You are correct that 1C for your battery is 1.3 amps. For setting your charger at 1C, simply use the battery rating in AMPS. Battery voltage or number of cells does not figure into the C rating here.
The iCharger rep was also correct. You "could" charge your batteries at up to 8 amps, but that is a rating of your charger and power supply. That doesn't mean your battery is capable of that charge rate.
8 amps would be just over 6 C for your pack. Some lipos can be charged at up to 10C. Depends on your particular battery. Best to read any paperwork (or label on battery) for the MAXIMUM charge rate.
You can't go wrong at 1C....you can shorten your battery life considerably, or worse, by charging at too high a charge rate.
Hope this answers your concerns.
