True Spec DV Extreme 11.1V-5200mAh-135C pack.

This pack is the lowest priced 5200mAh pack on the market using 100% Lithium Cobalt Oxide(LCO) in combination with advanced materials to increase the power/performance.  You will not find another pack in this price range with this much power/performance.  Packs at a similar price typically use a blend of LCO and LicoMnNio2 which is a cheaper material.   This lowers the cost of the packs but also decreases the performance.  One way to tell if a pack doesn't use 100% LCO is to check the weight.  Packs with 100% LCO will typically have a higher weight.
