If the rechargeable battery is damaged or the outer casing is swollen (e.g. due to a crash causing dam
-
age to the quadrocopter), do not recharge it. This may cause a fire or explosion!
Never store a damaged rechargeable flight battery in an apartment or in a house/garage. Damaged or
swollen lithium batteries may catch fire.
• Always use a compatible charger to charge lithium batteries and ensure that the charging specifications
are correct. Do not use NiCd, NiMH or lead-acid battery chargers, as these may cause a fire or explo-
sion! Always select the correct charging specifications for your rechargeable battery.
• If you charge a rechargeable lithium battery with more than one cell, be sure to use a so-called balancer
(the rechargeable battery supplied with the quadcopter has only one cell).
• The charge rate for LiPo/Li-ion batteries must not exceed 1 C (or the value stated in the battery instruc-
tions). This means that the charging current must not exceed the battery capacity (e.g. battery capacity
= 1000 mAh, max. charging current = 1000 mA = 1 A).
•
The discharge current must not exceed the value stated on the battery.
For example, if "20C" is printed on the LiPo/Li-ion battery, the maximum discharge current is 20 times
the battery's capacity (e.g. battery capacity = 1000 mAh, max. discharge current = 20C = 20 x 1000 mA
= 20 A).
Exceeding the maximum current may cause the battery to overheat or become misshapen, which can
lead to a fire or explosion!
The printed value (e.g. 20C) indicates the maximum current that the battery can deliver for a short period.
The continuous current should not be higher than one half of the stated value.
•
Make sure that a lithium rechargeable battery does not become deeply discharged. This may destroy the
battery or cause permanent damage.
If your model does not have overdischarge protection or a low battery indicator, stop using it before the
battery becomes empty.
