Trinity has just realased a 7-cell stick (flat) pack that is designed with Traxxas vehicles in mind, or other cars that don’t accept a “hump-style” 7-cell configuration. What does the extra cell do for you? Well the added voltage will give your car or truck added punch and speed, for ultimate backyard bashing. The cells are Intellect IB4600’s, which are known for excellent capacity and long-term durability. These assembled packs are available with either a Tamiya or Traxxas-style plug.
