Sorry for hijacking this thread mate.

This is the first time I'm using LiFe battery. How do you guys charge a LiFe battery? seems that when i plugged them on the charger, it would not accept 2s and I'll get that Low Voltage Error message. My LiFe battery is marked as 2s (6.6v). But when i switch my charger to 3s (9.9v) it works!
