Help selecting a battery please.

To work out the amp draw on your battery divide the voltage of a fully charged battery which is 4.2v by the resistance of your coil.
You have to know the max amp draw the battery can handle.It should be on the battery or on any website selling it.
If you get your head round the above sum and do it for different resistance coils say 0.5 0.8 and 1.5 you will have an understanding of something useful.
