Hi. When im running a 0.12 ohm build, taking 2-3 second pulls on a single 18650 mod(unreg) do I calculate the amp draw b4 or after sag under load? Meaning my batt is @ 4.15v at full charge, but at that super low build, and batt sag, voltage drop, drop under load, im probably really hitting 3.7v when I press that button, so do I calculate 0.12ohm @ 4.15v to get amp draw, or 0.12ohm @ 3.7v?
