Discharging a drone battery to a safe level is vital for its longevity and performance. Lithium Polymer (LiPo) batteries, commonly used in DJI drones, require specific care during discharge to prevent irreversible damage. These batteries function by storing energy in a polymer electrolyte, which can degrade if the battery is left in a discharged state for too long or if it is over-discharged. Maintaining a safe discharge level helps preserve the battery’s chemical composition and prevents issues such as swelling, reduced capacity, or complete failure.

LiPo batteries typically have a nominal voltage of 3.7 volts per cell; however, they should not be discharged below 3.0 volts per cell. Continuous over-discharging can lead to a condition known as “cell damage,” where the internal components become compromised, resulting in decreased battery performance and potential hazards such as fires or explosions.
