1 180mah battery 510 SR Atty
1 900mah battery 510 SR Atty

Would there be a difference in vapor or would it be the same.The reason im asking these questions is because ive tried a few devices not on different voltages as im just getting into that.So how can people say one device causes more?

If the same battery technology is being used, when freshly charged you wouldn't expect a difference - the bigger battery would supply its best performance for far longer though - the little one would drop off rapidly... (With the caveat that Dave mentioned though - in the case you have picked that shouldn't be an issue)

The best decision I made when building my mod was parallel 18650 batteries - that initial sweet spot seems to go on forever.
Haven't tried expensive batteries yet since they do cost a damn sight more and for parallel I don't know how much difference they'd make.

Yesterday I used the device for about 5 hours of use and at the start the voltage was 4.14 and at the end 3.86 which I thought was excellent. That was about 4 ml of juice gone through on a 2.6 Ohm Clearo tank though so that's nearly 6.5 watts but I didn't measure voltage under load.

I have the Goliath with two 18650s working in parallel.Standard Trustfire batts were giving me a good vape but when i added two AW IMR 18650s i couldnt believe the difference.It certainly vapes alot better using the high drains.

Duly noted Ian, I shall have to save up for AW's then for Monster Mod, wonder how the charging circuit will do with them - can't imagine there would be a problem as its basically a trickle charger.

If im perfectly honest Verey,the monster mod is one of my favourites.It vapes amazingly and i use it a hell of alot for the big run time,i find it very reliable and it never misses a beat.I also love the touch sensors on the mod,if it had a kill switch and direct charging point then it would be my main device.

[vereybowring]

My build doesn't have the touch sensor but I could fit one if i wanted but going down the simple mechanical button route - but one not involving springs, just natural material tension.
With the circuitry for the touch sensor already in your Goliath I don't know if there would be room for a charge circuit but a kill switch could be added at the side with a bit of effort.
I do love Monster Mod V1.1 because of the power and the fact that I can use it for about two days and then plug it into a usb and it's almost fully recharged by morning - and it even charges (albeit a bit slower) if I am using it - not full PT though.

[ian]

It really is a great mod and testament that vaping doesnt need to get expensive.With the two AW IMR high drains im getting amazing results and as you say atleast two maybe three full days of heavy vaping heaven.I love the tanks on it,vape is totally flawless,im awaiting the Gemini from Sean now Its the Goliath case and same battery set up but with two atomiser connections for double barrel vaping.I think Sean plans to add a kill switch and button instead of touch sensors,i cant wait for this mod I know battery life will be cut to about a day but having two LR cartos going at the same time will be a cracking hit.

2 LR cartos at the same time

Just the one knocks my block off

In both cases, you'd be drawing close to 1.5 amps - slightly higher at 4.2 volts freshly off the charger. However, the 180mAH battery would be depleted in short order, and the output voltage would drop from 4.2 volts to 3.5 very, very quickly. So, straight out of the charger, the first few drags off both would be pretty much the same - but your 180mAH battery will very soon wimp out (in fact it will last for no more than fifteen minutes - or roughly 80 drags). Your 900mAH (assuming it's not an eGo 900mAH) will drop voltage very much less quickly, and will maintain the "better" experience for longer - roughly 400 drags until it's depleted.

If, however, it IS an eGo 900mAH battery, then it will start at 3.4 volts, and stay there until two drags from it ceasing to work at all, as it's a voltage regulated device. It will draw a current on just over 1.4 amps, and deliver a wattage of around 4.75 watts right the way through. And, strangely, give you more drags - closer to 450...

Novelty really Bucko but i often vape two devices at the same time and love the hit.It will be a device i turn to in those very stressful situations So it may well be used as my main daily vape the way things are going lately

[buckowski]

Dave,
You're clued up on voltages, what's your view on the dual coil cartos being used on regular tornado/Ego's?

Do ya reckon they could blow up in yer face, or is it a worry about nowt?

That bad eh, sorry to hear it mate. sounds like ya need that LR double barrel

I don't think there's an issue, really. At 650mAH, the DCCs aren't going to stress either an eGo or a Tornado too badly - the current draw will be around 2.25 amps delivering just over 7 watts, so the batteries will be running at 3.5C or just under, which ought to be OK ("C" is the charge rate or discharge rate, depending on who you talk to - basically, 1C (or just C) is the amperage the battery will provide if fully discharged in one hour. So, in this case, we're discharging the battery at 3.5 times that rate - 3.5C).

However, the caveat is that the lifespan of the battery is quite likely to be shortened. Batteries much prefer to be discharged as slowly as possible. Give them too much work to do, and they have little breakdowns inside that increase the internal resistance, and also decrease capacity for holding charge. It's a trade-off, but one I think is worth it.

[buckowski]

Thanks for that Dave.

I've always used LR atties on me tornado's, no problems with those.

So is it right to assume these 1.5LR dual coils use the same amount of power as a 1.5LR LR atty?

[hifistud]

It is, yes - current is dependent on resistance, assuming constant voltage - Ohm's law applies, and ye canna change the laws of physics captain...
