Just so people don't get confused, we generally use three charge rates. Fast charging (usually 1 to 3 C or 1 to 3 times the pack capacity), C/10 (one tenth the capacity of the pack, like the chargers that come with radios. Usually 50 to 60 mAh.), and "TRICKLE" charge (C/100, or usually 5 to 6 mAH).

Too many people are calling the overnight chargers "trickle" chargers. They're not, and we're going to start confusing new guys. Like all the advice telling beginners that it's fine to leave they're packs on "trickle" charge continuously. Which it is, but if they think C/10 is trickle, they can ruin their packs.
