here's the calc for ya:
volts/ohms * volts = watts
Thanks for the formula.
I knew my numbers were off, but wasnt sure why. Been using posted charts as a reference. Lets see 5v/3.2ohm*5v=7.8 close to the sweet spot.
Now lets see if my algebra still works. 3.7v/7.8watts*3.7v=1.7ohms
So to match my 5v PT i've got to snag a 1.7 ohm cartomizer and hope the C on my battery can handle it. Worst case scenario I have to get an IMR 18500 instead of the ICR 18500 1600 mAh I've already got. Back to the battery library as soon as I place my order.
Study hard and you to could become a PV master.
The technical information around here is wonderful. I just needed someone to tell me the sweet spot was 8-9 watts and I could have no fear of torching my juice with that souped up mod of mine.
