Q:What does the C rating mean?
A:The C rating is a measure of how long it takes a battery pack to discharge under a given load, expressed in fractions of an hour. As an example, a battery discharging at 1C would be empty in 1 hour, a 2C discharge would empty it in 1/2 an hour, and so on. For example: a 4000 Mah battery being discharged at 4000 ma, then it would be empty after an hour, and discharging at a rate of 1C.
