Vampire Racing’s popular and long lasting Lithium-Ferrite receiver battery packs are now available in a new 2014 edition. Coming in industry standard “straight” or “hump” pack dimensions, the 2S packs with a voltage of 6.6V allow the direct use with standard voltage receivers and servos without the need for a voltage regulator as 7.4V LiPo packs do. The straight pack makes use of 1600mAh cells while the hump pack comes built from high capacity 1900mAh cells. Both packs are pre-wired with XH balancer connectors and a JR/Futaba compatible universal plug.
