STATE OF HEALTH
The state of health is determined by how much energy the battery can still store. It is an indicator of the
flight time that this battery can provide on a full charge. Old batteries with many cycles will have a lower
state of health, and provide shorter flight times when compared to brand new ones.

STORAGE MODE
Batteries are best stored at 50% charge to avoid long term chemical decay. ELIOS 3 batteries will
automatically start to discharge to this level if left unused for 5 days, but you can also trigger this process
