What does the C mean in RC batteries?

The C rating defines the MAXIMUM CURRENT you can draw from the battery and it is a multiple of the mA-Hr rating. So a 5000 mA-Hr battery with a 10C rating can deliver 50,000 mA or 50 Amps. At that rate, the battery would fully discharge in 60/10=6 minutes.

What does 25C mean on LiPo battery?

Don't think that your battery can deliver 130A for 1/25th of an hour = 2.4 minutes, the capacity drops as the discharge rate increases. That 25C rating is what it can deliver, and without damaging itself.

How much C rating do I need?

Determining how much C rating you need

If you don't want to read too much into the details, here's the short answer: For more power and current delivery – especially on a miniquad – stick to a higher C rating battery, at least 60 or above for the continuous rating.

What does C mean in lithium batteries?

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.

What does C Rating mean on a Lipo Battery



What is 1C 2C 3c battery?

Discharge rates of a battery are governed by C-rates. The capacity of a battery is commonly rated at 1C, meaning that a fully charged battery rated at 1Ah should provide 1A for one hour. The same battery discharging at 0.5C should provide 500mA for two hours, and at 2C it delivers 2A for 30 minutes.

What is 10C battery?

A 1000mAh LiPo battery, the burst rate is 10C, which means the battery can provide 10 x 1000mA=30000mA current for several seconds.

What does 50C mean on LiPo battery?

50C = 50 x Capacity (in Amps) Calculating the C-Rating of our example battery: 50 x 5 = 250A. The resulting number is the maximum sustained load you can safely put on the battery. Going higher than that will result in, at best, the degradation of the battery at a faster than normal pace.

What is C value of a battery?

A C-rate is a measure of the rate at which a battery is discharged relative to its maximum capacity. A 1C rate means that the discharge current will discharge the entire battery in 1 hour. For a battery with a capacity of 100 Amp-hrs, this equates to a discharge current of 100 Amps.

What is the highest C rating for a LiPo battery?

A C rating is a value given to the LiPo battery pack that refers to the maximum discharge rate of the LiPo. Examples of C ratings could be anything between 30C to 65C. Numbers outside of this range are possible as well.

Is a lower C rating better?

In fact the higher the C rating, the better off your entire system will be. Here is a quick review of how we use the C rating to calculate the maximum continuous discharge current the battery can output.

Is a higher C rating better on a LiPo battery?

The C rating for a LiPo battery, quite simply, refers to the capacity of energy the battery can safely discharge, represented as a multiple of its overall capacity. A battery that has a higher C rating delivers more energy, and that means higher performance.

What is the difference between 30C and 50C LiPo?

The 50C battery would be capable of delivering more current than 30C one, if needed. However, if nothing else in your power system has changed, it will draw the same current as before. You have some extra current capability, which you are not using, so you will not see any difference in flying or charging times.

What does 30C battery mean?

Note, running at 30C means that the battery will not last for long! Capacity is rated in mAh or Ah and the "h" part means "hour". there are 60 minutes is an hour and 60 / 30 (the 30 is running a lipo at 30C) = 2 minutes.

What does 0.1C mean?

C values are relative measures of power: 2 C is twice the power of 1 C, and 0.1 C is one-tenth the power of 1 C. High C values represent higher power, faster charging and discharging, and more stress on the battery.

Which is better C10 or C20 battery?

C10 rating is known to be FAST DISCHARGE whereas a C20 rating is attributed as MEDIUM DISCHARGE. C10 rated batteries are always recommended for solar and industrial purposes with the best charging and discharging rates. As the high load uses battery power, it is capable of delivering more energy in a short time.

What does 2C charge rate mean?

C-rates are the rate of discharge (or charge) as compared to the capacity of the battery. A 1C discharge will be the current that would seemingly go through the rated ampere-hours of the battery in an hour. A 2C rate is twice that current. A 0.5C rate is half that current.

What does 15c mean on a LiPo battery?

That simply means that we're charging it at 1x or 2x its mAh capacity, so for your 130mAh battery a 1C charge rate would be 130mA, and it would take about 1 hour. For LiPos, you generally shouldn't charge at any more than 1C rate unless the packs specifically say you can.

What is 10C 20C battery?

10C, means maximum continous discharge at 10 times the battery's capacity. if that battery is 10C, it means that you can discharge it at 10 times it capacity, which is 2.2 amp hours. 10C times 2.2 amp hour=22amps. so, a 20C, 2200 milli-amp-hour (or 2.2 amp hour) battery can be discharged at 44amps.

What does 20C mean on a battery?

The 'C' in C rating stands for Capacity. 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".

What is 5C battery?

High Discharge Rate Lithium Polymer Battery 5C

The High discharge rate lithium Ion battery 5C can continuous discharge at 5C. It means if the capacity is 1000mAh, the discharge current is 5*1000mA=5000mA. Thus, if you use a higher capacity battery, the discharge current is very big.
