hi guys, i was just wondering if i could just use one battery with the evx-2. ive never had one or even used one so no experiance there. im asuming it would be prety sluggish compared to 2 packs if it even works on 1. if it dosent work on one, could i just steal the blue xl-5 outa my slash and put that in there so i could run one battery instead? ...i know you guys are probly wondering "why only run one battery!" ..well batteries, chargers, and summit are alot of money for 14 year old so, will it work? oh yah, and can you run different batt capacities? like run a 4200 and 5000? would that effect it? asuming so but i would love to know!
