What C rating do I need for my LiPo battery? ›

The C Rating You Need:

The safest way to charge a lipo battery and the one that puts the least amount of strain on your battery is to charge at a rate of "1C" or 1 times capacity. 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 ).

The C rating is a multiplier that dictates discharge. You can figure out the maximum theoretical discharge by multiplying the C rating by the capacity. For example an 80C, 1300mAh LiPo can output 80*1.3 = 104 Amps.

C-rating Explained

When purchasing a VRLA (Valve Regulated Lead Acid) battery, the user will note that the battery will display an Amp-hour to a 'C-rating'. C-rating describes how much current the battery will deliver over the set time period. Being 20 hours for C20, 10 hours for C10 and 5 hours for C5.

The C rate charge or discharge time changes in relation to the rating. For example, 1C is equal to 60 minutes. Here is a simple formula to calculate time. Examples: just take mentioned example above as our example, according to “Cr=I/E”, we calculate “50amps,200ah” and get 0.25C.

The battery C Rating is the measurement of current in which a battery is charged and discharged at. 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.

The industry standard for vaguely describing how powerful a battery is for its size when it's new is the C rating, which tells you how much current it can handle for its charge capacity. It's simply maximum current divided by the charge capacity.

The C rating stands for discharge rate, and describes how fast a battery can be discharged safely. If a battery is rated at 50C and has a capacity of 5000mAh, it means that safely handle a discharge rate of 50 x 5000mAh = 250.000mAh = 250Ah.

30C high rate lithium polymer （lipo）battery is generally refers to support up to 30 current size discharge high rate battery, like this 30C high rate battery is generally lipo batteries can do, and there are a variety of model sizes, mostly custom class high rate battery.

Which is better, C10 or C20? ›

The main difference lies in their discharge rates, affecting their applications. C10 batteries are designed for higher instantaneous power demands, while C20 batteries are suitable for steadier, lower discharge rates, impacting factors such as cycle life and depth of discharge.

Chevy C10 and C20 Differences. The obvious difference between the C10 and the C20 is that one is a half-ton and the other a three-quarter-ton truck. These classifications don't refer to their respective curb weights, but rather to their payload capacity.

To calculate the C Value, subtract the initial value from the final value and then divide by the initial value. The result is a dimensionless number that represents the relative change.

The C rating stands for discharge rate, and describes how fast a battery can be discharged safely. If a battery is rated at 50C and has a capacity of 5000mAh, it means that safely handle a discharge rate of 50 x 5000mAh = 250.000mAh = 250Ah.

C - Rating

It is closely tied to capacity and has no relationship to voltage. In short the C rating signifies the maximum continuous output that the battery can maintain. Strictly speaking the C value multiplied by the capacity is the maximum continuous current output which we measure in Amps.

The formula for calculating the capacity of a lithium ion polymer battery is: capacity (AH) = constant discharge current (A) × discharge time (H). The battery on the mobile power supply usually uses a lithium polymer battery. The choice of lithium polymer battery mainly has several indicators to meet the demand.
