I feel like I should add something.......
I'm not sure you need a lot of graphene to make it better, it might be application, not quantity, but that's not the point
I really don't care what they call it or why they say it is a better chemistry, I just know it is a newer chemistry and it does perform better, I was skeptical, but the discharge curve is just so much flatter, I don't care if they put unicorn fur in there, it is a slightly better battery
Now whether or not racer X needs them or not is a whole different question, but if they are in your budget, get some good ones, Motiv, Reedy, a big name, I haven't seen good matching on bargain new chemistry, but it does still beat one gen old bargain chemistry still
