The Dynamite® High Voltage Reaction® 50C LiPo cells allow these packs to carry a higher overall voltage per cell (4.35V vs 4.2V) which translates into faster and longer run times than regular LiPo packs. These are the perfect batteries for the basher that is looking for more wheelie popping power! Excellent for 1/10 to 1/6 vehicles and boats.
