I need to construct a battery powered portable demo. I could design a charging circuit around the bq24070 from TI, but assembling a leadless QFN package by hand kinda scares me (and scares my technician friend even more). This seems like the sort of thing that a Batterys-backwards-R-Us or Sparkfun (hmmm... I should go check there!) might already have. Does anybody know of a supplier of Li-Ion battery packs complete with charging circuits, DC supply input, and either a regulated or unregulated output? Where might I find such a beast? --wpd
