GT500 A123 Charge V / Cell

Have searched the forums but cannot find the answer to this. I just received a GT500 Duo charger and was setting it up to charge my LiFePO4 battery packs - all 2 cell packs / 2500 mah.

When you set up the parameters for LiFePO4 the default Charge V / Cell is 3.65 V. I am used to charging my packs to 7.20 V at full. Was wondering if the default setting in the GT500 is on purpose or perhaps based on their charging methodology / algorithm.

I did change to 3.6 V / cell and hooked it up to a pack that was about 3/4 charged. It topped out as done at 7.14 V and I noticed the cells were slightly different, maybe 3.6 for one and 3.45 for the other. At that point I had not changed the settings to mandatory balance so that likely would account for the pack topping out as done at 7.14

My question is really the 3.65 Charge V / cell. Since that is the default should I just set it back to that or change it to 3.6 V ?

I cannot see an answer in the GT500 manual that I downloaded. I also sent a message to support at Revolectrix and got a response that someone in tech support would answer. But that was 24 hours ago. No response yet. likely due to the weekend.
