lipos dont need discharging and if you let them drop below 3v per cell it can knacker them.
ALWAYS charge the lipo on your chargers lipo mode set it to 1C and set the mah to the capacity of the charger e.g a 4300mah lipo should be charged at 1C 4300 mah the charger will have a CC CV ( constant curent constant voltage) function for lipo which automaticly charges the pack up to a set voltage of 8.4v then varies the charge current to keep the charge voltage at this level, as the pack is charged so the curent reduces keeping the voltage stable.
lipos can be balanced but ONLY using a special lipo balancer and they dont need doing anywhere as often as nimh or nicad packs.
if your speedo has one turn on the lipo cut off if it dosent get a lipo cut off ( these prevent you acidently draining the pack below 6v and damaging it)
if you want to get a lipo charge sack and charge the pack in that although opinion is devided on these.
if you have a brca aproved pack
see here:

( please note this is a rolling list and it may not have been updated to include your pack yet)
then drop dead short and overcharge tests have been caried out on that pack and the results have only been venting or expansion within the solid case.
Lipo's are great you can do an entire days racing on one pack just topping up ( I've done this numerous times) they dont seem to get hot like nimhs do ( max charging temp I've had was 26degc in a lipo sack)
