Thanks for the help. After reading up a bit more, I think I am going to keep my eyes open for gently used Ice charger. I may actually even be able to make runtime with my current batts if I can get them cycled and charged to their full potential. I am just learning, so I certainly dont need top shelf batts until I can make it around the track without dinging the wall. My charger kept false peaking and having trouble, so we'll see how the packs do with a Good charger.
