oh man my brain is starting to hurt lol. I think I know what I am looking for now I basically want low mah and a higher amp battery for my needs. going to do more research and look/play with all the links thanks for the help
Regulated mod, the formula is pretty simple, basic "Watts Law"
Power (Wattage)/Voltage=Amps
For a regulated mod, we use the lowest battery charge in voltage for this formula, depending on the mod this can be between 3.2 to 3.6v per battery before the mod electronics give a low battery warning or shuts off, we call this cut off voltage, so using the lower range that most mods use, 3.2v
Single Battery Mod
30watts/3.2volts=9.375amps
Snow Wolf being a series dual battery mod, in a series voltage is doubled, but the mah and amps of a single battery are the same.
30watts/6.4volts (3.2volts X2)=4.6875amps
Fresh full charges as examples only, fresh charge with 18650 batteries is 4.2v
30watts/4.2volts=7.1429amps
30watts/8.4volts (4.2volts X2)=3.5714amps
hth for in the future, also link is my signature goes to a blog I've done explaining some other things, breakdowns by wattage category, links to Baditude and Mooch's blogs, and a second blog post I did explaining single, series, and parallel battery circuits.
+1 on asking questions as well
