Hyperion 0610i Charger power supply

question about charging with the hyperion 0610i
1st do most people use the auto charge i charged my 7s gp3300s on automatic and when it was done they would burn the skin.
2nd is there a way to tell how much MAH is in a batt without going through the charge. just to check?

other than that this charger is sick compared to my old gws mc2002
thanks for the ps confirmation it seems pretty good so far
just waiting on my 5s1p zippy H before i test it on lipos hurray i made the leap
peace
