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.
