Yihi SX Mini Q-Class

[Nath89]

Hi, new to the forum.

Not very clued up with batteries so thought I should seek advice from the more experienced. . . .

So which batteries are going to be best for this mod combined with Aspire Atlansis v2 running either 0.3 or 1.8 equally.

Thinking I need a general all rounder?

:/

Cheers

I personally have a preference for the LG HG2 batteries, other people may have a different choice. They are a good 20A battery with a 3000mAh capacity, and work well with any tank, including the subohm tanks.

Always buy from a reputable dealer, and never buy batteries off of ebay.

Thank you for the reply, I was just about to edit. . . can you suggest any reputable retailers for these.

I agree with @FXRich I really like the HG2 or the Samsung 30Q.

Before I make too many suggestions, I should let you know that it really depends on the Wattage you run it at.  Your coil resistance has little/nothing to do with the draw on your battery.  The Wattage/Joule setting determines how much amperage you are pulling from the battery.

If you are running it at full capacity (200+ watts)  

I recommend you not using anything other than:

LG HB2, LG HB4, LG HB6

They won't last long, but will be the safest choice.

If you are running 150 watts down to 100 watts:

Sony VTC5A (not the VTC5)

Sony VTC4

LG HD2

Less than 100 watts:

Samsung 30Q

LG HG2

Samsung 20R

LG HE2/4

I would buy them from one of the following:

Here is a great chart for batteries:

I think Jason meant the Samsung 25R2 (blue) / 25R5 (green) --- Just FYI

Although the 20R are good 22A batteries, they are just hard to find (at a reasonable price)

Yes!  Sorry about that.  My dad came over mid-post, and I got distracted.

 

Thanks Earthling!

I think I should also add that I personally would not run any 2 cell device over 180 watts.  This is 90 watts per cell.  90 / 3.2 = 28.125 * 1.1 =  30.9 Amps.

Does it matter if the dual battery mod is series or parellel? I may be mistaken, but I believe there is a difference....

Only if it is mechanical. 

If it is wattage or TC the math works out the same.  180 / 6.4 = 28.125 * 1.1 = 30.9 Amps

Your voltage is doubled on a series mod but your amperage capacity is averaged.  With a parallel mod your voltage stays the same but amperage is doubled.  Either way we are only asking for Wattage out of the batteries so:

100 watts:

100 watts to atomizer with a .5 ohm coil is requiring the board to supply 7 volts

Parallel batteries at 100 watts have a low cut off of around 3.2V (on most mods) in order to supply 100 watts it will take 31.25 amps to supply it.  An "average" board is only about 90% efficient so we add 10% so it takes 34.375 amps total.  In a parallel circuit it divided equally between the batteries or 17.1875 amps each. (100/3.2 x 1.1)/2

In a series circuit at 100 watts with a  low cut off of around 6.4V (voltage doubled in a series) in order to supply 100 watts it will take 15.625 amps to supply it.  An "average" board is only about 90% efficient so we add 10% so it takes 17.1875 amps (100/6.4 x 1.1)

Sorry, I am sure that is clear as mud....

Thanks, I'm no electrical engineer but your explanation makes sense.

Thanks for good and reasonable explanation. I hardly consider myself as a completely dumb, but all this physics and electrics frighten me a little bit, a nice example is always good to understand the subject in question. High drain batteries http://gypsyvapes.com/batteries-E-Cigarette-vape are good to me, they surely can provide enough amps for a long time.
