just got a DNA75 Hcigar VT75 nano. Tried to set up in escribe to show the USB charge current on screen. But unlike my old DNA200, I see no option on the dropdown menu to show "USB CURRENT", only "Current" which apparently isn't USB current, whatever "current" is, it stays at 0.00A while charging. I just like to see what Amps the usb is charging at. Max is 1.0A on a DNA75, correct? But DNA250 max USB charges at 2A, correct? But then how come my new Hcigar vt250s DNA250 is only showing max .95A when using a 2.1A wall adapter? The USB cord I'm using can't supply 2A or something? One last thing for now, Under MOD tab I have my old DNA200 triple 18650 mod set to the following which I think someone told me in the past to do: Battery capacity: 33 Wh 3 cell Soft Cell cutoff: 2.8V Charging Mode: max recharges (instead of max puffs). Should I set my new DNA250 and DNA75 mods also to Capacity 33 Wh, and set soft cell cutoff to 2.8V? I know what max charges and max puffs means, but not sure about 33Wh is. At default the DNA250 is 9wh. the DNA75 doesn't even show anything there for Wh. And soft cell cutoff at default is 3.09 V on the DNA250. I'm using dual sony vt6 3000 mAh in the DNA250 by the way, and a single 18650 3000 mAh LG H2 in the DNA75. And I plan to only ever charge these via the MOD's USB. It's just safer to make soft cell cutoff lower than the default 3.09V, but it's kind of like max recharges vs max puffs in that you don't stress the batteries as much and therefore get more months out of them vs more puffs between charges? Don't these cells charge to 4.2V on an external anyway? Why is default 3.09V so much lower than that though?
