Now I'm having a hard time figuring this out. I presently run on 48V 34 amp SLAs. To get to close to the 48V mark with lipos, do I need to go with 12 or 13 cells? 3.7V nominal times 12 = 44.4V or 3.7V nominal times 13 = 48.1V. Which one is it? If 12 cells is the number I need it seems a lot easier to configure, I would need 12 6S 5000 mah packs total. I would probably try Turnigy packs at first (not the Nanotechs) as I don't think I can convince my wife of letting me spend almost $1700 for Hyperions. Turnigys 40C would be under $900 including shipping.
Man I am also having trouble wrapping my brain around the fact that I could get better power and range from just two battery modules with less than half of the volume and weight of my SLAs.

34AH SLA batteries would be a rough equivilent to 17AH in Lipos - Lead batterries are capacity rated at 20 hours discharge normally - they generally get about half their rated capacity when discharged at 1c. 13s would be a 48 volt Lipo setup. I would just go 12s or 14s myself.
My conversion yielded about 3/4 the volume, less than half the weight and 4 times the usable power vs the lead. I also gained slightly higher voltage and a HUGE difference in voltage under load(way more punch). The difference is huge.
