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 ). For example, if you had a 1000mAh lipo, to charge at 1C you would set your charger for 1 Amp. If you had a 500mAh battery, you would set your charger to 0.5 Amps.

What is 1C charge rate?
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 rate should I charge my LiPo?
1C
For the vast majority of LiPos, the Charge Rate is 1C. The equation works the same way as the previous discharge rating, where 1000mAh = 1A. So, for a 3000mAh battery, we would want to charge at 3A, for a 5000mAh LiPo, we should set the charger at 5A, and for a 4500mAh pack, 4.5A is the correct charge rate.
What does 1C mean on LiPo batteries?
Charge and 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.
How do you calculate 1C charge?
If you are unsure of your batteries charge rate, it is safe to charge the pack at a 1C rate. To determine this number, take the mAh rating of your pack and divide it by 1000.
How is LiPo C rating calculated?
C Rating Calculation
- Calculate the amps times the c rating to get the total output current:
- This means that we can discharge 40 amps continuously without damaging the battery.
- Determine discharge rate by multiplying Amps x C Rating.
- Divide by number of motors:
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.
Is it OK to leave a LiPo battery charge overnight?
Never leave your LiPo batteries sitting around on a full charge for more than 2-3 days. If by the 3rd day you realize you are not going to use your battery today, you need to discharge your battery down to 3.6v-3.8v per cell for safe storage until you are ready to use the battery again.
How long does it take to charge a 5000mAh LiPo?
1C is usually a safe bet (5A for 5000mAh) if the battery manufacturer doesn’t specify a maximum charging rate. 1C means that it will take about 1 hour to charge the battery from flat to fully charged.
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
How many amps is 2C charge rate?
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.
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 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.
How do you calculate LiPo battery charge time?
In the ideal/theoretical case, the time would be t = capacity/current. If the capacity is given in amp-hours and current in amps, time will be in hours (charging or discharging). For example, 100 Ah battery delivering 1A, would last 100 hours. Or if delivering 100A, it would last 1 hour.
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.
What does 100C mean on LiPo battery?
1550mah 5s 100C: Max Current Draw = 1.55A x 100C=155A. 4500mah 6s 50C : Max Current Draw = 4.5A x 50C=225A. This means that we can discharge 155/230 amps continuously without damaging the battery. It may also be noted that increasing the C rating or increasing the battery capacity can increase Max Current Draw.
What is the highest C rating on 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 LiPo better than Li ion?
LiPos offers several performance enhancements compared with Li-ions, including higher energy density and lighter-weight batteries. In addition, LiPos can be produced in a wider variety of shapes and sizes. However, today’s LiPos use gelled membranes, not fully solid polymer electrolytes (SPEs).
What is the lifespan of a LiPo battery?
LiPo batteries is one area of the RC hobby that can be fairly expensive. Especially if all the RC vehicles that you prefer to run, uses a different pack. The typical lifespan that we can expect from a LiPo battery pack can on average about 2 to 3 years.
Do I need to discharge my LiPo batteries?
LiPo batteries also don’t develop memory or voltage depression characteristics like NiCd/NiHm batteries, and do not need to be discharged before being charged. But they’re not without their downside. Mishandling of these batteries can lead to fire, explosions and toxic smoke inhalation.
How much time does a 33W charger take to charge 5000mAh?
Big battery and 33W fast charging
The OPPO F19 packs a 5000mAh battery and supports up to 33W Flash Charge. The company claims that the bundled adapter can charge the phone completely in just 72 minutes.
