Lipo charging questions

[Big House]

I currently charge my lipos based on the mAh rating of the battery. What I mean by that is I set my charger (Hyperion 0606) to the charge rate of 5c. Now here is my question, should I base a full charge off the voltage I see through the balancer or should I be charging up to the mAh level indicated on the battery. The charger can display both.
