### What is C rating Calculated

**C Rating** is a fairly misunderstood concept in batteries. The C Rating is defined by the rate of time it takes to charge or discharge a battery. You can increase or decrease the rate which in turn will have an inverse effect on the time it takes to charge or discharge the battery. An example of this is if a battery amperage is 2000mAh or 2Ah and has a 1C rate, then it will take 60mins to charge or discharge the battery. 1C rating is the base time which is always equivalent to 1 hour or 60mins.

The C Rating's charge or discharge time changes proportionally to the rating. 1C is equal to 60mins, 2C is equivalent to 0.5h or 30mins and a 0.5C rating is equivalent to 2h or 120mins. The equation is simple.

**t = 1/Cr** to view in hours or to view in minutes use

**time = 60mins / Cr (c rating)**
In fact this is quite simple

However, I think we all want a battery that charges very quickly but discharge slowing to make it last no?

From the specs above. this would mean if I am correct

that at standard charging method it will take 2 hours to charge the battery and that it could take 30min to charge at max discharge but that is a pulse of 30sec. In coutniuous discharge, it will be 1h to discharge it.

Since the battery is 5.12kWh and it can be discharged at Max continuous discharging current at 1C so 1h, this means I can get 5.12kW of continuous power during 1h. If that is correct, this is the best I have seen so far.
