the amperage sounds about right, i've got a choice of 1 or 1.5 on the 959 charger. but i just read an article yesterday (i wish i could remember where) that said 10Mv per cell or 50Mv whichever is lower.
i guess what i should be asking is where is your pack(or any ones) peaking at? mine is in the low 7volt range, and this seemed a bit high but i have no experience with this pack or charger so i'm kind of in the dark.
