Store Batteries in a Cool, Dry Place:
Storing batteries in a cool, dry place prevents degradation and maintains performance. High temperatures can accelerate chemical reactions within the battery, leading to quicker loss of capacity. Ideal storage temperatures range between 20°C to 25°C (68°F to 77°F). Long-term storage should also include a state of charge between 40% to 60%. -
Use a Dedicated Battery Charger:
Using a dedicated battery charger ensures proper voltage management during charging. It is designed to suit the specific chemistry and voltage of LiPo batteries, preventing overcharging. Excessive voltage can lead to thermal runaway—a dangerous situation where the battery overheats and potentially explodes. -
Avoid Deep Discharges:
Avoiding deep discharges extends battery lifespan significantly. LiPo batteries should not be discharged below 3 volts per cell. A voltage below this threshold can result in irreversible damage. Setting a voltage cut-off in the flight controller can help enforce this practice. -
Monitor for Physical Damage:
Monitoring for physical damage, such as swelling or punctures, is crucial for safety. Damaged batteries can become hazardous and should be disposed of properly according to local regulations. Regular visual inspections can help identify potential issues before they lead to malfunction. -
Clean Battery Terminals:
Cleaning battery terminals helps ensure good electrical contacts. Corrosion or dirt can increase resistance and reduce performance.
