Introduction about lipo chargers and correct charging method



With the development of mobile Internet and electric vehicles, lipo chargers have higher energy density, lighter weight, longer service life and more stable performance. As a result, they have become one of the most commonly used batteries in mobile devices and electric vehicles. 


Demand for lipo chargers is growing. Polymer lithium batteries have many benefits over traditional nickel-metal hydride and lead-acid batteries. In response to this demand, the production of lipo chargers are becoming increasingly important.

1. Working principle of lipo chargers

The lithium polymer charger is higher than the DC or alternating current of the batteries, through rectification and voltage regulation to obtain a constant voltage and constant current suitable for battery charging. Connect the cathode and anode poles to the cathode and anode poles of the batteries, so that the lithium ions in the batteries are rearranged to the anode plate to complete the charging process.

2. What are lipo chargers

Lithium polymer charger is a device that can convert electrical energy into battery chemical energy, which can make polymer lithium batteries full of electric energy.

The main feature of the lipo chargers are that it can achieve fast charging in a short time and can ensure the safety and stability of charging. These characteristics make lipo chargers widely used for mobile devices such as electric vehicles, smartphones, tablets, notebooks, and video cameras. The types of lipo chargers including: 

● Categorized by function

  • Fast charger

A fast charger is a charger that can fully charge polymer lithium batteries in a short time, and usually only takes 1 to 2 hours to complete the charge.

  • Normal charger

Normal chargers take longer to complete charging, often taking hours or longer to fully charge the batteries.

  • Solar charger
  • Car charger

Among them, fast chargers and ordinary chargers are the two most common. When choosing lipo chargers, you need to consider factors such as the power, charging speed and price of the charger you need. In general, the higher the power and the faster the charging speed of the lipo chargers, the higher the price.

Therefore, you need to make trade-offs when choosing according to your needs. If you need high-speed charging or use a solar charger, you can choose a high-power fast charger or a solar charger. If you only need ordinary charging, you can choose a common charger with lower power and a more affordable price.

In short, lipo chargers have become one of the most common non-equipment items in modern life. With the popularity of mobile devices and electric vehicles, the demand for lipo chargers will also increase.

Therefore, top 10 lithium battery companies in the world also actively produce high quality, high performance of lithium polymer charger. The lipo chargers are charging device capable of charging a battery. The lipo chargers are widely used in various electronic devices.

3. Advantages of lipo chargers

Compared to traditional chargers, lipo chargers have many advantages.

● Fast charging speed

At the same time, the lithium polymer charger can also fully charge the batteries in a short time.

● High efficiency and stability

The safety of the batteries can be guaranteed.

● Intelligent features

Different lipo chargers can be intelligently adjusted according to the type and needs of charging equipment to achieve the best charging effect. For example, during the process of charging a mobile phone, the level and type of the phone batteries can be automatically detected to ensure a safe and efficient charging experience.

● Fast charging combined with slow charging

Lipo chargers also have some other characteristics. For example, lithium battery polymer chargers can perform functions such as fast charging, slow charging, and balanced charging.

The fast charging function can fully charge the batteries in a short time, and the slow charging function can gradually charge the batteries to achieve a more stable charging effect. The balanced charging function ensures that each cell of the li battery can be fully charged, thereby extending the life of the battery.

4. How to choose a portable rechargeable battery

Lithium-ion battery or lithium-polymer battery, which is the most suitable?

● Compare from manufacturing costs

Traditional lithium-ion is very different from the manufacture of lithium polymer. For lifepo4 battery, producing batteries requires a lot of expensive automation equipment and tools. Cylindrical battery configurations have become a workhorse in the industry, becoming the most commonly used configuration in a variety of applications.

As rechargeable lithium chemistry matures, this is also the most advanced technology. Lithium-polymer battery tools and equipment are less expensive to manufacture. The overall investment cost of establishing a battery assembly process is also lower.

The lithium-polymer structure allows for the manufacture of bendable batteries. The design and development of a lithium polymer battery will cover all the internal space within a given battery enclosure. This corresponds to providing the maximum achievable capacity within the battery pack.

● Compare from battery shape

Since all the internal space (cylindrical voids) inside the battery case (or plastic case) is not used, the use of cylindrical batteries may not provide the highest capacity. Professional-sized lithium-polymer batteries can be manufactured to completely fill the interior space.

From a weight perspective, traditional can batteries weigh more than lithium polymers in specific applications due to the lighter weight of aluminum foil bags. As far as environmental concerns are concerned, all lithium-ion batteries and lithium-ion batteries/batteries need to be recycled appropriately and should be disposed of in the normal waste stream. As with any battery, participation in a formal recycling program is encouraged.

5. The correct charging method of polymer lithium battery

When charging lithium polymer batteries, it is best to use the original special charger for the charger, otherwise it will affect or damage the lithium polymer battery. Polymer lithium-ion batteries are best charged slowly to prevent fast charging, and repeated charging and discharging will affect the life of polymer lithium-ion batteries.

If the phone is not used for more than 7 days, the lithium polymer battery should be fully used before use. Polymer lithium-ion batteries have battery self discharge. The longer the polymer lithium-ion battery charging time, the worse. Concerning ordinary chargers, when the polymer lithium-ion battery is full, the charging should be stopped immediately, otherwise the polymer lithium-ion battery will affect the battery performance due to overheating.

The correct charging method of polymer lithium battery


After the lithium polymer battery is charged, try to prevent it from being placed on the charger for more than 10 hours. If not in use for a long time, separate the phone from the lithium polymer battery.

6. Conclusion

In general, lipo chargers are efficient, intelligent and stable charging devices. It can meet various charging needs and has good safety performance. At the same time, the application of lithium polymer battery chargers are also expanding, and they will be used in more fields in the future.
