Lithium ion Battery LP21700A 3.7V 4800mAh

A rechargeable lithium ion battery is a type of rechargeable battery commonly used in electronic devices such as smartphones, laptops, and electric vehicles. lithium-ion batteries are known for their high energy density, long cycle life, and low self-discharge rates.

lithium ion batteries work by storing and releasing energy through the movement of lithium ions between two electrodes, which are typically made of lithium cobalt oxide (positive electrode) and graphite (negative electrode). When the battery is charged, lithium-ions move from the positive electrode to the negative electrode, where they are stored. When the battery is discharged, the ions move back to the positive electrode, releasing energy in the process.

One advantage of lithium ion batteries is that they do not suffer from the “memory effect” that plagued older rechargeable batteries. This means that they can be recharged at any time without having to fully discharge them first. However, lithium-ion batteries can be sensitive to high temperatures and can degrade over time, which can reduce their overall lifespan.

Overall, lithium ion batteries have become increasingly popular due to their high performance, low self-discharge rates, and relatively long lifespan.

Are you looking for the right lithium battery for your project? Look no further! We have pre-made 3.7v 21700 hard shell lithium-ion batteries in stock, as well as high-capacity rechargeable Li-ion batteries. As a reliable China lithium battery manufacturer and supplier, we offer both 21700, 26650 and 18650 options.

To choose the perfect battery for your project, there are a few things to consider. First, determine how much space you have available for the battery. Then, you’ll need to know the battery’s capacity, voltage, max working current, and continuous working current. You may also need additional components like a protection circuit module, wires, thermistor, or connectors. Keep in mind that the battery’s weight will increase with its capacity. For example, a 2000mAh lithium polymer battery weighs approximately 20g.

If you require a higher working voltage, we can create a 2s or 3s battery pack using single batteries, such as a 7.4v lithium-ion battery pack or an 11.1v lithium polymer battery. For more information, please don’t hesitate to contact us.
