What is C in 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 does 80 C mean on a LiPo battery?

For example, a 1300mAh 80C battery can theoretically provide 1.3Ah * 80C = 104A. This means that both the capacity of the battery, and the C-rating contribute to the maximum current a battery can draw in continuous supply.

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.

Is Higher C in battery better?

Conclusion. A higher C rated battery in the vast majority of setups will be best suited. Not only does a higher C rating provide better performance but it also provides higher reliability for ESC's.

What does 50C LiPo mean?

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.

LiPo Battery C Rating Explained

What C rating do I need?

Having the battery pack with the highest C rating is always best for the power system and battery pack health. It is best to have a discharge rate overhead of 30%. If you work out a maximum power system discharge of 100 amps. Your battery pack should should deliver at least 30% more or 130 total amps.

What does 35C battery mean?

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 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.

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.

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 is 30C battery?

The higher the C rating, the higher the cells are capable of discharging. For example, a 20C 2100 mah lipo can discharge at 42 amps (cell count does not matter), and a 30c 2100 mah can discharge at 63 amps.

What does 30C LiPo mean?

For example, a 2200 mAh lipo pack with a 30C rating is supposed to be able to support 2200mAh (or 2.2Ah) X 30 load which is 66 amps. 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".

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 the difference between 50c and 25C LiPo batteries?

While the 25C pack will supply enough amps to run a 10.5 safely the difference comes in the fact that higher C rated batteries have a lower IR which is a key part to them getting the higher C rating. If you have run matched NIMH packs in the past you know how important IR was. Same thing applies with lipos really.

How do you charge a LiPo battery?

The safest way to charge a lipo battery and the one that puts the least amount of strain on your battery is to charge at a rate of "1C" or 1 times capacity. A 1C charge rate means that the current will charge the entire battery in 1 hour ( assuming you are starting with a fully discharged battery around 3.2v ).

How does LiPo battery work?

Working principle

Just as with other lithium-ion cells, LiPos work on the principle of intercalation and de-intercalation of lithium ions from a positive electrode material and a negative electrode material, with the liquid electrolyte providing a conductive medium.

What is C in lithium ion?

The high-rate battery is divided into a discharge rate and a charge rate, and “C” is used to indicate the ratio of the charge and discharge current of the battery, that is the rate. For example, a 1200 mAh battery, 0.2 C means 240 mA (0.2 mA of the 1200… Battery. 3 min read. Read more from Battery Lab.

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.

What is C-rate in charging?

The C-rate is the unit battery experts use to measure the speed at which a battery is fully charged or discharged. For example, charging at a C-rate of 1C means that the battery is charged from 0-100% in one hour.

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 is 20C LiPo?

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.
