lipo charging/breakin?

[rootar]

I keep my 5000mah 3s maxamps pack fully charged when i put it up, for no longer than a week or so and then i use it and then charge it back up before i put it up agian, is there anything wrong with that? should i pull it off the charger at 3.4, 3.8, or 3.7 volts per cell which would be best? the max amount of time it sits before i use it again is a week (usally only 3-4 days).
