Race Formula Extreme
"Race Formula Extreme" represents the latest in high performance Lipo technology. These pack have low IR which makes for a very strong voltage curve under discharge. These are high performance packs which use maximum thickness cells which have a very active formulation. This means it's possible for the case to get rounded with use as Lithium pouch cells have natural expansion and since the cells are maxed out they can push against the case. In our testing these packs offer more power/performance than the new genearation high mAh style packs being offered by some of our competitors.
