I just got this 6 cell 1100mAh pack but i'm not sure what i should charge it at. On the individual cells it has 2/3A, 1100mAh, 1.2V with a standard charge rate of 14-15hrs @ 110mA.

The charger i will be using has two outputs: 1-4 cells 3A/1.5A
4-8 CELLS 1.5/1A

I know i have to use the 4-8 cell option but not sure at what amperage. Any help would be great.
