What is 1C for a battery?

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 is 1C charge rate in LiPo batteries?

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.

What is 10C in battery?

Burst Current High discharge LiPo battery is also given a C rate in terms of burst, which is the rate at which the battery discharges in a short period of time. 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 C5 in battery?

A C1 rating means that the rated discharge current will discharge the entire battery capacity in One hour. A C5 rate for this battery would be 150 Amps at a higher rate of discharge, and a C2 rate would be 150 Amps at an even higher rate of discharge current as shown in the example below.

What does it mean to charge battery at 1C?

It might as well mean 22A over 1 hour, or any other combination that multiplies to 22Ah. C is generally the capacity divided by 1 hour, so for your battery it would be 22A. Hence eg. ‘charge at 1C’ can be stated, independent from the capacity of a battery. The notation for C as documented in the standard IEC_61434 is presented by Equation

What does the C rate on a battery mean?

The c-rate is the governing measurement of what current a battery is charged or discharged at. For example, the posted mAh of the battery is the 1C rating. If a battery is labeled 2000mAh, then its 1C rating is 2000mAh. To make this simple, the battery should provide 1C current for one hour.

What’s the difference between 1C rate and E Rate?

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. A 5C rate for this battery would be 500 Amps, and a C/2 rate would be 50 Amps. Similarly, an E-rate describes the discharge power.

What’s the difference between charge at 1C and 22A?

Only if the manufacturer says so. It might as well mean 22A over 1 hour, or any other combination that multiplies to 22Ah. C is generally the capacity divided by 1 hour, so for your battery it would be 22A. Hence eg. ‘charge at 1C’ can be stated, independent from the capacity of a battery.
