Glad to hear you got it updated successfully. I updated my 0610i to v1.6 a little while ago, but won't get to see what all changed until tomorrow night.

I'll go with tc3_racer on the max business, reading the "manual" it says lipo is limited to 100% on teh 0610i chargers. I'd stick with that until you find out it means something diff for the DUO.
