Parallel 18650 mods or high capacity internal battery mods

[rrayda]

I've been poking around and it seems to be super hard to find any parallel 18650 or high-capacity internal battery mods. I value longevity over power and therefore hesitate to get into the series 18650 mods. I'm currently running a VaporShark VaporFlask, it's got the dual 18650 parallel setup but the fire button is super-flaky (on my third RMA). So.... anything else out there with parallel replaceables or internal batteries in the 6000 mAh range?

On regulated devices the battery runtime of a parallel setup is the same as of a series setup (with the same power setting and batteries of course). In fact, bucking tend to be more efficient than boosting so series setups might actually have a slightly longer runtime, all else being equal.

What Ken said. With regulated the run times will be identical.

Istick 100 TC is parallel. I really like mine, price point is pretty good as well.

The Lost Vape Esquare (DNA 40) is a regulated parallel mod. I have three of them that I got a great deal on, and I really like them. Seems they're now out of stock wherever I look, though. Not sure if they've been discontinued or what.

That's interesting and totally counter to the way batteries normally work. Seems that the regulation circuitry modifies their electrical behavior in ways I was unaware of.

Are there many series regulated boxes that offer USB charging at high rates? I assume the voltage still stacks additively even with the regulation circuitry in the system....

The batteries are simply the power source in a regulated device. If the device needs more voltage than the batteries can directly provide, more amps are drawn to provide a higher voltage. If less voltage is needed, less amps are drawn. Thus it actually isn't contrary to how batteries normally work. If the atomizer needs 5v you're not using the full 8.4v of two batteries in series. Just like you're not using only 4.2v with two batteries in parallel when you need 5v.
