Ohhh thanks a lot! So meaning if i have 3 batts in parallel then i can build coils that require even above 30amps cdr?
You can, but there's no real sense in it. You won't find a parallel regulated mod, or not many, (the calculations are different anyway) because voltage is easier to manipulate, so series is the way to go for that. A three-battery parallel box mech mod can, theoretically, take a coil down to .07Ω to make 60 amps on the load, but that is both insane and useless. A .07Ω resistance is the value battery testers use for
dead short testing, for one thing. For another, once you get below about .2ish ohms, you start getting large efficiency losses (I²R losses) so great any actual improvement in watts is wasted and not applied to the coil, no matter how many batteries you have. On a mech, you're really limited to 85-90 watts in practice no matter how many batteries you maze up, and you can get that on a two-battery box.
The one thing you can do with multiple battery mechs that can increase your cloud without serious danger or wasting all the extra watts you're generating, is to build an atty that will take 6 or 8 coils. But bear in mind, if you have an octo-coil atty, and you stay at .2Ω, each individual coil has to be 1.6Ω. In practical terms, a regulated mod, with the capacity to increase voltage above battery volts, can more effectively use tall watts than a mech can. And, in general, a massive, huge surface area coil can make better cloud than a multitude of smaller, slick wire coils, at the expense of some ramp time to heat all that wire up. It's not about watts, or not entirely. It's mostly about power radiated from the coil surface in contact with wet wick, and there's more than one way to get there.
