What are Capacity and Discharge?

A 3.7V Rechargeable 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 its capacity. Although they develop the same open-circuit voltage, a small 3.7V Rechargeable LiPo Battery has less capacity than a larger cell with the same chemistry. Capacity is measured in units such as amp-hour (A·h). The rated capacity of a 3.7V Rechargeable LiPo Battery is usually expressed as the product of 20 hours multiplied by the current that a new 3.7V Rechargeable 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 3.7V Rechargeable LiPo Battery rated at 100 Ah can deliver 5 A over a 20-hour period at room temperature. The fraction of the stored charge that a 3.7V Rechargeable LiPo Battery can deliver depends on multiple factors, including 3.7V Rechargeable LiPo Batteries 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 3.7V Rechargeable LiPo 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 3.7V Rechargeable LiPo Batteries last by the amperes of the discharge current.

Simple Guidelines for Discharging 3.7V Rechargeable LiPo Batteries:

Heat increases 3.7V Rechargeable 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 3.7V Rechargeable LiPo Battery cool.
Prevent over-discharging. Cell reversal can cause an electrical short.
On high load and repetitive full 3.7V Rechargeable LiPo Batteries discharges, reduce stress by using a larger 3.7V Rechargeable LiPo Battery.
A moderate DC 3.7V Rechargeable LiPo Batteries discharge is better for a 3.7V Rechargeable LiPo Battery than pulse and heavy momentary loads.
A 3.7V Rechargeable LiPo Battery exhibits capacitor-like characteristics when discharging at high frequency, 3.7V Rechargeable LiPo Batteries allow 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 3.7V Rechargeable LiPo Batteries suffer stress when stretched to maximum permissible tolerances.

Are 3.7V Rechargeable LiPo Batteries assembled with PCM / NTC / Connectors?

We stock all 3.7V Rechargeable LiPo Batteries are cells not finished LiPo batteries.

The Cell can add PCM and connector as your request, LiPol will assemble NTC/PCM/Connectors or series/parallel batteries according to your requirements. What’s more, the lead time is just 3-5days.

What is the life of 3.7V Rechargeable LiPo Batteries (Self-discharge)?

Standard: After 500 cycles, the capacity will be <80%. It will be affected by the situation of discharge/recharge, and 3.7V Rechargeable LiPo Batteries environment like temperature, humidity.
Temperature range:
Charge: 10 to + 45 ° C
Discharge: -20 to + 60 ° C
Charge retention / Storage:
1 year at -20 to 20 ° C> 70%
3 month at -20 to 45 ° C> 70%
1 month at -20 to 60 ° C> 70%

If the temperature is too low, the 3.7V Rechargeable LiPo Battery capacity will be significantly reduced;
If the temperature is too high, the 3.7V Rechargeable LiPo Battery is prone to internal short circuits;

In addition, we can make encryption that is suitable for low temperature or high temperature but need to re-create and use a special electrolyte.

3.7V Rechargeable LiPo Batteries that lose 20% of their capacity must be removed from service and disposed of properly. Discharge the 3.7V Rechargeable LiPo Battery to 3V/Cell, making sure output wires are insulated, then wrap 3.7V Rechargeable LiPo Battery in a bag for disposal
Product Warranty: Product warranty is limited to original defects in material and workmanship for 90 days from the day of purchase. Warranty does not cover collateral damage, misuse, abuse, incorrect charging, and other inappropriate use of this product.

Why doesn’t the LiPo Battery Pack Be Recharged?

When the LiPo batteries pack is charged, it can be divided into the following reasons: the charger is reversed, or the charger is faulty; the protection board protection is not restored, or the protection board is defective; the LiPo Batteries pack is disconnected from the external use of the appliance.

For the above-mentioned unfavorable phenomena, look for the reasons in turn. Whether the charger is connected reversely, whether the positive and negative poles of the LiPo Batteries pack are connected reversely; re-enable the appliance to release the protection board protection, measure whether the protection board MOS tube has driving voltage; find out whether the wiring connection is loose or disconnect.

Why LiPo Battery shows 0V?

What’s the burst current?

The motor demand a highly current discharge requirement, which needs a high rate of discharge battery.

It shut down due to over-discharge protection.

We assume that the voltage down to 0V due to the protection circuits works:

It shuts down to 0V, whether that’s high temperature, excessive current, or a short circuit in a conductor, thus protecting the electrical circuit it’s part of from damage.

About LiPo Battery Specification?

Pls clarify the detail before you place the order, 

We can adjust according to your requirements. 

The thickness of the cable is determined by capacity, there is some estimation when we revise the specification, 

In general, the specification datasheet of the battery and actual production have some differences normally.

LiPo Batteries Application:

 

The Agricultural Application of LiPo Batteries Although lithium batteries in agriculture are a relatively new phenomenon; Those LiPo Batteries are quickly becoming the popular choice for those looking for a more efficient and environmentally-friendly way to power their farm equipment.

LiPo Batteries are used in automotive equipment: electric vehicles and hybrid vehicles.

Those LiPo Batteries are getting more popular due to their high energy density and low weight. LiPo Batteries have several advantages over traditional lead-acid batteries. They are much lighter, so they save weight and space.

They also have a higher energy density to store more energy in a given space. Another advantage of lithium batteries is that they can quickly recharge. It is essential for electric vehicles, which need to be able to recharge rapidly to keep up with the demands of stop-and-go traffic.

People’s demand for communications equipment also increases with the rapid development. To meet the needs of people’s lives, communication equipment manufacturers are also constantly improving their products.

For example, in terms of battery life, communication equipment is usually equipped with a LiPo battery, which has the advantages of long life, small volume, and lightweight. The application of LiPo Batteries in communication equipment can divide into two aspects: the power supply of communication equipment and the other is the power supply of mobile phones.

LiPo Batteries: Basics about Discharging

The purpose of a LiPo battery is to store energy and release it at the 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 have 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 supercapacitor 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 Batteries 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 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 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 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.

The energy stored in a LiPo Battery called the LiPo Battery capacity is measured in either watt-hours (Wh), kilowatt-hours (kWh), or ampere-hours (Ahr). The most common measure of LiPo battery capacity is Ah, defined as the number of hours for which a LiPo Battery can provide a current equal to the discharge rate at the nominal voltage of the LiPo battery. The unit of Ah is commonly used when working with LiPo battery systems as the LiPo 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) LiPo battery voltage. A more accurate approach takes into account the variation of voltage by integrating the AH capacity x V(t) over the time of the charging cycle. For example, a 12 volt LiPo battery with a capacity of 500 Ah LiPo 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 LiPo battery capacity are also provided by lipo batteries manufacturers.

LiPo Batteries: 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 LiPo Batteries used in the R/C model should be 3.6~3.9V range per cell, otherwise, otherwise it may cause damage to the LiPo Battery.

LiPo 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.

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

LiPo Batteries provide manufacturers with compelling advantages. They can easily produce LiPo 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.

How should lipo batteries be stored?

Always store your LiPo batteries at room temperature, and charge them per 6-8 months.
