They haven't made one yet to my knowledge. There's nothing that says it can't be done. The trend right now is getting more watts and temperature control out of a device. Most people are fine with just swapping batteries. Although running batteries in parallel would be safer it doesn't allow for the extreme high wattage people seem to be going after right now.

Actually battery life would be doubled juggler... When you run batteries in parallel you get double the mah. If you have two 18650 2000 mah batteries in a parallel circuit you have 4000mah but still 4.2v. If you run them in series you get 8.4v, but your mah is still only 2000. In parallel you also get to double amp draw of the battery since the pull is spread over the batteries evenly. For example you have two 20a batteries in parallel you can safely pull 40a. In short, series doubles voltage and parallel doubles amp rating and mah.

I am looking for a box mod with variable wattage,preferably capable of reaching 100 watts, that runs in parallel that can hold atleast two 18650 batteries.
Can anybody give any recommendations on mods fitting the description?
or point me in the direction of brands that build great parallel mods or VW mods?

the istick 100w does indeed seem to be parallel.

does anybody have one that can check with a dmm whether the two positives are tied and the two negatives are tied also?

Most of the regulated two-battery mods are series, although many of them can reach 100 watts or beyond. Some reason you don't want a series mod? How can you tell the difference with a regulated?

Many of us do not use series mods. Personally, we got away from the need to stack cells ages ago and series mods return to that. Stacking cells can be dangerous if you are not careful.

Series requires you to marry the cells, keeping them together and rotating the position of the cells (one in top spot gets more stress on it). While it gives you double the voltage, parallel gives you double mah and amps.

A wise person still marries the cells in a two battery mod, and I do not see how you can double the amps in a regulated box. That's what regulated means. You get the watts the chip will provide and no more. You do, of course, double the mAh, but this is also true in a regulated series box.

You can't double the mah in anything that is series, and while in a regulated device you do have the limits set by the chip, it amp load from the ohms still can stress the cells.

the trouble with parallel is, unless the mod does independent bays like the good chargers do, there is the eventuality of putting 1 battery in the wrong way, especially with flattops.
You only have to do it once on a Friday night to get some excitement in your life.

In the 3+ years I have been vaping I have never put cells in the wrong way, all it takes it paying attention to what you are doing.

Good for you.

With thousands of people changing batteries 100's of times a year in parallel-batt setups, how many 'incidents' per year will there be ?

Dual indepent bay chargers are common and not expensive, so to me it's worth it to buy independent bay parallel-batt mods. I guess it will just take Darwin a little longer before we see it.

We disagree about the first. Each battery has a certain amount of storage and a well-designed mod drains both of them evenly. Thus you get the mAh in both cells until you get a low voltage condition on the chip, no matter if it is series or parallel. I do agree it is possible to overload the batteries-- the chip does not know the R rating of the batteries you have installed-- but this only means you must use batteries of the specified amp loading. In any event, please yourself. I know of no mods approaching anything near 100 watts that are parallel. I also don't know of any mod regulation boards that will function to 100 W on 3.7 V. I guess, if you want a parallel box, you could build one with a DNA 200W board using three pairs of batteries in parallel, and series the pairs to make the 11 volts required.
