Battery Management

Storage​

To ensure the longevity and safety of your Lithium-Polymer battery packs, follow these important guidelines:

  • Storage Voltage:

    • If the battery will not be used for more than 7 days, make sure it is left at the storage voltage of 3.85V per cell.
    • If the battery is fully charged but not used, or if it is discharged after a flight, use the charger to bring it down to the storage voltage.

  • Storage Conditions:

    • Store the battery in a cool, dark environment.
    • Most importantly, ensure the storage location is fireproof to reduce the risk of accidents.

Proper storage significantly extends the life of your battery and ensures safe operation.

Replacement​

The replacement cycles of a battery pack are measured in charge/discharge cycles rather than flight hours. For the batteries used in heavy-lifter drones like the Hercules X8, the average battery lifespan is approximately 300 cycles.

Signs It's Time for a Replacement:​

  • Battery performance drop: When the battery is unable to charge beyond 80% of its full capacity, it indicates the battery has reached the end of its service life.

To ensure optimal performance, replace the battery once it reaches this threshold.

Disposal​

The main rule to guarantee a safe disposal of a Lipo battery is to completely discharge the battery down to 0 Volts. You can do this in two ways:

  1. Connect the battery to a light bulb for 2-3 days until the light turns off.
  2. Submerge the battery in a bucket with water and mix in 35g of salt per liter of water for 2-3 weeks.

If the battery cannot be fully discharged, please contact a professional battery disposal/recycling agent for further assistance.

Strictly follow your local regulations regarding the disposal and recycling of batteries.
