lipo charger readings?

[Aaran]

hey guys got my first set of ipo and a overander lipo charger.

i set my charger up for 4.6amp charge (my ces are those new orion acarbon 7.4v 4600mah with 45c discharge)

set the charger to 7.4 vots (2s) and et it run. but the votage reading on the dispay shows the battery pack running over 7.4volts (starts at 6 ish volts then runs up sowy and does not stop at 7.4, it keeps cimbing)

is this normal for this sort of charger?
