I found the graphene is like the regular batteries.
What type of application? In my user case I use them for my 260 quad, my FT Spit and the FT Storch.
I only own the "low end" 3000 15C 3S batteries. Compared to the 2200 35-70C 3S Nanotechs I gain about 25% more mAh and only 7,5% more weight and a much better discharge curve. Even when I have use the Graphene down 75-80% I still can do punch-outs and WOT without the voltage sagging. There is another thing that separates them, charging cycles. According to test @ rcgroups, they should survive about 1000 recharges @ more than 3C. But I don't fly that often so I might return with the results in about two years or so. I only have about 25 cycles on them so far. No puffing, no heat and a good quality build. Just like regular "cheap" LiPos? Not even close in my limited experience.
