How many amps can I charge my 4S lipo?

How many amps can I charge my 4S lipo?

Using the formula, 100 watts divided by 14.8V equals 6.75 amps, which is the maximum current the charger will be able to deliver for a 4S battery.

Is it safe to charge a LiPo at 2C?

But times have changed and lipos have changed and chargers have changed so YES by all means charge at 2C. No harm will come from it and if you don’t believe me, feel free to read the 1000s of prior posts regarding the subject. I charge all my batteries at 2C when in the field, 1C at home.

What does C rating 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. That’s the same capacity and twice the amp draw.

How is charge rate calculated?

The discharge rate when discharging the battery in 10 hours is found by dividing the capacity by the time. Therefore, C/10 is the charge rate. For example, a battery capacity of 500 Ah that is theoretically discharged to its cut-off voltage in 20 hours will have a discharge rate of 500 Ah/20 h = 25 A.

What is a 5C charge rate?

Charge rates are just what they sound like. It is the amp rate at which you are capable of charging a specific battery pack. 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.

What does 1C charge rate mean?

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.

How many volts is a 4S Lipo?

Battery Voltage and Cell Count (S) Each cell in a standard LiPo battery has a nominal voltage of 3.7V. Therefore battery voltage is often referred to as how many cells in the battery (aka “S”). For example, we call a 14.8V battery a “4-cell” or “4S” battery.

How long should lipo take to charge?

On average, an RC LiPo battery will take 30 minutes to an hour to charge. Depending upon the size of the battery and the size of the charger you are using to charge the battery, will depend upon how long the RC LiPo battery takes to charge.

How long can you leave Lipo batteries fully charged?

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.

What does 2C mean in battery?

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.

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 Max discharge 2C mean?

C in this context means the battery capacity in Ampere-Hours but divided by hours. If battery’s capacity is 3.4 Ah, then C would be 3.4A, and 2C would be 6.8. “C” is the ampere-hour rating of the battery. This would mean 2C discharge rating for the battery is 6.8 Amp, the battery would be rated at 3.4 Ampere-hours.

What is 0.2C discharge?

Generally, the discharge rate of mobile phone batteries is 0.2C, if the battery is 5,000mAh (5Ah), the discharge current is 0.2C*5Ah=1Ah, that means the battery be discharged 1,000mAh per hour and could operate around 5 hours.

How long does it take to charge a lipo at 1C?

At a 1c charge rate a lipo will take approximately 1 hour to charge. So a 5000mah pack at 5 amps will take 1 hour.

What Lipo 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 25C mean on Lipo battery?

Yes, they can, one of the reasons for respect when using them. 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. – Neil_UK.

What is charge rate?

noun. : a rate based upon the amount (as of electricity) used by a customer and upon his maximum demand.

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 does 5C discharge mean?

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.

Can I charge Lipo at 5C?

If your battery can be charged at 5c and it’s a 5000mah battery, it can be charged at 25amps. The battery can be charged at the 6amps with no problem. If your battery can be charged at 5c and it’s a 5000mah battery, it can be charged at 25amps.
