Exotic coils like claptons as opposed to simple round wire coils will contain a lot of metal and as a
consequence will have a low resistance. Please go back and read what I posted and specifically the article I linked to.
To reiterate, for all intents and purposes a regulated mod does not care what the coil resistance is. You set the wattage, and the mod delivers this wattage to the coil. You may be getting confused with unregulated devices like mechanical mods where the coil resistance is what dictates the power level.
To answer your question about how this pertains to your batteries on a regulated mod, the wattage you select will dictate the amp draw
not the coil resistance. Have a read of the article below to see how this is calculated.
