Lithium batteries can be roughly divided into two categories: lithium metal batteries and lithium ion batteries. Lithium-ion batteries do not contain metallic lithium and are rechargeable. The fifth generation of rechargeable batteries, lithium metal batteries, was born in 1996, and its safety, specific capacity, self-discharge rate, and performance-price ratio are superior to those of lithium-ion batteries. Due to its own high-tech requirements, companies in only a few countries are producing such lithium metal batteries.
The UAV battery uses a lithium-ion battery, which is characterized by fast charging speed, long battery life, and relatively stable performance.
