Nice link on Lipo usage A-Z

[electric]

This is probably the best write up on dealing with Lipo's I have seen in awhile. Covers everything from A-Z. in a easily undertandable way. Just start at the top and read all the way down. The cover "C" ratings, capacity (MAH), Charging, Storage, Connectors(not the 5.5's though), safety, voltage, balancing, just about everything.
