Unhappy What does "20C" on battery stand for?

There is a Dymond Modelsport battery on which the label reads:
Receiver battery LIFE
2S1P
6.6V/2100aAh
20C
What does that "20C" mean?
Also: What does the word "LIFE" stand for?

Sure, ad more stuff

Now that there is a tricky idea! Just what the average modeler needs--more soldering--another failure point. Didn't anybody ever hear of the KISS princple?
