Reedy's WolfPack LiPo batteries have been a huge success thanks to  their race-level quality, affordable price point, and wide variety  of configurations. Now Reedy is proud to release the next generation  of batteries that take the WolfPack philosophy to the next level.  Thanks to increased capacities and generous discharge capabilities,  overall power and top speeds are improved while extending run times  far beyond what is capable with NiMH batteries or lower-quality LiPo  batteries. Each WolfPack Gen. 2 battery features Reedy's molded hard  case for maximum crash protection in sizes that fit the most popular  car configurations. Wires now exit the case through a rubber gasket  which protects the wire's insulation while helping to prevent moisture  from entering the case. High-quality cell manufacturing and construction  techniques result in reliable operation and maximum cycle-life. Reedy's  WolfPack Gen. 2 LiPo batteries come equipped with beefy silicone  wires and a reliable, low-resistance High Power T Plug connector.  An integrated balancing harness with a XH connector is included.  Install the WolfPack today and let you your car howwwwl!
