Lipo cell count and charger

[Tazz]

I just want to make sure I have this correct before I buy. A lipo battery 3s2p
would have a total of 6 cells, is this correct? If so I would need a charger that would be capable of charging at least 6 cells. If the charger was able to do 12 cells or more would I be able to charge 2 battery packs at the same time and if so would the 2 packs need to be connected in serial or parallel?

If this is possible what chargers are capable of doing at least 12 lipo cells?
