I have a small R/C helicopter that uses 3.7v lithium polymer batteries. You can buy batteries with a higher mah rating. Often times the batteries with the higher mah rating will also have a higher (C) discharge rate, so they run the motors a little faster. Is there any variance like this, for example, in an ego battery. If I have a smoktek 650mah battery, will it have the same discharge rate as a 1000mah battery?

You question is a bit confusing, but the actual "(C) discharge rate" in that case probably makes no significant difference in the vapetime, but the mAh will.

Take a peek.

That's a healthy 3A drain test (a 1.5Ω atty draws ~2.4A). The AW has a much higher 'C' rating, it's rated for 10A, The Sanyo on the other hand is rated at 5.2A. We see from this test that the Sanyo's mAh easily trumps the AW's higher 'C' rating while also maintaining higher volts.

Sorry for my poorly worded question. I am asking about available amperage to the atomizer. If a particular atomizer would draw 2.5 amps @ 3.7 volts, but you are using a battery, that is regulated at 2.0 amp discharge rate, then it would not fire the atomizer as hot as a battery that was rated @ a 2.5 amp discharge rate. Thats why I was wondering if the higher mah batteries had a higher discharge rate. Thanks.
