You have to divide your LiPo pack capacity (mAh) by 1000 in order to convert from mA to A. This results in 5000mAh/1000 = 5 Ah. Therefore, 1C charge rate for battery with 5000mAh is 5A. And a 2C charge rate would be of this double or 10 A.

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 does 2C charge rate mean?
The C Rate charge or discharge time changes in relation to the rating. 1C is equal to 60 minutes, 0.5C to 120 minutes and a 2C rating is equal to 30 minutes.
What is a 5C 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. A 1C charge or discharge should be an hour long process. 2C cuts that time to about 30 minutes.
How do you calculate charging time?
How to calculate charging time yourself?
- Divide the load power by 1,000 for a value in kilowatts.
- Divide the power of your battery (also in kW) by the figure obtained to get the charging time.
- First calculate your load power (P), by multiplying the voltage (U in volts) by the current (I, in amps).
How is DOD calculated?
Depth of discharge is normally expressed as a percentage. For, example, if a 100 A h battery is discharged for 20 minutes at a current of 50 A, the depth of discharge is 50 * 20 / 60 / 100 = 16.7 %.
What is C rating on LiPo?
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.
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:
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 is 1C LiPo charge rate?
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 0.5 C charge rate?
A C-rate of 1C is also known as a one-hour discharge; 0.5C or C/2 is a two-hour discharge and 0.2C or C/5 is a 5-hour discharge. Some high-performance batteries can be charged and discharged above 1C with moderate stress.
Can I charge LiPo at 2C?
If your 4800mAh pack is a two cell LiPo, you’ll need ≥ 81 watt charger to get your 9.6Amp setting 2C charging rate. If your 4800mAh pack is a four cell LiPo pack, you’ll need a charger with ≥ 162 watts of power to get hit that 2C charge rate amperage.
What is the charging current for 200ah battery?
30A
Charge methods: constant voltage. Charge: 77 F(25 C) cycle use 14.4-14.7V. Maximum charging current: 30A.
How long does a 5000mAh battery take to charge?
So, how long does it take to charge an 800-5000mAh NiMH battery?
How Long to Fast-Charge NiMH RC Batteries.
| Battery Capacity | Output Capacity | Charge Time |
|---|---|---|
| 4200mAh | 600mAh | 8.4 hours |
| 5000mAh | 600mAh | 10 hours |
How do I calculate current?
The current is the ratio of the potential difference and the resistance. It is represented as (I). The current formula is given as I = V/R. The SI unit of current is Ampere (Amp).
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 DoD in inverter?
DOD, also known as “Depth of Discharge” is used to describe how deeply the battery is discharged or should be discharged.
What is 0.1C load?
At 1C, the battery charges and discharges at a current that is par with the marked Ah rating; at 0.5C the current is half, and at 0.1C it is one tenth. On charge, 1C charges a good battery in about one hour; 0.5C takes 2 hours and 0.1C 10 to 14 hours.
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 30C lipo mean?
20C is 60/20 or 3.0 minutes. 30C is 60/30 or 2.0 minutes. If your flights at 100% throttle are always longer than 3 minutes than a 20C battery is plenty. This is just another way to see what battery you really need.
What’s better 2S or 3S lipo?
On a 2S LiPo battery, that motor will spin around 25,900 RPM. On a 3S, it will spin a whopping 38,850 RPM. So the more voltage you have, the faster you’re going to go.
