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).
Greater capacity than typical sport packs for more “punch,” and longer run times
Heavy-duty construction to withstand high-current output
Built with Traxxas High-Current Connectors for the most reliable and efficient power transfer
12-gauge wires with flexible silicone insulation resist damage and allow easy installation
Premium-quality high-capacity, high-voltage, low-resistance cells deliver maximum run time and ‘punch’
Optimized for maximum performance in Traxxas models
Much more power than 7 cell, must use adapter kits for hold down
Nice speed increase and runtime compared to my last set of 7.2v 3000 mah batteries.
