That sounds a little odd to me as 11.1v is the nominal voltage of the 3 cell lipo pack. I run an HT Batteries lipo in my M11. Usually, it charges up to 12.5v and hangs around 12.1 for a while, but it's dropped down to 10.3 or so before I've charged it.

True, though.... you don't want to go below 3v/cell or you could risk damaging the battery. Oh, and make sure you charge the pack outside of the radio!
