Always use a compatible charger to charge lithium batteries and ensure that the charging specications
are correct. Do not use NiCd, NiMH or lead-acid battery chargers, as these may cause a re or explo-
sion! Always select the correct charging specications for your rechargeable battery.
Always use a balancer when charging a lithium battery with more than one cell (the built-in quadcopter
battery only has one cell).
The charge rate for LiPo/Li-ion batteries must not exceed 1C (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 deformed, which can
lead to a re 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.
Do not allow the lithium battery to overdischarge. 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.
