IPV3 LI 200W tc and several ads for it have said 30a or higher and so I'm trying to decide between the IPV3 165 W tc that I've been told my 25A batts will be fine and the 200W!)

If you're actually going to use 200W there's really only one battery that will work and that's the Sony VTC4.

The 25R has high pulse ratings so it'd probably be OK which is how some people can use them but we never recommend using a battery that isn't rated continuous for your mod, in case a button sticks or something else goes wrong you could have a big issue. In other words the 25R can handle it under normal usage since you're only doing short bursts, but if something goes wrong it's already stretched so far you don't have much safety margin.

30 amp batteries (Sony vtc4,3 and LG HB6) are good for ~105 watts per cell. If you will vape near 200 watts, yes get 30 amp batteries. If you stay under ~140 ish, 20 amp batteries will be fine. The Samsung 25r (20 amp cells) will work fine up to around 140 watts.

Can a married pair of batteries from a paralell box be used in a series box?

 

[skeene]

does anyone really vape at 200 watts???

I see no reason why not.

IKR!

I can see it happening.

Built my Velocity with a parallel dual coil yesterday. 7 wrap, 3mm twisted 26AWG (x2) and 24AWG. Thought 60W would be Ok if on the cool side.... Nope, hardly anything. Starts cooking at 75W and vapes nice for me at 85. Came out to 0.16ohm. Just doable on a 30A cell tube, tried it with a HB6 and it was dead in half hour.

Can see some twin + core Clapton s needing close to 200W to get going. Would also need liquid nitrogen to cool them back down again lol!

I'm betting most mods will refuse to fire before you can get enough metal in the RDA to truly require 200W. Nice to have though.
