Battery test-review 18650 comparator
Put both the AW IMR 1600 and 2000 in that site and then look at the curves for 3 amp and 5 amps. You'll see that the 1600 holds a higher voltage longer above 3.7 volts. the extra run time of the 2000 under 3.7 volts is of no use to us in mechanical mods.
caught that just in time yesterday before RTD shipped out my batteries... they changed them to the 1600 mAh.. wee!
I too am waiting for my REO mail, so in the mean time just take the time and read through everything you can, I already feel like im reading to put this thing together and vape...only problem is it's not here yet haha
