So I only ever use single battery mechanical mods and I usually built around .3 for them because that's where I find it to be satisfying and where I feel confident. But could someone explain to me why anyone would want to use a dual battery series Mechs if it limits you even further in what you can build? I would have thought that using two batteries would take the strain off the battery not add more strain to the batteries if anything. Also I believe this chart is going off 4.2 which most people don't go off of that's like super safety mode most people go off 3.7. I'm never going to buy a dual battery series mechanical mod I have no interest it doesn't fit a need that I have but I just can't wrap my brain around how that works why a dual-battery becomes more risky somehow with your build and you have to build higher for it. Like I do occasionally use a mechanical mod and I know how to use the calculators and I know how to look up the ratings for mooch but I don't really understand the nitty-gritty of why dual battery would cause such a problem that you had to build higher.
