New Traxxas Power Cell Battery Packs

Traxxas Series 3 Power Cells are a good balance of price and run time. They have a 7-cell 8.4v hump pack that will fit in most Traxxas Models (except E-Maxx and E-Revo). The extra cell will get you about 5mph more, which is pretty good for just changing out your batter pack and you are not looking to make the jump to LiPo.
