C is the dischare or charge rate.
1C =1xstored energy
aka if you have a 5000mah battery
1c (you usually charge rate) = 1x5000mA =5A
or 20C (battery discharge rate) =20x5000mA = 100A
Most batteries will post multiple C numbers for discharge: the most common is the continous, but they may also post a peak or burst or susutained or whatever other word they feel like using. But Continuous is the number you would care about most of the time.
is it possible to talk to any of you guys on MSN messenger about lipo batterys? as i have been looking around and im now very confused and have lots of questions which would take a lot of forum posting
