  1. I've searched all over and can't seem to find an answer to this question. When batteries are run in a series circuit like in my new tesla 160w box mod what value is used for voltage in the equitation I was taught for calculating discharge rate? I was taught discharge rate = battery voltage / resistance of coil (ohms). The batteries I'm using are Sony vtc4s. Their max discharge rate is labeled as 30A. If I'm calculating for the highest draw I'm likely to put on those batteries I'd divide by .18 . But I'm assuming I'm dividing 4.2v, the high end of a fully charged 18650 Sony vtc4. Doing that gives me a discharge rate of 23.33A which is well within the limits of the battery. But these are run in series in the tesla 160w box mod so that creates 8.4v at max charge. Using that voltage in the above equation gives me a discharge rate of 46.66A......well above the rating of the battery. I know this is a regulated mod and won't fire in dangerous conditions but I was more concerned about my math and the values used to calculate discharge rate in mods with batteries run in series circuits.
