The maximum possible capacity in a Power Cell NiMH pack! Experience the longest run times and highest sustained voltage under load. Ideal for peak performance in power-hungry models such as the brushless-equipped Rustler VXL, Bandit VXL, Stampede VXL, E-Maxx Brushless Edition, and E-Revo Brushless Edition. Traxxas Series 5 Power Cell batteries feature the latest 5000mah NiMH cells and are available in 7-cell "hump" and flat configurations to fit all Traxxas 1/10 scale electric models. New 8-cell packs are also available for an incredible 9.6v power boost!
For proper fitment, Series 5 8-cell batteries require an optional Expansion Kit (TRA3725X for Rustler, Bandit, and Stampede; TRA6727X for Stampede 4X4; TRA5827X for Slash and Slash 4X4).

No complaints. Haven't used to long but works well so far
With my Slash 4x4 in trainer mode I get almost 30 minutes of run time. Very happy with purchase!!
