Maintenance and repair of the eBee X
safety action on is recommeded to optimise flight time and safety²². Con-
sider taking the drone to its landing spot before the low endurance Warn-
ing if you judge that to be necessary.
• Minimise the number of times you allow the battery charge to drop below
10%.
• Avoid taking the battery down to 0% charge. This can greatly reduce bat-
tery lifetime and reliability.
Deep discharge
eBee X batteries’ 4 cells must remain balanced and stay above a minimum volt-
age. Following a deep discharge —one or more of the cells are pushed below
2.5 V —they become damaged, affecting the reliability of the battery. If this has
happened to a battery, it will be no longer possible to charge that battery.
Gradual discharge when not in use
Even when the battery is not in use, it will continue to gradually discharge (be-
tween 2 and 6% per month). Eventually, the battery could enter a state of deep
discharge.
To avoid this:
• After flying, do not leave the battery in a low-charge condition for a long
time. Recharge the battery as soon as possible.
• When batteries are in storage, check the battery level every 3 months and
recharge to 70% when necessary.
