first of all i must say im sorry for repeating something that has likely already been addressed over and over but has anyone tried searching these archives? (especially from a phone as the computing method?)..i did try..but the answer keeps bringing up what the batteries potential to hold is and thats not the question..obviously the larger package has a potential to store more.. but if both batteries rate 3000mah 25amp continuous 50amp pulse is there a difference in performance between 18650 vs 26650.. my aegis (single battery mod) has the option to use prettt much anything up to the 26650 in size.. but it seems that advanced testing shows that even the ijoy26650 is a 3200mah average with a 25cont. average which is about equal to the top 18650 so is there a difference aside from size if all other numbers are the same? i know it seems like a stupid question but it really isnt.. you never really hear the word "sag" when referring to 18650s.. so does that mean they would perform better by themselves? (please dont confuse me by flooding me with info about the use of more than one at a time.. im talking about solo battery performance. sorry for the long post but i keep finding answers to questions im not asking so im trying to be clear.
