We are pleased to offer this new advanced materials flight pack.  It uses our new True Spec Extreme Graphene V2 formulation which you can learn about here.  

We believe, for the most part, the flight pack consumer understands that C rates are pretty much useless and used to sell lower quality packs at a higher price.  True Spec Extreme Graphene V2 flight packs have true mAh and true factory C rate validated by SMCs own testing.  

Our FCR60 packs are equivalent to our competitors 60C to 200C packs but you may experience more voltage under load as our packs use advanced materials to lower the internal resistance of the cells.  These advanced materials will also increase cycle life.
