LiPo batteries, or lithium polymer batteries, are a type of rechargeable battery commonly used in various electronic devices, including drones, smartphones, and remote-controlled vehicles. They are known for their lightweight design and ability to provide high energy density, which means they can store a lot of energy in a small space. These batteries consist of a polymer electrolyte instead of a liquid one, making them more flexible and safer in certain applications. However, they require careful handling and charging to prevent issues like swelling or fire, emphasizing the importance of using a compatible LiPo charger and following safety guidelines.
