If you are charging your battery to 11.1 volts then you are not overcharging it. You can safely charge each cell up to 4.2 volts. So 3x4.2 is 12.6 volts. Your problem might be that your not charging them enough wich makes you think they a not holding their charge for very long.

Also before charging them check the balance in each cell if one is to low that could indicate bad cell. Don't forget to check the balance ounce they are charged also.

With your charger you can monitor wats going on as the battery is charging and see how each cell is reacting.

Whats the ''C'' rating of your battery?

Increase the charging amps. The IMAX smart charet will stop charging and say full on the screen. If they're just stopping after 2 hours and it doesn't say full. Your never fully charging them

The rating for my battery is a 15 C. I can go up to 5 amps so what would a good charging amp be?

I think he means 11.1v is just what shows up on the display
My iMax will ask me to verify the cell count before it starts charging too (displays 3S 11.1v)
Also should be noted, once the battery is AT 12.6v, it's only actually ~70% full. It has to stay at 12.6 for a while longer before it's done charging
I usually charge packs at 1C, but apparently nano techs can handle charging up to 5C
