Understanding the 802540 Battery
The 802540 battery refers to a lithium polymer (LiPo) battery that measures approximately 8mm thick, 25mm wide, and 40mm long. These compact dimensions make it ideal for smaller drones or specific models that require a lightweight power source. Knowing this helped me narrow down compatible drones before buying.
