sorry for the delay, wanted to get this right so asked trakpower direct
3200 seems like 4200 due to the way the cell works, because they sustain a higher voltage under load, (the science bit) the watt hours are higher than a nimh pack, this in turn reduces amps for the same output giving the cell a better ability to deliver thier capacity more efficiently, hence the packs dont get hot loosing efficincey and the 3200 lasts longer in run time
next
low voltage causes a chemical reaction in the pack this turns to heat, gases are created and fire can occur. this occurs under 3volts per cell
i presume when the packs are made there is a residual voltage in them from the chemistry
capacity is measured on a lipo FROM the cell being at 3 volts so a cell is at 3 volts, its charged then that will give you its capacity
by discgharging below this at high current draw will result in swollen/damaged packs. if you have left the pack plugged in over night and the draw is only low, the cell can still be damaged, but it is possible in some cases to recover the pack, i can unoficially tell you how when i have more time, its not the done thing but it can be done under close scruitiny
hope that helps a bit, any more questions and ill do my best to get you correct answers!
