This is a Power Cell 4S 6700mAh LiPo battery with ID technology from Traxxas. Traxxas is taking battery power to new heights with brand new 4-cell LiPo batteries! With a 6700mAh capacity and 50C burst discharge rates, you'll be able to deliver the power, performance, and runtime that your vehicle deserves. Clocking in at over 30 volts in 8S configurations, the Traxxas 4-cell LiPos will stand an X-Maxx up on its wheelie bar and help it catch massive air as soon as you touch the throttle. These batteries are built using the same sturdy construction methods as the Traxxas 2-cell and 3-cell batteries.
Charger compatible with Traxxas High Current Connectors (4S) with iD and LiPo balance wires (i.e. TRA2971 Traxxas EZ-Peak Live 12-Amp Charger).
