If the lipo label says 1C, charging at 2C+ may shorten life, especially if the lipo gets warm while charging at the higher rate. If the label says 2C or 5C, there may be a little life lost, but its going to be a small percentage, or at least if its a Hyperion lipo (less than 1%).
Some of the lipo manufacturers are now saying that their 1C rated lipos have been 2C all along, so it may not be a huge deal anyway. Still I tend to play it safe with lipo and honor the label's advice.
No, the only reason for higher C charging is to cut charge time.
