Storing the Battery

This section describes how to properly store the DeltaQuad Evo Li-ion baterry.

• The battery should be stored in a safe, dark location at temperatures between 5 and 30 degrees Celsius.

• If the battery is fully discharged or fully charged, perform a storage charge (approximately 50% charge or 3.7V per cell) before long-term storage. Use the Storage mode on the charger for this purpose. Storing batteries at 50% charge helps reduce stress on the cells, which can significantly extend the battery’s overall lifespan.

• During long-term storage (3+ months), it is recommended to cycle charge the batteries at least once. Fully charge the battery to 100%, then discharge it to a storage charge level of 50%.

• Keep the battery out of reach of children and animals. Avoid placing it near heat sources, such as furnaces or heaters.

• Always keep the battery dry and do not expose it to water or any other fluids.

• Remove the battery from the UAV when it is not in use.

The lifespan of Li-ion batteries is often measured by the number of charge-discharge cycles they can undergo before their capacity degrades to a certain point, usually around 80% of the original capacity. The DeltaQuad Evo Li-ion battery is rated for 600 or more cycles before noticeable degradation occurs.
