My question is how does MaxAmps get these super high mAh batteries? They've got a 13,500mAh pack
http://www.maxamps.com/Lipo-13500XL-74-Pack.htm How come other battery companies don't have these super high mAh batteries? MaxAmps also has a 10,000mAh 4s, 5s and 6s packs. I'd love to have a 10,000mAh 4s pack for my MMM 2650 powered Slash 4x4, but at $399, no way I can justify it. But imagine the run time!
