High Rate Discharge LiPo Batteries 40C

Accurate Size & Safe with Japan IC+Mos & Density Capacity

If you know the continuous current and the capacity of the pack you want, you can easily determine the C rate you need. If you are drawing 5A from a 1000mAh pack, simply take the current and divide by the capacity: 5A = 5000mA, 5000mA / 1000mAh = 5C.
High Rate LiPo batteries 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 batteries, the burst rate is 10C, which means the battery can provide 10 x 1000mA=10000mA current for several seconds.

High Discharge current C rating describes how quickly a battery can be discharged.
Due to the high rate discharge LiPo battery use the electrode material which is favorable for high rate discharge, the internal resistance design of the electrode is smaller than that of the standard battery, so the rate battery has high discharge platform, high discharge efficiency, and high output power and energy.

Batteries with high power provide rapid discharge capability at high drain rates such as in power tools or automobile starter battery applications. Typically, high power batteries have low energy densities.

High rate discharge LiPo batteries can be rapidly discharged in a short period. If you select the inequality High rate discharge LiPo batteries, it may lead to short-circuiting of  LiPo Batteries and even have destroyed to your devices. So it is important to select an unbeatable one to work for you. Our High rate discharge LiPo battery engineers put into more design more effort and high technology to design, manufacture High rate discharge LiPo batteries, and custom special PCM that for some personal need. The special PCM can ensure High rate discharge LiPo batteries to be more stable, safe and durable when high discharging.

Battery manufacturers often specify capacity at a given discharge rate, temperature, and cut-off voltage. The specified capacity will depend on all three factors. A battery that appears to have a high capacity on a spec sheet may actually perform poorly if the current drain for the application is higher. For instance, a battery rated at 2 Ah for a 20-hour discharge cannot deliver 2 A for 1 hour, but will only provide a fraction of the capacity.

What are Capacity And Discharge?

A LiPo battery's capacity is the amount of electric charge it can deliver at the rated voltage. The more electrode material contained in the cell the greater it is capacity. A small cell has less capacity than a larger cell with the same chemistry, although they develop the same open-circuit voltage. Capacity is measured in units such as amp-hour (A·h). The rated capacity of a LiPo battery is usually expressed as the product of 20 hours multiplied by the current that a new LiPo battery can consistently supply for 20 hours at 68 °F (20 °C) while remaining above a specified terminal voltage per cell. For example, a LiPo battery rated at 100 A·h can deliver 5 A over a 20-hour period at room temperature. The fraction of the stored charge that a LiPo battery can deliver depends on multiple factors, including battery chemistry, the rate at which the charge is delivered (current), the required terminal voltage, the storage period, ambient temperature and other factors.

What is mAh?

The A is capitalized because, under the International System of Units, “ampere” is always represented with a capital A. The term mAh is an abbreviation for “milliampere-hour,” and it’s a way to express the electrical capacity of smaller LiPo Batteries. With larger batteries, like car LiPo Batteries, we usually use ampere-hours, or Ah. There is 1000 mAh in a single Ah. mAh is calculated by multiplying the amount of time the LiPo batteries last by the amperes of the discharge current.

Simple Guidelines for Discharging LiPo Batteries :

Heat increases LiPo batteries performance but shortens life by a factor of two for every 10°C increase above 25–30°C (18°F above 77–86°F). Always keep the LiPo Batteries cool.
Prevent over-discharging. Cell reversal can cause an electrical short.
On high load and repetitive full discharges, reduce stress by using larger LiPo Batteries.
A moderate DC discharge is better for a LiPo battery than a pulse and heavy momentary loads.
A LiPo battery exhibits capacitor-like characteristics when discharging at high frequency. This allows higher peak currents than is possible with a DC load.
Nickel- and lithium-based LiPo Batteries have a fast chemical reaction; lead-acid is sluggish and requires a few seconds to recover between heavy loads.
All LiPo Batteries suffer stress when stretched to maximum permissible tolerances.

Rigorous Testing and Fast Delivery

All High Rate LiPo Batteries will be rigorously tested before shipping. It is significant to ensure a higher quality of  LiPo Batteries. What’s more, we stock additional High Discharge C rating LiPo Batteries for samples and small order, you can get it faster than making a new sample.

To select the Best LiPo Batteries for your RC helicopter

To select a LiPo Battery for your RC helicopter, you first need to know what voltage you require and how much current you will be drawing continuously. If the motor in your RC helicopter is rated to work with 14.8V, you would need a 4 cell LiPo battery. If you need to draw 10A, and you would like your RC helicopter to have a 10 minute (1/6th of an hour = 6C) flight, you would need a LiPo battery with 10A / 6 = 1.7A = 1700mAh. This means you would need to put a 3s 1700mAh LiPo battery with a C rating of 6 or higher in your RC helicopter.

Basics about Discharging

The purpose of a LiPo battery is to store energy and release it at a desired time. This section examines discharging under different C-rates and evaluates the depth of discharge to which a LiPo Battery can safely go. The document also observes different discharge signatures and explores battery life under diverse loading patterns.

The electrochemical LiPo Batteries has the advantage over other energy storage devices in that the energy stays high during most of the charge and then drops rapidly as the charge depletes. The super capacitor has a linear discharge, and compressed air and a flywheel storage device is the inverse of the LiPo Batteries by delivering the highest power at the beginning. Figures 1, 2 and 3 illustrate the simulated discharge characteristics of stored energy.

Most rechargeable LiPo batteries can be overloaded briefly, but this must be kept short. LiPo Battery longevity is directly related to the level and duration of the stress inflicted, which includes charge, discharge and temperature.
Remote control (RC) hobbyists are a special breed of LiPo batteries users who stretch tolerance of “frail” high-performance LiPo batteries to the maximum by discharging them at a C-rate of 30C, 30 times the rated capacity. As thrilling as an RC helicopter, race car and fast boat can be; the life expectancy of the packs will be short. RC buffs are well aware of the compromise and are willing to both pay the price and to encounter added safety risks.

To get maximum energy per weight, drone manufacturers gravitate to cells with a high capacity and choose the Energy Cell. This is in contrast to industries requiring heavy loads and long service life. These applications go for the more robust Power Cell at a reduced capacity.


Simple Guidelines for Discharging LiPo Batteries
  • Heat increases LiPo battery performance but shortens life by a factor of two for every 10°C increase above 25–30°C (18°F above 77–86°F). Always keep the LiPo battery cool.
  • Prevent over-discharging. Cell reversal can cause an electrical short.
  • On high load and repetitive full discharges, reduce stress by using a larger LiPo battery.
  • A moderate DC discharge is better for a LiPo battery than pulse and heavy momentary loads.
  • A LiPo battery exhibits capacitor-like characteristics when discharging at high frequency. This allows higher peak currents than is possible with a DC load.
  • Nickel- and lithium-based LiPo batteries have a fast chemical reaction; lead acid is sluggish and requires a few seconds to recover between heavy loads.
  • All LiPo batteries suffer stress when stretched to maximum permissible tolerances.
Units of Battery Capacity: Ampere Hours

The energy stored in a battery, called the battery capacity, is measured in either watt-hours (Wh), kilowatt-hours (kWh), or ampere-hours (Ahr). The most common measure of battery capacity is Ah, defined as the number of hours for which a battery can provide a current equal to the discharge rate at the nominal voltage of the battery. The unit of Ah is commonly used when working with battery systems as the battery voltage will vary throughout the charging or discharging cycle. The Wh capacity can be approximated from the Ahr capacity by multiplying the AH capacity by the nominal (or, if known, time average) battery voltage. A more accurate approach takes into account the variation of voltage by integrating the AH capacity x V(t) over the the time of the charging cycle. For example, a 12 volt battery with a capacity of 500 Ah battery allows energy storage of approximately 100 Ah x 12 V = 1,200 Wh or 1.2 KWh. However, because of the large impact from charging rates or temperatures, for partial or accurate analysis, additional information about the variation of battery capacity are also provided by lipo batteries manufacturers.

Operating Voltage Range

Max Operating Voltage Range: 2.75V to 4.2V
Max Charge Voltage: 4.2V±50mV
Discharge Cut-off: 2.75V
Internal Impedance: <200mΩ
Expected Cycle Life: 500 cycles ≥ 80%

The voltage for long-time storage of Lithium polymer batteries used in the R/C model should be 3.6~3.9V range per cell, otherwise, otherwise it may cause damage to the battery.

Lithium polymer batteries packs also see widespread use in airsoft, where their higher discharge currents and better energy density compared to more traditional NiMH batteries have very noticeable performance gain (higher rate of fire). The high discharge currents do damage the switch contacts due to arcing (causing the contacts to oxidize and often deposit carbon), so it is advised to either use a solid-state MOSFET switch or clean the trigger contacts regularly.

Charge & Discharge current of the LiPo Batteries?

The Standard LiPo Battery(Capacity below 3000mAh) ‘s max discharge current is 1C, and the max charge current is 0.5C, The standard charge current is 0.2C.
The standard discharge current is 0.5C

Standard LiPo Batteries Max discharge is 3A.
Max charge current is 2A.
High Rate LiPo Batteries depend on the C rate and PCM.

Lithium polymer batteries have a flexible, foil-type (polymer laminate) case, so they are relatively unconstrained.
Charge/discharge at 0.5C/0.5C, 80% residual capacity after 500 cycles.

Lithium polymer batteries provide manufacturers with compelling advantages. They can easily produce Lithium polymer batteries of almost any desired shape. For example, the space and weight requirements of mobile devices and notebook computers can be met. They also have a low self-discharge rate, which is about 5% per month.
