Get Lithium Polymer Battery Pack

Lithium polymer batteries are generally provided in packages with more than two separate battery cells. For example, an electric RC helicopter uses a 3-cell package. Each of these battery cells has a nominal voltage of 3.7 V; This means that each cell can work if its load is kept between 3.0 and 4.2V.

Exceeding or falling below this range can damage the cell and render it unusable or worse, become extremely unstable and explode. You can also buy high-tech lithium polymer battery packs via


When the battery is in use, the power supply of each cell is not the same. As a result, the battery cells remain unbalanced at the end of each flight. An unbalanced charger will stop charging the battery as soon as the entire pack has been charged and ignore the cells. As a result, the battery becomes more unbalanced with each charge, and battery performance decreases.

A balanced charger eliminates the symptom of battery cell imbalance by charging each cell individually. Make sure the cell voltage remains balanced at the end of each charge. In essence, the charger prolongs the life of the battery, improves its performance, and keeps the case stable and reliable.

The lithium battery is disposable. They have lithium metal or lithium compounds. This battery differs from other batteries by its high charge density and its high unit price. Depending on the design and chemicals used, lithium cells can produce a voltage of 1.5 V to approximately 3.7 V. Lithium batteries are widely used in products such as portable consumer electronics.

The lithium-polymer battery is a secondary rechargeable battery. This type of battery generally consists of several identical secondary cells to increase discharge current capacity and is often available in series packs to increase the total available voltage.
