I have some non AW batteries that I have run in my Reo...
A Sony VTC 4, Samsung 25R, Subohm 35amp, and an LG HE2. In addition to that I have 6 AW1600s.
I can attest that the above non AW batteries are all 3-6 months old and all are a disappointment compared to the performance of my AWs. 2 of my AWs are 14 months old and 4 are 10 months old. They have all been running .5 ohm builds. I was going to replace them after a year of use and retire them for flashlight use, but to be honest... even at their age they are superior to the Sony, Sammy, Subohm and LG.
The Aw 1600 runs just as long as the above 2500 mah cells, or at least they seem to. By the way, the Sony is the worst of them all, followed by the Subohm, the Lg and the Sammy.
Its gonna be AW from now on for this kid.
Thanks,
Geo
