Nothing special about the first charge so far as I know. I have heard that you want to go extra easy on the amp draw the first 3 cycles till the battery "fully cycles". I have also heard quite a few guys go with the 4.1v charge/ 3.2v discharge limits, just to further protect their investment.
Hope it helps (also hope some of the guys with high dollar lipo's chime in).
If I could only draw what I see in my head, then afford to build it, and finaly get to play with it...
