Looking to purchase some aftermarket batteries and I'm lost when it comes to batteries. Does max amps make a good pack? I was looking to invest in these LiPo 9000XL 3-cell 11.1v XO-1. "These packs are the largest capacity and highest voltage packs available for the xo-1. By removing the lower part of the battery tray, these packs will fit perfectly and will lower the center of gravity on the xo-1. The 3s 9000XL packs will give you a 10%+ increase in voltage and top speed. The higher voltage will also allow you to get to top speed faster because of the increased voltage retention over the stock packs. The 9000mah gives you almost double the run time of the 5000mah packs. These packs will make your Traxxas XO-1 scream! If you're looking for an insane amount of power, these are the packs for you!"
