The C-rate represents the rate at which level the battery is providing energy. The higher power with a higher discharge rate (C-rate). 1C means that the battery is fully charged and discharged within one hour, 2C is 30 minutes, and so on 10C=6mins, 100C=6 seconds.

What does 100c mean 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 does 30C discharge mean?
C is also the discharge time at max current. 20C is 60/20 or 3.0 minutes. 30C is 60/30 or 2.0 minutes.
IS 100c battery good?
A more powerful battery (bigger C) is NEVER a problem. Theoretically a 100C 5000mAh battery could supply 500 Amps (100*5A), which is nonsense and would probably melt/ignite something very quickly. So the C ratings are mostly a lie, but still used to compare batteries… Anyway, more C is more better!
What is A discharge rate?
The discharge rate is defined as the steady current in amperes (A) that can be taken from a battery of defined capacity (Ah) over a defined period (h). Batteries for CEGB power stations are normally specified for a 10-hour rate.
Is a higher C rating better?
A higher C rating is usually achieved by having a lower internal cell resistance, so there could be some help in peak current, for a given load, but the difference will be small, and this is not a guarantee either as some low C rated cells actually have very low internal resistance, but can’t take the heat while some
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!
What is 2C discharge rate?
It is defined as the discharge current divided by the theoretical current draw under which the battery would deliver its nominal rated capacity in one hour. [29] A 1C discharge rate would deliver the battery’s rated capacity in 1 hour. A 2C discharge rate means it will discharge twice as fast (30 minutes).
What does 50 C on a battery 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.
What is the difference between a 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.
How is Lipo charge calculated?
To determine this number, take the mAh rating of your pack and divide it by 1000. If your batteries allow for a higher charge rate (1C-5C is the general range) simply take the numbers you came to calculating your 1C rate and multiply it by that factor.
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 A high rate discharge test?
The High Rate Discharge Tester are useful for assessing the performance of batteries used in automotive, traction, and other transient duty applications.
What does high discharge rate mean?
What is high Rate discharge battery? The high rate is representative of the charge and discharge capability of the lithium-ion polymer battery with respect to the ordinary rate.Normally high discharge rate batteries can be fast charged.
What does 80 percent depth of discharge mean?
For example, if the manufacturer of a 10 kWh battery recommends a maximum DoD of 80 percent, you shouldn’t use more than 8 kWh from the battery without recharging. You can see why DoD is an important factor to consider: a higher DoD means you can use more of the energy being stored in your battery.
What is the difference between a 25C and 35C LiPo?
The 25C batteries will only be able to supply ~70% of the current as the original 35C. This means less power available and also less time before voltage sag is to great to fly. It has nothing to do with capacity but even still, expect reduced effective flight times.
Is a higher C rating better on a LiPo battery?
Performance Benefit of Higher C rating
Having a higher C rated battery allows the battery to have a lower voltage drop under load. When the battery is able to maintain higher overall voltages, it is expected that the current increases as well.
How do I choose a LiPo C rating?
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 20C mean in battery?
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) 20C battery can in 5 minutes (60min / 20C = 5min)
What is the C rating?
The C Rating is defined by the rate of time it takes to charge or discharge a 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.
What does 10C discharge rate mean?
So what does “C” mean? The “C” in 10C represents the discharge rate, and 10 is the rate, which is 10 times the charge and discharge rate. 10C means that the maximum discharge current of the battery is 10 times the capacity. For example, for a 2000mah battery marked 10C, the maximum discharge current is 10*2000ma=20A.
