What does the C mean on a battery?

The battery C Rating is the measurement of current in which a battery is charged and discharged at. The capacity of a battery is generally rated and labelled at the 1C Rate (1C current), this means a fully charged battery with a capacity of 10Ah should be able to provide 10 Amps for one hour.

Is higher or lower C rating on battery better?

The short answer is that when it comes to flight times and motor performance, the higher a battery’s C rating, the more likely it will make you smile. A 45C pack makes a joke of a 10C pack when it comes to power delivery. A battery that has a higher C rating delivers more energy, and that means higher performance.

How many C battery do I need?

It is also important to consider C-rating when charging batteries. I always stick to the rule of thumb that you should charge your batteries at no more than 1C even if they are rated for a higher Charge c-rating.

What does 6C mean in batteries?

The C rating number is the number of times the battery can discharge in one hour without overheating or damaging the battery. For example, a battery with 1C can discharge it’s entire capacity in 1 hour, while; 6C battery can in 10 minutes (60min / 6C = 10min)

What size are C batteries?

C-sized batteries are smaller than D batteries but larger than AA and AAA batteries. They are: 50mm or 1.97 inches in length. 26.2mm or 1.03 inches in diameter.

How does C rate affect the cell life?

At higher current(C) rates, although the overpotential is high and the corresponding internal resistance might seem to increase, the cell temperature would rise at such higher C rates which will eventually lead to decrease in internal resistance.

What does 20C lipo mean?

The C rating is the maximum, safe, continuous discharge rate of a pack as specified by the manufacturer, so when you see 20C printed on your label, it means it can be discharged at 20 times the pack’s capacity,”continuously”. Capacity is usually measured in mAh and a popular cell size is 2200mAh.

How many amps is 2C charge rate?

It is the amp hour of the battery packs. While most are familiar with the milliamps, the amp hour is that number divided by 1000. So for a 5000mAh battery, 1C would be 1(5) or a 5 amp rate, 2C would be 2(5) or a 10 amp rate, and 5C would be a 25 amp rate. A 1C charge or discharge should be an hour long process.

What’s the difference between 50C and 100c lipo battery?

a 50c lipo has a continuous 50c rating with a 100c burst. a 100c lipo has a continuous 100c and 200c burst. So buy a 100c lipo for more punch!
