Sorry fo the slow reply - been out of town a lot lately for the holidays. Yes I have done some comparisons. I'll post some more plots this weekend. BTW, my GFX seems to be a little stingy on the capacity rating. It's giving me about 4400 mah on these but also gives about 4400 mah on a brand new EP4600 pack that just came of the matchers.

I'll try to get some more data posted this weekend.
